How would I go about testing a complex nested JSON file?

Hello,

I have been tasked to test a complex nested JSON file. The data file is produced by an application. How can I validate the data file with C#?

The JSON data has blocks of arrays and the blocks are not predefined. There are 6 blocks of arrays.

Unfortunately, I cannot upload the file.

All help is appreciated.

Sincerely

Suhas

1. string jsonString = "someString";
2. try
3. {
4. var tmpObj = JsonValue.Parse(jsonString);
5. }
6. catch (FormatException fex)
7. {
8. //Invalid json format
9. Console.WriteLine(fex);
10. }
11. catch (Exception ex) //some other exception
12. {
13. Console.WriteLine(ex.ToString());
14. }

I think you should read json data and assign to a string variable and pass that variable in below code to validate.

public bool IsValidJson(string YourVariable)
{
strInput = strInput.Trim();
if ((strInput.StartsWith("{") && strInput.EndsWith("}")) || //For object
(strInput.StartsWith("[") && strInput.EndsWith("]"))) //For array
{
try
{
var obj = JToken.Parse(strInput);
return true;
}
catch (JsonReaderException jex)
{
//Exception in parsing json
Console.WriteLine(jex.Message);
return false;
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
return false;
}
}
else
{
return false;
}
}
