调用helloWorld的返回值是正确的,调用add的时候,传入(1,2)时,返回值却为0,不知什么原因,这个问题困惑了很久,请高手们指教~
以下是源码
//c#写的webservice的源码
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class servTest : System.Web.Services.WebService { public servTest () { //Uncomment the following line if using designed components
//InitializeComponent();
} [WebMethod]
public string HelloWorld() {
return "Hello World";
}
[WebMethod]
public int add(int a, int b)
{
return a + b;
}
}

我按你的做,也出现问题,提示没指定port,service;
D2006以下WSDL貌似都有乱码 和传入数据出问题的BUG
我以前有个程序就是折腾了半天
procedure TForm1.Button1Click(Sender: TObject);
var
client:variant;
begin
client:=createoleobject('MSSOAP.SoapClient30');
client.clientproperty('ServerHTTPRequest'):= true;
//Client.mssoapinit('http://10.20.10.224/webserive/servTest.asmx?wsdl','servTest','servTestSoap');Client.mssoapinit('http://10.20.10.220/zjdxgc/Service.asmx?wsdl','CheckPassword','CheckPasswordSoap');showmessage(client.XSCheckPassword('0410307444','00000'));
//showmessage(client.add(1,2));end;
