I am able to convert my nested dictionary to json but in attempting to use Json.Net.JsonNet.Deserialize<SortedDictionary<string, dynamic>>(js) it causes a null reference exception where js is loaded from a file containing: "{"Table":{"RowEntries":{}}}". Not sure what to do from here.
here is code to those it may concern:
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
if (openFileDialog1.FileName != "" && openFileDialog1.FileName.EndsWith(".fdb"))
{
defaultPath = openFileDialog1.FileName;
js = #File.ReadAllText(openFileDialog1.FileName);
Console.WriteLine(js);
SortedDictionary<string, dynamic> cd;
try
{
cd = Json.Net.JsonNet.Deserialize<SortedDictionary<string, dynamic>>(js);
DatabaseFunct.currentData.Concat(cd);
//load tables
string[] mainTableKeys = DatabaseFunct.GetMainTableKeys();
foreach (string mainTableKey in mainTableKeys)
{
Program.mainForm.tabControl1.TabPages.Add(mainTableKey, mainTableKey);
}
//fileName = openFileDialog1.FileName.Remove(openFileDialog1.FileName.Length-4, openFileDialog1.FileName.Length);
Program.mainForm.label1.Visible = false;
//triggers event
Program.mainForm.tabControl1.SelectedIndex = 0;
}
catch(Exception e)
{
System.Windows.Forms.MessageBox.Show(e.Message);
}
}
else
{
System.Windows.Forms.MessageBox.Show("no valid file selected!");
}
}
Edit:
Was using the wrong Json.net package instead of the newtonsoft one.
Not sure what you are trying to achieve exactly, but based on provided json this should work:
class MyClass
{
public dynamic RowEntries { get; set; }
}
JsonNet.Deserialize<Dictionary<string, MyClass>>("{\"Table\":{\"RowEntries\":{}}}")

So I'm trying to figure out how to build a Console Application in C# that essentially mimics google maps. I need to be able to enter an address (even if I abbreviate a word. EX: Silverbell Dr) and output the correct spelling (Silverbell Drive).
The goal here is to be able to enter an address in the search, even if the address spelling is incorrect, and output a value that is close enough to the user input that it won't send back a null value.
If anyone has anything that is similar to this, I would greatly appreciate the help!
Boss gave me this assignment knowing that I hardly have a base knowledge on the subject
One way to do it would be to use Googles geocode API. You can pass it a partial address and it will do it's best to return the normalized address for you. If the address isn't very specific, you will get back more than one.
Here's a code example for calling the API and parsing the results:
private static List<string> GetNormalizedAddresses(string address)
{
// Generate request Uri
var baseUrl = "http://maps.googleapis.com/maps/api/geocode/xml";
var requestUri = $"{baseUrl}?address={Uri.EscapeDataString(address)}&sensor=false";
// Get response
var request = WebRequest.Create(requestUri);
var response = request.GetResponse();
var xDoc = XDocument.Load(response.GetResponseStream());
var results = xDoc.Element("GeocodeResponse")?.Elements("result").ToList();
var normalizedAddresses = new List<string>();
// Populate results
if (results != null)
{
normalizedAddresses.AddRange(results
.Select(result => result.Element("formatted_address")?.Value)
.Where(formattedAddress => !string.IsNullOrWhiteSpace(formattedAddress)));
}
return normalizedAddresses;
}
Then, you could call it like so:
while(true)
{
Console.Write("Enter a partial address: ");
var partialAddress = Console.ReadLine();
Console.WriteLine(new string ('-', 25 + partialAddress.Length));
var normalizedAddress = GetNormalizedAddresses(partialAddress);
if (!normalizedAddress.Any())
{
Console.WriteLine("Sorry, couldn't find anything.");
}
else
{
Console.WriteLine("That address normalizes to:");
Console.WriteLine($" - {string.Join($"\n - ", normalizedAddress)}");
}
Console.WriteLine("\n");
}
Output

