动态调用WebService 的相关方法

来源：网络，不过修改了一个小地方，原来的

CSharpCodeProvider csc = new CSharpCodeProvider();
ICodeCompiler icc = csc.CreateCompiler();

会提示已经过时，

现在修改为  CodeDomProvider csc= CodeDomProvider.CreateProvider("CSharp");

调用：

string pcUrl = "http://localhost:8089/test.asmx";
            string pcClassName = "";
            string pcMethodName = "GetData";
            object[] objs =  new object[1];
            objs[0] = "2013";
            DataSet ds = DynamicWebServiceCall.InvokeWebService(pcUrl, pcClassName, pcMethodName, objs) as DataSet;
