Question

I have some class ( simple class ) and i want to compile in runtime this class and create ( in runtime ) some dll that will contain this class.

Is there some way to do it ?

Thanks.

Yes, use CSharpCodeProvider.

You can read the sample code for “Snippy” that I used for C# in Depth – it does exactly this sort of thing.

You can ask CSharpCodeProvider to write to a file or build the assembly in memmory.

Sample code:

using System;
using System.CodeDom.Compiler;
using Microsoft.CSharp;

class Test
{
    static void Main()
    {
        var provider = new CSharpCodeProvider();
        var options = new CompilerParameters {
            OutputAssembly = "Foo.dll"
        };
        string source = "public class Foo {}";

        provider.CompileAssemblyFromSource(options, new[] { source });
    }
}
