推荐答案

你可以返回对象，创建如下所示的类

you can return object, create class like below

public class Results
{
   public string Message {get; set;}
   public int Value {get; set;}
}

then

then

[WebMethod]
 public Results  add( int a, int b)
 {
     Results res new Results();  
     if (a > b)
     {
         res.Message ="a is grater than b";
     }

     res.Value = a + b;
     return res;
 }

致电

when you call

localhost.Service1 client = new localhost.Service1();
int a = int.Parse(TextBox1.Text);
int b = int.Parse(TextBox2.Text);
var res = client.add(a, b);
LabelValue.Text = "Add Result : " + res.Value;
LabelMessage.Text = "Add Message : " + res.Message;

[WebMethod]
 public String add( int a, int b)
 {
   String res="";
     if (a > b)
     {
         res="a is grater than b";
     }
     return res;
 }

您可以使用SOAP FAULT消息抛出异常。 请参阅有关肥皂故障的文章
