Can I expand a string that contains C# literal expressions at runtime

by

Similar to Mikael answer but using the CSharpCodeProvider:

    public static string ParseString(string txt)
    {
        var provider = new Microsoft.CSharp.CSharpCodeProvider();
        var prms = new System.CodeDom.Compiler.CompilerParameters();
        prms.GenerateExecutable = false;
        prms.GenerateInMemory = true;
        var results = provider.CompileAssemblyFromSource(prms, @"
namespace tmp
{
    public class tmpClass
    {
        public static string GetValue()
        {
             return " + "\"" + txt + "\"" + @";
        }
    }
}");
        System.Reflection.Assembly ass = results.CompiledAssembly;
        var method = ass.GetType("tmp.tmpClass").GetMethod("GetValue");
        return method.Invoke(null, null) as string;
    }

You might be better off using a dictionary of wildcards and just replacing them in the string.
