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

Question

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

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 ; } }

string jsonString = "someString" ; try { var tmpObj = JsonValue.Parse(jsonString); } catch (FormatException fex) { //Invalid json format Console.WriteLine(fex); } catch (Exception ex) //some other exception { Console.WriteLine(ex.ToString()); }
