Why C# requires two double-quotes to print " in case of verbatim string?


Why C# requires two double-quotes to print " in case of verbatim string?

hope this fix your issue If I store a verbatim string, string s=@""Hello""; it should hypothetically parse the string and print "Hello" (taking the " character as a part of the string) ,
So technically, string s=@""Hello""; should print "Hello"
code :
string x = @"start "" end";
let x = @""Hello""
string x = @"1"+"";
Console.WriteLine(@"Foo {0}", "Bar");

it helps some times All the misunderstanding comes from that I'm not familiar with .rc files (I never used C++ before) and how does the developer handle the strings. Don't punch me if my answer looks so untutored. :)
After talking with the relevant developers, it's confirmed to be a mechanism added by the .rc file creators which is used to handle the double quotes in strings.

may help you . My task is to display specified text e.g. "dummy123". But the problem is that I can't use neither " nor ' and even no integers to do something like that. As I know in Java is no preprocessor like , Make an enum
code :
public enum myEnum{
   dummy123
}
public static void main(String [] args){
    String x = Test.dummy123.toString();
    System.out.println(x);
}

hop of those help?
The problem are the parentheses in the echo part, the closing ) in (x86) is considered as the counterpart of the opening ( in front of echo.
code :
if exist "C:\Program Files(x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" (echo C:\Program Files(x86)\Microsoft Visual Studio 14.0\)
rem //                                                                         ^                         ^
rem //                                                                         +opening-----------closing+
if exist "C:\Program Files(x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" echo C:\Program Files(x86)\Microsoft Visual Studio 14.0\
if exist "C:\Program Files(x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" (echo C:\Program Files^(x86^)\Microsoft Visual Studio 14.0\)
if exist "C:\Program Files(x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" (echo C:\Program Files(x86^)\Microsoft Visual Studio 14.0\)
if exist "C:\Program Files(x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" (
    echo C:\Program Files^(x86^)\Microsoft Visual Studio 14.0\
)
if exist "C:\Program Files(x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" (echo C:\Program Files^(x86^)\Microsoft Visual Studio 14.0\) else echo ERROR: file not found!
if exist "C:\Program Files(x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" (
    echo C:\Program Files^(x86^)\Microsoft Visual Studio 14.0\
) else (

I wish this help you We use DefaultContractResolver class which is the part of Newtonsoft.Json.Serialization. The code will look like as below.
Startup.cs
code :
public void ConfigureServices(IServiceCollection services)
    {
      services.AddMvc().AddJsonOptions(opt =>
      {
        if (opt.SerializerSettings.ContractResolver != null)
        {
          var resolver = opt.SerializerSettings.ContractResolver as DefaultContractResolver;
          resolver.NamingStrategy = null;
        }
      });
    }
