使用jquery ajax将数组传递给WebMethod在asp.net中不工作

I am trying to send all gridview records to webmethod using jquery ajax but it is not working. Here is my code

我正在尝试使用jquery ajax将所有的gridview记录发送到webmethod，但它不起作用。这是我的代码

function Save() {
            var TableData = new Array();

            $('[id*=GridView1] tr').each(function (row, tr) {
                TableData[row] = {
                    "Sr"    : $(tr).find('td:eq(0)').text()
                  , "RollNo": $(tr).find('.RollNo').val()
                  , "Name"  : $(tr).find('.Name').val()
                  , "Marks" : $(tr).find('.Marks').val()
                }
            });
                        TableData.shift();
            $.ajax({
                type: "POST",
                url: "TestPage.aspx/SaveData",
                data: "{Data:'" + JSON.stringify(TableData) + "'}",
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                success: function (msg) {
                    alert(msg.d);
                }
            });
            return false;
        }

  [WebMethod]    
    public static string SaveData(List<string> Data)

    }

That must be throwing a 500 inetrnal server error because of type mismatch:-

由于类型不匹配，必须抛出一个500 inetrnal服务器错误:-

 public static string SaveData(string Data)
    {      
       //My Code
        return "Success";
    }

You are passing a JSON string so you should expect the same at server side and then deserialize it into a .Net object.

您正在传递一个JSON字符串，因此您应该期望在服务器端得到相同的结果，然后将其反序列化为. net对象。

Update:

更新:

You can use the JavaScriptSerializer class:-

您可以使用JavaScriptSerializer类:-

public static string SaveData(string Data)
{      
   JavaScriptSerializer json = new JavaScriptSerializer();
   List<GridData> mygridData = json.Deserialize<List<GridData>>(Data);
   return "Success";
}

You are not passing a List<String> first of all from client side, you are passing a javascript object with properties. So to map it in .Net you will have to define an equivalent Type like this:-

您不是在从客户端传递列表首先，您是在传递一个具有属性的javascript对象。所以要在。net中映射它，你需要定义一个类似的类型:-

public class GridData
{
    public string Sr{ get; set; }
    public string RollNo{ get; set; }
    public string Name{ get; set; }
    public string Marks{ get; set; }        
}
