It needs to be compiled. C# is not a scripting language [^]

there must be a way to do this! for example: textbox1.text="button1.backcolor=system.drawing.color.red" how will it become red???

I think you can take the text that user written in your new language and translate into C#, then write it to a .cs file and compile it with csc.exe. CSharp Compiler is available in every machine which has .NET Framework installed in it. And of course user will have .NET Framework installed. OR You can use Microsoft.CSharp.CSharpCodeProvider to compile and run code in real-time. Run-Time Code Generation I: Compile C#-Code using Microsoft.CSharp and System.CodeCom.Compiler[^]

I researched about this topic a little and written a program which is I think enough for you to understand how CodeProvider works. Just run the project and enter

using System;
using System.Collections.Generic;
using System.Text;

namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("IS IT WORKING!!");
Console.ReadLine();
}
}
}

to the textbox. Then press Generate. The compiled executable will be in the same direcory as your program is, as "product.exe" http://rapidshare.com/files/227199842/RealTime_Csharp_Code_Compiler.rar[^] Let me know what you think.

Use a struct that would essentially be a look up table.

struct ColorStruct
{
public Color setColor

public ColorStruct(string input)
{
switch(input){
case "system.drawing.color.red"
setColor = Color.red
break;
...
...
...
}
}
}
