Android调用Asp.net Web Service示例

WebService代码：

    [System.ComponentModel.ToolboxItem(false)]
    // 若要允许使用 ASP.NET AJAX 从脚本中调用此 Web 服务，请取消对下行的注释。
    // [System.Web.Script.Services.ScriptService]
    public class ADWS : System.Web.Services.WebService
    {

        [WebMethod]

        }

        [WebMethod]
        public string GetDate(int t)
        {

            }
            return result;
        }

        [WebMethod]

                Age = new Random().Next(20, 50),
            };
            return p;
        }

        public class Person
        {
            public string Name { get; set; }
            public bool Gender { get; set; }
            public DateTime LogTime { get; set; }
            public int Age { get; set; }
        }
