解决方案

你好朋友，



尝试在网络服务中更改您的Helloworld功能，如下所示：

 [ WebMethod] 
  public   string  HelloWorld（ string  prefixText， int  count）
 {
  return    Hello World; 
} 
 

希望它能解决您的问题。

解决方案

Hi friend,

Try to change your Helloworld function in webservice as follows:

[WebMethod]
public string HelloWorld(string prefixText, int count)
{
    return "Hello World";
}

Hope it will solve your problem.
