本文介绍了一种通过动态编译.NET代码并在运行时创建程序集的方法，并演示了如何利用这种方式来调用WebService。此外，还提供了详细的代码示例，包括如何处理错误和异常。

如果是代码使用方法..

         StringBuilder _Code = new StringBuilder();
            _Code.AppendLine("using System;");
            _Code.AppendLine("namespace TestName");
            _Code.AppendLine("{");
            _Code.AppendLine("public class TestClass");
            _Code.AppendLine("{");
            _Code.AppendLine("public string Test()");
            _Code.AppendLine("{");
            _Code.AppendLine("return /"Test/";");
            _Code.AppendLine("}");
            _Code.AppendLine("}");
            _Code.AppendLine("}");

IList<string> _List = new List<string>();
_List.Add("System.dll");

            Assembly _Assembly = Zgke.Run.GetAssembly.GetCodeAssembly(_Code.ToString(), _List);
            Type _Class =_Assembly.GetType("TestName.TestClass");
            MethodInfo _Method = _Class.GetMethod("Test");

            object _Object = Activator.CreateInstance(_Class);
            object _Returun = _Method.Invoke(_Object, new object[] { });
            MessageBox.Show(_Returun.ToString());

如果是WEBSERVICE 需要WSDL

Assembly _WebServiceAssembly = Zgke.Run.GetAssembly.GetWebServiceAssembly("http://192.168.0.168/TestTSPSubassemblyBase/TelDirectory.asmx?WSDL", "TestTSPSubassemblyBase");
            Type _Type =_WebServiceAssembly.GetType("TestTSPSubassemblyBase.TelDirectory");
            MethodInfo _Method = _Type.GetMethod("GetHello");
            object _Object =Activator.CreateInstance(_Type);

object _ReturnData = _Method.Invoke(_Object, new object[] { });

下面是全部的类
