Problem with string (string contains brace characters and a plus sign)

I have a problem with regex. The variable media.Value may contain the characters "() +" which causes an error in the regex and prevents it from working.
My code
Match renderMatch = Regex.Match(mediaMatch.Groups[0].Value, "(?<=\"name\":\"" + media.Value + "\",\"render\":).*?(?=,)");
Match mutedMatch = Regex.Match(mediaMatch.Groups[0].Value, "(?<=\"muted\":).*?(?=,\"name\":\"" + media.Value + "\")");
json I work with
[{"alignment":5,"cx":844.0,"cy":264.0,"id":4,"locked":false,"muted":false,"name":"Text (GDI +)","render":true,"source_cx":844,"source_cy":264,"type":"text_gdiplus_v2","volume":1.0,"x":549.0,"y":383.0},{"alignment":5,"cx":1920.0,"cy":1080.0,"id":3,"locked":false,"muted":false,"name":"Color","render":true,"source_cx":1920,"source_cy":1080,"type":"color_source_v3","volume":1.0,"x":0.0,"y":0.0}]
As long as there are no "()" in the name field everything works. For example:
Working
"muted":false,"name":"Color","render":true
Not working
"muted":false,"name":"Text (GDI +)","render":true
The question is.
Is there any regex option that would ignore the () in string, or how else could I get an output like this:
"Text \(GDI \+\)"

You can deserialize your JSON string to strongly typed models and then gather your required fields
An example with your JSON string is: https://dotnetfiddle.net/cqkOdu
using System;
using System.Collections.Generic;
using Newtonsoft.Json;
public class Program
{
public static void Main()
{
var myJsonResponse= #"[{'alignment':5,'cx':844.0,'cy':264.0,'id':4,'locked':false,'muted':false,'name':'Text (GDI +)','render':true,'source_cx':844,'source_cy':264,'type':'text_gdiplus_v2','volume':1.0,'x':549.0,'y':383.0},{'alignment':5,'cx':1920.0,'cy':1080.0,'id':3,'locked':false,'muted':false,'name':'Color','render':true,'source_cx':1920,'source_cy':1080,'type':'color_source_v3','volume':1.0,'x':0.0,'y':0.0}]";
List<Root> myDeserializedClass = JsonConvert.DeserializeObject<List<Root>>(myJsonResponse);
foreach(var item in myDeserializedClass)
{
Console.WriteLine(item.name);
}
}
}
public class Root
{
public int alignment { get; set; }
public double cx { get; set; }
public double cy { get; set; }
public int id { get; set; }
public bool locked { get; set; }
public bool muted { get; set; }
public string name { get; set; }
public bool render { get; set; }
public int source_cx { get; set; }
public int source_cy { get; set; }
public string type { get; set; }
public double volume { get; set; }
public double x { get; set; }
public double y { get; set; }
}

How to fix Error while converting Json string to Object C#?

Im using C# to get a file from my local pc data folder.
This is the code to do that:
var _rootpath = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData) + directory;
var ENC = new Encryption();
var s = File.ReadAllText(_rootpath + "json");
var x = ENC.RijndaelDecrypt(s, App.EncryptionPassword);
This works fine so far.
x got now this value (so this is the string I want to convert to an object) :
{
"items":[
{
"id":194,
"guid":"594394",
"name":"Test",
"connectorId":248,
"customerId":1,
"customerName":"company",
"connectorTypeId":10,
"connectorTypeIcon":null,
"connectorCategoryId":1,
"vendor":"FasterForward",
"isActive":true,
"shopId":null,
"sku":null,
"workerBearerToken":"",
"workerUri":"http://localhost:9000"
}
],
"responseStatus":null
}
After this I want to convert this to an object
var _response = JsonConvert.DeserializeObject<CrmJobListResponse>(x);
This line gives an error:
{"Error converting value x to type 'ServiceModel.CrmJobListResponse'. Path '', line 1, position 991."}
ServiceModel.CrmJobListResponse:
namespace ServiceModel
{
public class CrmJobListResponse : ResponseBase
{
public CrmJobListResponse();
public List<CrmJob> Items { get; set; }
}
}
CrmJob class:
namespace ServiceModel.DTO
{
public class CrmJob : IHasId<int>
{
public CrmJob();
[Ignore]
public string WorkerBearerToken { get; set; }
[PropertyValue("sku")]
public string SKU { get; set; }
[PropertyValue("shop_id")]
public string ShopId { get; set; }
public bool IsActive { get; set; }
public string Vendor { get; set; }
public int ConnectorCategoryId { get; set; }
[Ignore]
public string WorkerRefreshToken { get; set; }
public string ConnectorTypeIcon { get; set; }
public string CustomerName { get; set; }
public int CustomerId { get; set; }
public int ConnectorId { get; set; }
[PropertyValue("jobname")]
public string Name { get; set; }
public string Guid { get; set; }
public int Id { get; set; }
public int ConnectorTypeId { get; set; }
[Ignore]
public string WorkerUri { get; set; }
}
}
Does anyone know why it can't convert my Json string to an object?
I didn't made the code myself, but I don't see why It should go wrong...

