今天发现,在.NET 3.5下,异步调用Web Service与以往似乎有些不同。现在生成的代理类少了 BeginXXX 方法,Why?
1. Web Service
[WebMethod]
public string GetUserName() {
return "zhenglanzhen";
}
2. 同步调用
class Program {
static void Main(string[] args) {
Console.WriteLine("step1");
NameServiceProxy.NameService n = new NameServiceProxy.NameService();
Console.WriteLine(n.GetUserName());
Console.WriteLine("step2");
Console.Read();
}
}
输出:
step1
zhenglanzhen
step2
3. 异步调用
class Program {
static void Main(string[] args) {
Console.WriteLine("step1");
NameServiceProxy.NameService n = new NameServiceProxy.NameService();
n.GetUserNameCompleted += delegate(object sender, GetUserNameCompletedEventArgs e) {
Console.WriteLine(e.Result);
};
n.GetUserNameAsync();
Console.WriteLine("step2");
Console.Read();
}
}
输出:
step1
step2
zhenglanzhen
