Json string not valid with errrors

Question

0.00/5 (No votes)

See more:

Below is a Json string
When I pastes it (the 1st and last characters, namely the double quote, are removed) in
JSON Formatter & Validator[^]
for validation.

JsonString = "{\"ownerSysId\":\"MyIMG\",\"applicationId\":31000,\"uploadFiles\":[{\"id\":2121,\"path\":\"\\\\jServer.local\\gisprod\\Photos\\engineering\\A01\\A01\\PF(2)\\2019\",\"fileName\":\"\\E029089_02-21-2019_085353.png\",\"bearing\":\"none\",\"createdDate\":\"2019-01-03T08:59\"},{\"id\":2141,\"path\":\"\\\\jServer.local\\gisprod\\Photos\\engineering\\B02\\B02\\SHFT(VB4)\\2017\",\"fileName\":\"\\C020533_02-28-2019_131017.png\",\"bearing\":\"none\",\"createdDate\":\"2017-04-27T12:37\"}]}";

The errors received are

Strings should be wrapped in double quotes.

Using NotePad to remove all of the single back-slash, the text likes that below:

{"ownerSysId":"MyIMG","applicationId":31000,"uploadFiles":[{"id":2121,"path":"\\\\jServer.local\\gisprod\\Photos\\engineering\\A01\\A01\\PF(2)\\2019","fileName":"\\E029089_02-21-2019_085353.png","bearing":"none","createdDate":"2019-01-03T08:59"},{"id":2141,"path":"\\\\jServer.local\\gisprod\\Photos\\engineering\\B02\\B02\\SHFT(VB4)\\2017","fileName":"\\C020533_02-28-2019_131017.png","bearing":"none","createdDate":"2017-04-27T12:37\"}]}

it gets validated.
I have tried multiple string function to remove single back-slash, but not effective. I will appreciate if you can help for this issue.

What I have tried:

Tried

JsonValue.Replace("\\","")

but not working
Tried

JsonValue.TrimStart('\\').TrimEnd('\\')

but not working

Your final string misses a closing
\"

\"2017-04-27T12:37}]}";

You are right. But added '\"' after \"2017-04-27T12:37 as \"2017-04-27T12:37\"
Still got the error: Strings should be wrapped in double quotes.

Those backslashes don't exist in your string. They only exist in your source code.

Depending on your settings, you might also see them in the debugger.

But if you output the string to the console, you'll see that the string contains perfectly valid JSON:
C# String Escape | C# Online Compiler | .NET Fiddle[^]

C#

string JsonString = "{\"ownerSysId\":\"MyIMG\",...
Console.WriteLine(JsonString);

Output:

{"ownerSysId":"MyIMG",...

Because " and \ have special meaning in C/C++/C# languages, they are escaped when they appear in source code.
Every programming language use this technique to include special chars in a string in source code.
So the json string you see in source code is not what is in executable after compilation.