If you have a hard time creating DTOs you have some tools that may assist you https://app.quicktype.io/
You can also use paste special in VS to paste a Json directy to a C# class.
This also shows you if you malformed a Json.

Combining data from 2 databases in MVC

I am fairly new to asp.net mvc and I currently have an application that shows a number of errors. I have 2 pages that contain Application Errors and Log Errors. The data comes from 2 different databases but I am wanting to display the data from both databases on one page.
The tables have headings with different names that mean the same thing e.g. ApplicationName in the Application Database is the same thing as LogName in the Log Database.
Below is a small example of what I currently have and an example of what I am wanting.
Current
Application Errors
ID ApplicationName ApplicationMessage ApplicationDate
1 Something Hello World 01/01/2015
2 Something Else Another Message 03/01/2015
Log Errors
ID LogName LogMessage LogDate
1 Some Log A log message 02/01/2015
2 Another Log Another Log Message 04/01/2015
What I Want
Internal Errors
ID Name Message Date
1 Something Hello World 01/01/2015
2 Some Log A log message 02/01/2015
3 Something Else Another Message 03/01/2015
4 Another Log Another Log Message 04/01/2015
At the minute, I have 2 separate models for each database but I think I need to merge both models into one model that combines them both but I am unsure on how to do this. How would I be able to merge both data sources together to display the data within the same page?
Current Models
Application
[Table("ELMAH_Error")]
public class ElmahError
{
[Key]
public System.Guid ErrorId { get; set; }
public System.String Application { get; set; }
public System.String Host { get; set; }
public System.String Type { get; set; }
public System.String Source { get; set; }
public System.String Message { get; set; }
public System.String User { get; set; }
public System.Int32 StatusCode { get; set; }
public System.DateTime TimeUtc { get; set; }
public System.Int32 Sequence { get; set; }
public System.String AllXml { get; set; }
}
Log
[Table("LogEntry")]
public class LogEntry
{
[Key]
public Int64 ID { get; set; }
public DateTime LogDate { get; set; }
public Int16 Priority { get; set; }
public string SourceClass { get; set; }
public string Category { get; set; }
public string Message { get; set; }
public string UserID { get; set; }
public string ProcessID { get; set; }
}
From the models, there are a number of fields that I would like to merge as well as fields that are not similar that I would also like to include. The model below shows exactly what I want but I just don't know how to implement it.
Internal Errors
public class InternalErrors
{
public string Id { get; set; } //L:ID && E:ErrorId
public int Priority { get; set; } //L:Priority
public string Application { get; set; } //L:SourceClass && E:Application
public string Message { get; set; } //L:Message && E:Message
public string Type { get; set; } //L:Category && E:Type
public string User { get; set; } //L:UserID && E:User
public string ProcessID { get; set; } //L:ProcessID
public DateTime Date { get; set; } //L:LogDate && E:TimeUtc
public int StatusCode { get; set; } //E:StatusCode
public string AllXml { get; set; } //E:AllXml
public int Sequence { get; set; } //E:Sequence
public int ErrorCount { get; set; } //E:ErrorCount
}
I hope this is enough information for you to provide an answer, if you need anything else, let me know.
Thanks in advance

