将JSON对象从Javascript传递到ASP.Net

Question

我试图将Json字符串sObject从javascript传递给c＃。在c＃中，我试图将此JSon字符串中的数据加载到Object。 我在Javascript中收到错误请求错误。

C＃实体对象：

public class StatusEntity
{
    public string WorkOrderID { get; set; }
    public string JobID { get; set; }
    public string ClientID { get; set; }
}

c＃WCF服务：

[WebInvoke(UriTemplate = "/updatestatus", Method = "POST", BodyStyle = WebMessageBodyStyle.WrappedRequest, ResponseFormat = WebMessageFormat.Json)]
public string updateStatus(List<StatusEntity> _objStatus)
{
    string sResult = string.Empty;
    try
    {
            // SOME CODE HERE
    }
    catch (Exception)
    {
        sResult = string.Empty;
        throw;
    }
    finally
    {

    }
    return sResult;
}

Javascript代码：

function updateStatus() {
    var sObject = '[{"WorkOrderID":"9","JobID":"48","ClientID":"9"},{"WorkOrderID":"9","JobID":"48","ClientID":"10"}]';
    $.ajax({
        cache: false,
        type: "POST",
        async: false,
        url: "../JobMatchingService/updatestatus",
        contentType: "application/json; charset=utf-8",
        dataType: "json",

        // OLD CODE - NOT WORKING
        data: sObject,
        // NEW CODE CHANGES WORKING
        data: '{"_objStatus":' + _objStatus + '}',

        success: function (response) {
            alert(response);
        },
        error: function (xhr, options, error) {
            alert(error);
        }
    });
}

Answer 1

将_objStatus更改为方法参数中的字符串，然后使用try / catch将其转换为StatusEntity，如下所示：

var status = JsonConvert.DeserializeObject<List<StatusEntity>>(jsonString);

Answer 2

对javascript进行了更改，数据必须指定如下：

    // OLD CODE - NOT WORKING
    data: sObject,

    // NEW CODE CHANGES WORKING
    data: '{"_objStatus":' + _objStatus + '}',


function updateStatus() {
    var sObject = '[{"WorkOrderID":"9","JobID":"48","ClientID":"9"},{"WorkOrderID":"9","JobID":"48","ClientID":"10"}]';
    $.ajax({
        cache: false,
        type: "POST",
        async: false,
        url: "../JobMatchingService/updatestatus",
        contentType: "application/json; charset=utf-8",
        dataType: "json",

        // OLD CODE - NOT WORKING
        data: sObject,
        // NEW CODE CHANGES WORKING
        data: '{"_objStatus":' + _objStatus + '}',

        success: function (response) {
            alert(response);
        },
        error: function (xhr, options, error) {
            alert(error);
        }
    });
}
