javascript - 如何在ajax中构建字符串数组并将其传递给asp？

Question

在我的项目中，我想使用ajax来进行JS和ASP之间的通信。但是，我得到了 500 错误。

JS ajax 中的 JSON 字符串:

 {lists: [{'ID': 'a95fed0d-c1e4-45e8-2cd2-e5d7f099a111', 'colour': 'red'}, {'ID': 'a95fed0d-c1e4-45e8-2cd2-e5d7f099a222', 'colour': 'green'}]}

C#:

 [WebMethod]
 public static string GetCurrentTime(List<string> lists)
 {
     return "text string" ;
 }

完整的 AJAX:

var dataJson = "{lists: [{'ID': 'a95fed0d-c1e4-45e8-2cd2-e5d7f099a111', 'colour': 'red'}, {'ID': 'a95fed0d-c1e4-45e8-2cd2-e5d7f099a222', 'colour': 'green'}]}";
     $.ajax({
            type: "POST",
            url: URL,
            data: dataJson ,
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: OnSuccess,
            failure: function (response) {
                alert(response.d);
            }
        });
function OnSuccess(response) {
        console.log(response.d);
    }

尝试使用JSON.stringify如下所示，用一个对象代替 List<string> ,

var dataJson = {lists: [{'ID': 'a95fed0d-c1e4-45e8-2cd2-e5d7f099a111', 'colour': 'red'}, {'ID': 'a95fed0d-c1e4-45e8-2cd2-e5d7f099a222', 'colour': 'green'}]};
     $.ajax({
            type: "POST",
            url: URL,
            data: JSON.stringify(dataJson),
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: OnSuccess,
            failure: function (response) {
                alert(response.d);
            }
        });
function OnSuccess(response) {
        console.log(response.d);
    }

C#

public class Data { 
        public string ID {get;set;}
         public string colour {get;set;}   // This can be renamed into Pascal case here and in the json
       }

[WebMethod]
 public static string GetCurrentTime(List<Data> lists)
 {
     return "text string" ;
 }