if what you want is this
Internal Errors
ID Name Message Date
1 Something Hello World 01/01/2015
2 Some Log A log message 02/01/2015
3 Something Else Another Message 03/01/2015
4 Another Log Another Log Message 04/01/2015
then create a class with name InternalErrors as follows.
public class InternalErrors
{
public int ID;
public string Name;
public string Message;
public DateTime Date;
}
Now you can write a Linq Query as follows to get data from Application Errors and Log Errors and Perform union on it.
var AppErrors=from AE in _db.ApplicationErrors select AE;
var LogErrors=from LE in _dc.LogErrors select LE;
var internerrors=AppErrors.Union(LogErrors);
var InternalErrors=(from ie in internerrors select new InternalErrors()
{
ID=ie.ID,
Message=ie.ApplicationMessage,
Name=ie.ApplicationName,
Date=ie.ApplicationDate
}).ToList();

The viewmodel approach from MRebati is the best solution.
I often find it usefull to have a base class and different implementations:
public abstract class ErrorViewModel
{
public abstract int Id { get; }
public abstract string Name { get; }
}
public class ElmahErrorViewModel
{
public ElmahErrorViewModel(ElmahError instance)
{
this.Instance = instance;
}
public ElmahError Instance { get; private set; }
public int Id { get { return Instance.ErrorId; } }
public string Name { get { return instance.Appication; } }
}
that way you can create a List<ErrorViewModel> and add entries with
var items = from e in context.ElmahErrors
select new ElmahErrorViewModel(e);
list.AddRange(items);
var items2 = from l in context.LogEntrys
select new LogEntryViewModel(l);
list.AddRange(items2);
This is very usefull since you hide the details but you still can seprate the list and access the underlying object with
var elmahErrors = items.OfType<ElmahErrorViewModel>().Select(x => x.Instance);

There are many ways to provide data from the models to the View.
One is the ViewModel. It must contain the data you want to send to view. Look at this:
using System;
public class ErrorViewModel
{
public int Id { get; set; }
public string Name { get; set; }
public string Message { get; set; }
public DateTime Date { get; set; }
}
And in the Controller you need to Create a list of this ViewModel and populate it with your data.

you can use linq
using System;
using System.Linq;
using System.Collections.Generic;
public class Program
{
public static void Main()
{
var elmahErrorList = new List<ElmahError>{
new ElmahError{ ErrorId = Guid.NewGuid(), Application = "Something",Message = "Hello World" , TimeUtc = DateTime.Now },
new ElmahError{ ErrorId = Guid.NewGuid(), Application = "Something Else",Message = "Another Message" , TimeUtc = DateTime.Now }
};
var logEntryList = new List<LogEntry>{
new LogEntry{ ID = 1, SourceClass = "Something",Message = "Hello World" , LogDate = DateTime.Now },
new LogEntry{ ID = 1, SourceClass = "Something Else",Message = "Another Message" , LogDate = DateTime.Now }
};
var internalErrorsList = new List<InternalErrors>();
var elmahErrorListinternalErrorses = elmahErrorList.Select(e => new InternalErrors
{
Id = e.ErrorId.ToString(),
Application = e.Application,
Message = e.Message,
Type = e.Type,
User = e.User,
Date = e.TimeUtc,
StatusCode = e.StatusCode,
AllXml = e.AllXml,
Sequence = e.Sequence
});
internalErrorsList.AddRange(elmahErrorListinternalErrorses);
var elmahErrorListlogEntryLists = logEntryList.Select(l => new InternalErrors
{
Id = l.ID.ToString(),
Priority = l.Priority,
Application = l.SourceClass,
Message = l.Message,
Type = l.Category,
User = l.UserID,
Date = l.LogDate
});
internalErrorsList.AddRange(elmahErrorListlogEntryLists);
internalErrorsList.ForEach(f =>
{
Console.Write(f.Id); Console.Write("\t");
Console.Write(f.Application);Console.Write("\t");
Console.Write(f.Message);Console.Write("\t");
Console.Write(f.Date);Console.Write("\t");
Console.WriteLine();
});
}
public class InternalErrors
{
public string Id { get; set; } //L:ID && E:ErrorId
public int Priority { get; set; } //L:Priority
public string Application { get; set; } //L:SourceClass && E:Application
public string Message { get; set; } //L:Message && E:Message
public string Type { get; set; } //L:Category && E:Type
public string User { get; set; } //L:UserID && E:User
public string ProcessID { get; set; } //L:ProcessID
public DateTime Date { get; set; } //L:LogDate && E:TimeUtc
public int StatusCode { get; set; } //E:StatusCode
public string AllXml { get; set; } //E:AllXml
public int Sequence { get; set; } //E:Sequence
public int ErrorCount { get; set; } //E:ErrorCount
}
public class ElmahError
{
public System.Guid ErrorId { get; set; }

