如何在aspx页面上调用非静态C#函数

Question

我想从aspx页面调用一个c#函数，我在下面试过了

 function  DeleteKartItems(callback) {
   $.ajax({
             type: "POST",
             url: 'About.aspx/updatingdatabase',// my function name in c#
             data: '{"username":"' + col1 + '","password":"' + col2 + '","age":"' + col3 + '","city":"' + col4 + '","id":"' + idlast + '"}',
             contentType: "application/json; charset=utf-8",
             dataType: "json",
             success: function (data) {
                              var x = data.d;// i am trying to store the return data into a local variable
             },
             error: function (e) {
             }
         });
     }

我的问题是，当我把c函数写成静态函数时，它工作得很好，但从其他方面来说，它不会工作，我想知道有没有任何方法可以从aspx页面调用非静态的c函数提前感谢

不可能直接通过url从aspx页面运行函数。

尝试以下操作：

1. 更改您的ajax请求如下：

   $.ajax({
        type: "POST",
        url: 'About.aspx',
        data: '{"method":"updatingdatabase","username":"' + col1 + '","password":"' + col2 + '","age":"' + col3 + '","city":"' + col4 + '","id":"' + idlast + '"}',
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function (data) {
                         var x = data.d;// i am trying to store the return data into a local variable
        },
        error: function (e) {
        }
    });
   

2. 更新页面中的Page_Load处理程序：

   protected void Page_Load(object sender, EventArgs e)
   {
       if (!String.IsNullOrEmpty(Request["method"]) && String.Compare(Request["method"], "updatingdatabase", true) == 0)
       {
           UpdatingDatabase(); //run the method
       }
   }

尝试这个

data: '{"method":"updatingdatabase","username":"' + col1 + '","password":"' + col2 + '","age":"' + col3 + '","city":"' + col4 + '","id":"' + idlast + '"}',

而不是

 url: 'About.aspx',
     data: '{"method":"updatingdatabase","username":"' + col1 + '","password":"' + col2 + '","age":"' + col3 + '","city":"' + col4 + '","id":"' + idlast + '"}',

和pageload 中的调用函数
