This object fills just fine
[DelimitedRecord("|")]
public class LvMenuItems
{
public string Sequence { get; set; }
public string DisplayText { get; set; }
public string MenuId { get; set; }
public string PageUrl { get; set; }
public string ControlPanelSequence { get; set; }
}
[DelimitedRecord("|")]
public class LvMenuItems
{
public string Sequence { get; set; }
public string DisplayText { get; set; }
public string MenuId { get; set; }
public string PageUrl { get; set; }
public string ControlPanelSequence { get; set; }
[LVMenuItems]
public LVMenutItems menu items {get; set;}
}
Is it possible to embed a copy of the same structure as an attribute of an object to introduce recurrsion?
I was going about this completely wrong. The correct way it to declare a single object that corresponds to the delimited file and then use that object to fill a second object that handles recursion.

i am trying to convert JSON to object following is my json
{"entity":"event","account_id":"acc_8yTsyb2WJOlcka","event":"payment.captured","contains":["payment"],"payload":{"payment":{"entity":{"id":"pay_AKR45WLH0g1ANu","entity":"payment","amount":100,"currency":"INR","status":"captured","order_id":"order_AKR41LsWIgOAB1","invoice_id":null,"international":false,"method":"netbanking","amount_refunded":0,"refund_status":null,"captured":true,"description":"Admission Fees","card_id":null,"bank":"SBIN","wallet":null,"vpa":null,"email":"xxxxx.xxxx#xxx.xxx","contact":"xxxxx","notes":{"address":"NA","merchant_order_id":"2516"},"fee":2,"tax":0,"error_code":null,"error_description":null,"created_at":1528367383}}},"created_at":1528367384}

Have you tried changing:
{"entity":"event","account_id":"acc_8yTsyb2WJOlcka","event":
to
{"entity":"event","account_id":"acc_8yTsyb2WJOlcka","events":
That would better match your class definition. Or rename your class field to event.
There is a useful visual studio function for converting a json object to c# classes.
Copy the JSON into the clipboard. (helps if the JSON object properties holds data, to determine the data type)
Go to visual studio and place cursor where you'd like to paste in the c# classes.
click edit => paste special => paste json as classes
I'm programming a C# implementation for the Qualtrics API (v 2.5) using RestSharp. When calling the method getUserIds, it returns a list of users in JSON format (see the example output below).
The problem/question I face is that for each user object (the list of objects under Result) it generates a different id, starting with URH_. When using json2csharp it assumes ofcourse that it's always a different class, while in fact it's absolutely the same one as you can see in the output, and as is stated in the documentation of the api. How can I best resolve this - so that I can make a class UserData that I can reuse? Because now I obviously always see these random URH_ prefixed classes in each response.
NOTE: I was thinking I could try to massage the response first, and when I get the response replace each URH_ prefixed object under the root Result object with a "UserData" string - but I feel this is breaking the rules a bit, and thought the community would have a better solution?
Below is the raw JSON output (note that I removed sensitive information):
{"Meta":{"Status":"Success","Debug":""},"Result":{"URH_3wpA9pxGbE0c7Xu":{"DivisionID":null,"UserName":"user.name#domain.com","UserFirstName":"x","UserLastName":"x","UserAccountType":"UT_4SjjZmbPphZGKDq","UserEmail":"x.x#x.x","UserAccountStatus":"Active"},"URH_57vQr8MVXgpcPUo":{"DivisionID":"DV_XXXXXXXX","UserName":"jxxxx#xx.xxx","UserFirstName":"X","UserLastName":"X","UserAccountType":"UT_BRANDADMIN","UserEmail":"xxxx#xxg.xxx","UserAccountStatus":"Active"},"URH_6ujW1EP0QJOUaoI":{"DivisionID":"DV_XXXXXXXYZ","UserName":"x.xckx#xxx.xyz","UserFirstName":"x","UserLastName":"x","UserAccountType":"UT_XXXXXABCD","UserEmail":"c.c#cc.com","UserAccountStatus":"Active"}}}
This is what I get when generating a model using json2csharp:
public class Meta
{
public string Status { get; set; }
public string Debug { get; set; }
}
public class URH3wpA9pxGbE0c7Xu
{
public object DivisionID { get; set; }
public string UserName { get; set; }
public string UserFirstName { get; set; }
public string UserLastName { get; set; }
public string UserAccountType { get; set; }
public string UserEmail { get; set; }
public string UserAccountStatus { get; set; }
}