Json.NET - Custom Converter - String To Int

I've got a problem regarding Json.NET and the omdbapi. I'm trying to retrieve information from the omdbapi and some properties are giving me headaches, particularly the "imdbVotes" one since it's written, in example, as "321,364" so I can't get an integer from it.
I'm betting that I need a custom converter, but I'm afraid that, at the moment, I don't really understand how to create one for my particular problem.
All other properties work well (I'm not using all of them at the moment).
This is the response for, lets say Snatch : http://www.omdbapi.com/?i=&t=snatch
This is my class :
public class MovieJSON
{
[JsonProperty(PropertyName = "Title")]
public String Title { get; set; }
[JsonProperty(PropertyName = "Year")]
public int Year { get; set; }
[JsonProperty(PropertyName = "Genre")]
public String Genre { get; set; }
[JsonProperty(PropertyName = "Director")]
public String Director { get; set; }
[JsonProperty(PropertyName = "Actors")]
public String Actors { get; set; }
[JsonProperty(PropertyName = "Plot")]
public String Plot { get; set; }
[JsonProperty(PropertyName = "Poster")]
public String Poster { get; set; }
[JsonProperty(PropertyName = "Metascore")]
public int Metascore { get; set; }
[JsonProperty(PropertyName = "imdbRating")]
public decimal ImdbRating { get; set; }
[JsonProperty(PropertyName = "imdbVotes")]
public int ImdbVotes { get; set; }
}
UPDATE #1 :
How can I handle the response when the property has the value "N/A"?. That happens for some movies (ie. http://www.omdbapi.com/?i=&t=four+rooms has it's Metascore set to N/A).
UPDATE #2 :
Another related inquiry. I'm using EF6 with MySQL and the idea's to populate the database with movies created through JSON parsing.
This is my Movie class :
[JsonObject(MemberSerialization.OptIn)]
[Table("movies")]
public class MovieJSON
{
[Key]
public int Id { get; set; }
[JsonProperty(PropertyName = "Title")]
[Column("title")]
public String Title { get; set; }
[JsonProperty(PropertyName = "Year")]
[Column("year")]
public int Year { get; set; }
[JsonProperty(PropertyName = "Genre")]
[Column("genre")]
public String Genre { get; set; }
[JsonProperty(PropertyName = "Director")]
[Column("director")]
public String Director { get; set; }
[JsonProperty(PropertyName = "Actors")]
[Column("actors")]
public String Actors { get; set; }
[JsonProperty(PropertyName = "Plot")]
[Column("plot")]
public String Plot { get; set; }
[JsonProperty(PropertyName = "Poster")]
[Column("poster")]
public String Poster { get; set; }
[JsonProperty(PropertyName = "Metascore")]
public String Metascore { get; set; }
[Column("metascore")]
public int MetascoreInt
{
get
{
int result;
if (int.TryParse(Metascore, NumberStyles.AllowThousands, CultureInfo.InvariantCulture, out result))
return result;
return 0;
}
}
[JsonProperty(PropertyName = "imdbRating")]
public String ImdbRating { get; set; }
[Column("imdb_rating")]
public Decimal ImdbRatingDecimal
{
get
{
Decimal result;
if (Decimal.TryParse(ImdbRating, out result))
return result;
return 0;
}
}
[JsonProperty(PropertyName = "imdbVotes")]
public String ImdbVotes { get; set; }
[Column("imdb_votes")]
public long ImdbVotesLong
{
get
{
long result;
String stringToParse = ImdbVotes.Remove(ImdbVotes.IndexOf(','), 1);
if (long.TryParse(stringToParse, out result))
return result;
return 0;
}
}
[JsonProperty(PropertyName = "imdbID")]
[Column("imdb_id")]
public String ImdbID { get; set; }
[JsonProperty(PropertyName = "type")]
[Column("type")]
public String Type { get; set; }
public override string ToString()
{
String[] propertiesToIgnore = {"MetascoreInt", "ImdbRatingDecimal", "ImdbVotesLong"};
var sb = new StringBuilder();
PropertyInfo[] properties = GetType().GetProperties();
foreach (PropertyInfo propertyInfo in properties)
{
if (propertiesToIgnore.Contains(propertyInfo.Name))
continue;
sb.AppendLine(String.Format("{0} : {1} ",
propertyInfo.Name, propertyInfo.GetValue(this, null)));
}
return sb.ToString();
}
}
This is my EF6 configuration-context class (I'm ignoring the String fields and instead, using the Helper ones since the database is configured to accept int for Metascore and so on) :
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Entity<MovieJSON>().Ignore(e => e.Metascore).Ignore(e => e.ImdbRating).Ignore(e => e.ImdbVotes);
base.OnModelCreating(modelBuilder);
}
Additional image info :
Object values before insertion into the database (all values are properly set)
Valid XHTML http://imagizer.imageshack.us/v2/800x600q90/689/8x5m.png
Values in the database :
Valid XHTML http://imagizer.imageshack.us/v2/800x600q90/844/nvc5.png
The helper fields (MetascoreInt, ImdbRatingDecimal, ImdbVotesLong) are returning zero, I can't figure out why.
Any help would be mucho appreciated! :)
All the best

