Create dll file in runtime doesn't work in c#

I am trying to create a DLL file in runtime ,as a matter of fact i need to save an encoded data to DLL .My code is like this :

 class DllFile
    {
        public static void CreateDllFile(string source)
        {
            var provider = new CSharpCodeProvider();
            var options = new CompilerParameters
            {
                OutputAssembly = "test.dll"
            };

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

I expect from this code to create a dll file but it doesn't create 

The error is :The pointer for this method was null

Best regards.Any ideas will be appreciated.

Any errors would be in the Errors property of the CompilerResults returned from the CompileAssemblyFromSource method. Have you tried printing them out to see if there are errors ?

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

foreach(CompilerError error in results.Errors)
{
      Console.WriteLine(error.ToString());
}

Compilation errors are reported via the returned value:

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

Now check results, and in particular results.Errors.

You can also check results.NativeCompilerReturnValue - that should be 0 for success, and non-zero for failure.
