using System.CodeDom.Compiler;
using Microsoft.CSharp;
 
class Test
{
    public static void Main(string[] args)
    {
        var compiler = new CSharpCodeProvider();
        var parameters = new CompilerParameters { 
            CompilerOptions = "/unsafe"
        };
        var source = "unsafe struct Foo {}";
        var result = compiler.CompileAssemblyFromSource(parameters, source);
        // No errors are shown with the above options set
        foreach (var error in result.Errors)
        {
            Console.WriteLine(error);
        }
    }
}
