我正在尝试使用 ajax 回传将 javascript 数组传递给 C# 代码。但是当我尝试这个时它没有用。我在下面附上了我的代码。有人可以帮我吗？

测试.aspx

    function testbook(hotelcode) {

        //var values = {"1","2","3"};
        var mycars = new Array();
        mycars[0] = "Saab";
        mycars[1] = "Volvo";
        mycars[2] = "BMW";
        var theIds = JSON.stringify(mycars);
        alert(theIds);
        $.ajax({
            type: "POST",
            url: "test.aspx/Done",
            contentType: "application/json; charset=utf-8",
            data: "{ 'ids':'"+ theIds +"'}",
         dataType: "json",
         success: function (result) {
             alert('Yay! It worked!');               
         },
         error: function (result) {
             alert('Oh no :(');
         }
        });


        return false;

    }

        {
            ImageButton testbtn = new ImageButton();
            testbtn.OnClientClick = "return testbook('15000')";
            form1.Controls.Add(testbtn);

        }

        [WebMethod]
        public static void done(string[] ids)
        {
            String[] a = ids;

        }


    }
}

当我如下更改网络方法时，它没有任何问题。但这对我没有用。

  [WebMethod]
        public static void done(string ids)
        {
            String a = ids;

        }

Try this. I've had success passing javascript arrays as such. The only limitation is that an object with the params keyword must be the last argument passed to the web method.

http://msdn.microsoft.com/en-us/library/w5zay9db.aspx

[WebMethod]
public static void PassArray(params object[] list)
{
    int i = 0;
    while (i < list.Length)
    {
        //do your thing here
        i++
    }
}

尝试这个

    [WebMethod]
    public static void done(List<string> ids)
    {
        String[] a = ids.ToArray();

    }

错误的json格式：

"{ 'ids':'"+ theIds +"'}"

使用双引号。或者做得更好：

JSON.stringify({ ids: mycars });