I get response string "true" from php file...
but ,my function always return false ... here is piece of code
public Boolean authorization(String korisnik, String zaporka) {
using (var client = new WebClient())
{
var values = new NameValueCollection();
values["korisnik"] = korisnik;
values["zaporka"] = zaporka;
var response = client.UploadValues("http://localhost/projectX/autorizacija.php", values);
String responseString = Encoding.Default.GetString(response);
System.Diagnostics.Debug.WriteLine(responseString);
if (responseString.Equals("true"))
{
return true;
}
else
{
return false;
}
}
}
Try:
if (responseString.Trim().Equals("true", StringComparison.InvariantCultureIgnoreCase))
{
return true;
}
else
{
System.Diagnostics.Debug.WriteLine(responseString);
return false;
}
InvariantCultureIgnoreCase = compares strings in a linguistically relevant manner that ignores case
Trim = remove whitespaces
And if false, check output value

I have this code:
//other streamreader code
var splitsByLine = content.Split('\n');
foreach (var s in splitsByLine)
{
var nameAndSize = s.Split(',');
FileNameAndSizes.Add(nameAndSize[0], Convert.ToInt64(nameAndSize[1]));
}
foreach (var item in FileNameAndSizes)
{
if(File.Exists(Path.Combine(Directory.GetCurrentDirectory(), "cleo", item.Key)))
{
FileInfo f = new FileInfo(Path.Combine(Directory.GetCurrentDirectory(), "cleo", item.Key));
var s1 = f.Length;
if (s1 != item.Value)
{
MessageBox.Show(f.Name + " modified file, please change it to default");
}
}
}
When I run code, i have error in this code:
FileNameAndSizes.Add(nameAndSize[0], Convert.ToInt64(nameAndSize[1]));
Index was outside the bounds of the array. and something about 0x0.. I'm C# newbie, how can i fix it?
It's content value:
AnimModByxXx2o1o.cs, 18616
anims.cs, 18780
Dance.cs, 18661
emergencylights.cs, 32213
fps-de-limiter.cs, 17575
neon.cs, 19019
StreamMemFix.cs, 17560
sun.cs, 17662
WEATHERMENUE.cs, 18437
anim.cs, 17637
anim[0].cs, 20684
anim_0_.cs, 19392
anim1.cs, 18744
anim2.cs, 19012
Anim4.cs, 22900
anim228.cs, 19465
P.S I'm tested it with two files:
First file (current) is getting value from mysql, prints it, and then I need to read value with C# app
Second file (working) is create custom file write to it this content, and it's work ok :?
You need to do simple tests to ensure your values before try to work with them:
http://ideone.com/Iyle5C
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
public class Test
{
public static void Main()
{
//other streamreader code
string[] splitsByLine = new string[] { "AnimModByxXx2o1o.cs, 18616",
"anims.cs, 18780",
"Dance.cs, 18661",
"emergencylights.cs, 32213",
"fps-de-limiter.cs, 17575",
"neon.cs, 19019",
"StreamMemFix.cs, 17560",
"sun.cs, 17662",
"WEATHERMENUE.cs, 18437",
"anim.cs, 17637",
"anim[0].cs, 20684",
"anim_0_.cs, 19392",
"anim1.cs, 18744",
"anim2.cs, 19012",
"Anim4.cs, 22900",
"anim228.cs, 19465",
"" };
if (splitsByLine != null && splitsByLine.Any()) // Test
{
foreach (string s in splitsByLine)
{
var nameAndSize = s.Split(',');
if (nameAndSize != null && nameAndSize.Any() && nameAndSize.Count() > 1) // Test
{
Console.WriteLine(String.Concat(nameAndSize[0], " - ", Convert.ToInt64(nameAndSize[1])));
//FileNameAndSizes.Add(nameAndSize[0], Convert.ToInt64(nameAndSize[1]));
}
}
}
}
}

I am using ASP.Net web api for my service, that is called from a third party application. When I test it in chrome postman it works fine in localhost and deployed server, but I have tried it in fiddler, hurl it and the string val is always null, should I be adding something else? I cant understand why it works fine in postman! Going kinda crazy with this one !
Thanks in advance
public bool PostProperty([FromBody] string val)
{
try
{
var reader = new StringReader(val);
var serializer = new XmlSerializer(typeof(property));
var instance = (property)serializer.Deserialize(reader);
}
}
Change your signature to be
public async Task<bool> PostProperty()
{
try
{
var reader = new StringReader(await Request.Content.ReadAsStringAsync());
var serializer = new XmlSerializer(typeof(property));
var instance = (property)serializer.Deserialize(reader);
}
}
or
public bool PostProperty([FromBody] property val)
{
}
If you do the second option, you might have to add the following line to your setup,
config.Formatters.XmlFormatter.UseXmlSerializer = true;
