动态执行C#代码示例

 private void button1_Click(object sender, EventArgs e)
        {
            string s = "string s1=\"o\";string s2=\"k\";return s1+s2;";
            Object ret = Execute(s);
            MessageBox.Show(ret.ToString());
            //Console.WriteLine(ret);
            //Console.ReadKey();
        }


        static Object Execute(String code)
        {
            CSharpCodeProvider provider = new CSharpCodeProvider();
            CompilerParameters parameters = new CompilerParameters();
            CompilerResults results = provider.CompileAssemblyFromSource(parameters, BuildCode(code));
            MethodInfo methodInfo = results.CompiledAssembly.GetType("C").GetMethod("T");
            return methodInfo.Invoke(null, null);
        }
        static String BuildCode(String code)
        {
            StringBuilder builder = new StringBuilder();