}
public class Result

}
public class RootObject
{
public Meta Meta { get; set; }
public Result Result { get; set; }
}
It's simple - just use Dictionary<string, UserData> generic type for Result field:
public class Response
{
public Meta Meta { get; set; }
public Dictionary<string, UserData> Result { get; set; }
}
public class Meta
{
public string Status { get; set; }
public string Debug { get; set; }
}
public class UserData
{
public string DivisionID { get; set; }
public string UserName { get; set; }
public string UserFirstName { get; set; }
public string UserLastName { get; set; }
public string UserAccountType { get; set; }
public string UserEmail { get; set; }
public string UserAccountStatus { get; set; }
}
I am new to C#. I have successfully consumed the Mailchip API with a simple console app. I am pulling in relevant data and I have successfully used a JSON deserializer on the returned data (Newtonsoft.Json via NuGet). What I need to find is the best way to place the data into variables which I can then pass to a stored procedure to save the data. I know SQL and I know how to pass variables to a stored procedure in C# (connection strings and such).
What I don't know is how to parse through the deserialized data and then place each value into a variable or something I can pass to SQL. I know this is a vague question so here is the current code.

So for each member (0-3), I need to pull each fields value (Field names in bold) into a variable and save it to a database. I just don't know how to parse through each member.
I know this is a long question for a simple C# problem, but if you can remember way back to the beginning of the post I stated "I am new to C#"
Thanks in advance.
I have the following data structure
public class Prediction
{
public string Description {get;set;}
public string Id { get; set; }
public List<MatchedSubstring> Matched_substrings { get; set; }
public string Place_id { get; set; }
public string Reference { get; set; }
public List<Term> Terms { get; set; }
public List<string> Types { get; set; }
}
public class GooglePlaceAutocompleteResult
{
public List<Prediction> Predictions { get; set; }
public string Status { get; set; }
}
What I would like to do is remove any items in the Predictions list if their Types collection contains the string "sublocality".
How can I do this with LINQ?
Assuming you are writing a method within GooglePlaceAutocompleteResult, you can write:
Predictions = Predictions.Where(p => !p.Types.Any(t => t.Contains("sublocality")).ToList();
Otherwise the code would be the same but would be result.Predictions = result.Predictions...

//getting here error below line: Object ref notset to instance of object
lblfmiVersion.Text = resobj.fmi.invalid_nameattribute.version;
Any Idea?
If you're getting Object Reference not set to an instance of object. that means that you're trying to access properties on an object that is null. Since you said it happens on this line:
lblfmiVersion.Text = resobj.fmi.invalid_nameattribute.version;
that could mean that any of resobj, resobj.fmi, or resobj.fmi.invalid_nameattribute are null. Ignoring the fact that you should have proper null checks in your code to help avoid this situation, let's ask the question, why would any of these objects be null if deserialization succeeded? Perhaps some of the data was not deserialized correctly after all.
When deserializing using Json.Net, it is important to know that if any members of a class do not have matching properties in the JSON, those members will be skipped by Json.Net and thus retain their default values, e.g. null. So one possible reason that you have a null is that the name of a property in your class does not match what is in the JSON.
If we take a look at your Fmi class, one thing that jumps out right away is that it has a suspiciously named property called invalid_nameattribute. In the JSON, there is no such property. Instead, there is a property called #attributes. Your FmipLockStatusDevice class has the same problem. Since they didn't match up, these properties did not get populated during deserialization, so they are null.
So how can we fix this?
This is simple enough: add a [JsonProperty] attribute to your class properties to map them to the right JSON properties. (While you're at it, you might also consider changing the names of those properties in your C# class to something that actually makes sense, like "Attributes".)
public class Fmi
{
[JsonProperty("#attributes")]
public Attributes invalid_nameattribute { get; set; }
public FmipLockStatusDevice fmipLockStatusDevice { get; set; }
}
public class FmipLockStatusDevice
{
[JsonProperty("#attributes")]
public Attributes2 invalid_nameattribute2 { get; set; }
}
OK, now that you have a solution, you should ask yourself, how did you get into this situation in the first place, and how can you avoid it in the future?
You said you used json2csharp.com to generate your classes. You need to be aware that this tool is not foolproof, and will not always be able to generate correct classes to work with your JSON. This is true whenever the JSON property names contain punctuation characters or spaces or start with numbers, because these cannot be turned into valid C# property names. In these cases, json2csharp.com will generate a property name that starts with "invalid". You need to look for these, and make manual adjustments to your classes to fix the issues. Do not just blindly use the generated classes and assume they are correct.
Hope this helps.
