WebService重载问题
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1 )]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
// [System.Web.Script.Services.ScriptService]
public class WebService : System.Web.Services.WebService {
public WebService () {
//Uncomment the following line if using designed components
//InitializeComponent();
}
[WebMethod]
public string HelloWorld() {
return "Hello World";
}
[WebMethod]
public string HelloWorld(string str)
{
return "Hellp World,"+str;
}
}
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1 )]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
// [System.Web.Script.Services.ScriptService]
public class WebService : System.Web.Services.WebService {
public WebService () {
//Uncomment the following line if using designed components
//InitializeComponent();
}
[WebMethod]
public string HelloWorld() {
return "Hello World";
}
[WebMethod]
public string HelloWorld(string str)
{
return "Hellp World,"+str;
}
}
在浏览器中查看，会报如下错误
修改步骤如下：
1.修改[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1 )]，为[WebServiceBinding(ConformsTo = WsiProfiles.None )]；
2.为重载的各方法添加不同的MessageName属性，作为重载时的标识。
[WebMethod(MessageName ="ShowWithoutName",Description="直接输出HelloWorld")]
public string HelloWorld() {
return "Hello World";
}
[WebMethod (MessageName ="ShowByName",Description="输出指定的字符串")]
public string HelloWorld(string str)
{
return "Hellp World,"+str;
}
public string HelloWorld() {
return "Hello World";
}
[WebMethod (MessageName ="ShowByName",Description="输出指定的字符串")]
public string HelloWorld(string str)
{
return "Hellp World,"+str;
}
3.再次重新生成后，查看结果如下
