C# mutiline code string interpolation not working [closed]

Question

I'm trying to add some code to a code string like this

        public static string Compile(string code)
        {
            Write("compiler called.");
/////////////Below is the string I want to interpolate//////////////
            
            string codeToCompile = $@"
            using System;

            namespace RoslynCompileSample
            {
                public class Writer
                {
                    public string Write()
                    {
                        
                        {code}
                    }
                }
            }";
///////////////// Other Codes...//////////////////////////

I've tried to use $@ but still not recognized as a string:

There are two things to mention here:

1. Assignment of code is done incorrectly

2. You have to escape the { and } characters within the interpolated string (Read the special characters section of the docs)
   (if you want to use a " too (in an verbatim string with @, you have also double it to "" to get one), e.g. string code = @"Console.WriteLine(""Helloworld"");";

string code = "Console.WriteLine(\"Helloworld\");";
string codeToCompile = $@"using System;

namespace RoslynCompileSample
{{
    public class Writer
    {{
        public string Write()
        {{
            var code = {code}
        }}
    }}
}}";
