作为程序一部分在运行时进行代码编译

Question

This code snippet was written to compile the code at run-time. The compiled code works like any other program. Reflection can be accessed with. I want to do a little different things.

using System;
using System.Collections.Generic;
using System.Linq;
using Microsoft.CSharp;
using System.CodeDom.Compiler;

class Program
{
    static void Main(string[] args)
    {
        var csc = new CSharpCodeProvider(new Dictionary<string, string>() { { "CompilerVersion", "v3.5" } });
        var parameters = new CompilerParameters(new[] { "mscorlib.dll", "System.Core.dll" }, "foo.exe", true);
        parameters.GenerateExecutable = true;
        CompilerResults results = csc.CompileAssemblyFromSource(parameters,
        @"using System.Linq;
            class Program {
              public static void Main(string[] args) {
                var q = from i in Enumerable.Range(1,100)
                          where i % 2 == 0
                          select i;
              }
            }");
        results.Errors.Cast<CompilerError>().ToList().ForEach(error => Console.WriteLine(error.ErrorText));
    }
}

For Example :

My Code is Textbox1.Text="123"; it is in a file or in database.

There is a form.A Textbox in form. I want to use string code as part of my program on runtime.

To do this, you can change the function name to string_Function instead of Main. Save the above code snippet as .cs file. Say Code_Snippet.cs. Now add this file to your MainProject. Wherever you want to use this code snippet you have to write line of code eg Code_Snippet.String_Function(TextBox.Text);