You could have two properties: one would be the string property as it comes from IMDB, and the other would be the int property that converts the string one. To convert, you can use the nifty NumberStyles.AllowThousands flag. So you would have
[JsonProperty(PropertyName = "imdbVotes")]
public string ImdbVotes { get; set; }
public int ImdbVotesInt
{
get
{
int result;
if (int.TryParse(ImdbVotes,
NumberStyles.AllowThousands,
CultureInfo.InvariantCulture,
out result))
return result; // parse is successful, use 'result'
else
return 0; // parse is unsuccessful, return whatever default value works for you
}
}

Why can't I send my custom class through my webservice?

I have these classes:
public abstract class CustomField
{
public String Id { get; set; }
public String Name { get; set; }
public String Description { get; set; }
public FieldType Type { get; set; }
public enum FieldType
{
String = 0,
Integer = 1,
Boolean = 2,
List = 3
}
}
public class StringCustomField:CustomField
{
public String Value { get; set; }
public Int32 MinLenght { get; set; }
public Int32 MaxLenght { get; set; }
public StringCustomField()
{
this.Type = FieldType.String;
}
}
public class CustomGroup
{
public String Id { get; set; }
public String Name { get; set; }
public String Description { get; set; }
public List<CustomField> FieldList = new List<CustomField>();
}
When I try to transfer CustomGroup through my webservice I get this error:
The remote server returned an error: NotFound
Serialization is failing when C# tries to transfer my StringField through my CustomField.
What am I doing wrong?
Marc Gravel tell me to do that and i understand the solution but some thing is wrong, no effects, cath the same error!! , help!!
[XmlInclude(typeof(StringCustomField))]
[XmlInclude(typeof(IntegerCustomField))]
[XmlInclude(typeof(BooleanCustomField))]
[XmlInclude(typeof(ListCustomField))]
public abstract class CustomField
{
public String Id { get; set; }
public String Name { get; set; }
public String Description { get; set; }
public FieldType Type { get; set; }
public enum FieldType
{
String = 0,
Integer = 1,
Boolean = 2,
List = 3
}
}

If you are sending subclasses as xml, you will need [XmlInclude]:
[XmlInclude(typeof(StringCustomField))]
public abstract class CustomField
{...}
You can add multiple [XmlInclude(...)] markers for any other subclasses in the model.

List<CustomField> will serialize and deserialize to a CustomField[] if you're using a web service, won't it?

use
public class CustomGroup
{
public String Id { get; set; }
public String Name { get; set; }
public String Description { get; set; }
public List<CustomField> FieldList = new List< StringCustomField >();
}
instead

If i understand you correctly, you should
1. connect your web service to your app
2. use the namespace of the WS, so all the classes will be used from the Proxy
i don't think that the local class will be understood by the remote web serivce correctly, even if you're using the same assembly on both parties
