I have a WebMethod with a parameter defined as DateTime. When I call that

我有一个WebMethod，其参数定义为DateTime。我打电话的时候

webservice, I get this error:

webservice，我收到此错误：

This is my WebService:

这是我的WebService：

/// <summary>
/// Summary description for AgendamentoService
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.Web.Script.Services.ScriptService]
public class AgendamentoService : System.Web.Services.WebService
{

    public AgendamentoService()
    {

        //Uncomment the following line if using designed components 
        //InitializeComponent(); 
    }

    [WebMethod]
    public CompromissoWekCalendarVO[] GetCompromissos(int id_pessoa, DateTime start, DateTime end)
    {
        bo.CompromissoBO compBO = new bo.CompromissoBO();
        return compBO.Get(id_pessoa,start, end).ToArray();
    }

}

And here, my client side code:

在这里，我的客户端代码：

 var params =  '{id_pessoa: "' + id_pessoa + '", start:/Date('+ start.getTime()+')/, end:/Date(' + end.getTime()+')/}';
                    $.ajax(  
                         {  
                             type: "POST",  
                             dataType: "json",
                             contentType: "application/json; charset=utf-8",  
                             url: '<%= this.ResolveClientUrl("~/services/misc/AgendamentoService.asmx/GetCompromissos") %>',  
                             data: params,  
                             success: function (json) {  

                                if ($.isArray(json.d)) {
                                  $.each(json.d, function(key, value) {
                                    value.start = getJsonDate(value.start);
                                    value.end = getJsonDate(value.end);
                                  });
                                }

                                callback(json.d);                                 

                             }  
                         });

Where 'start' and 'end' time are two javascript 'Date' objects.

'开始'和'结束'时间是两个javascript'日期'对象。

Thats because there is specific date/time wire format that ASP.NET Ajax expects - its of form of "\/Date(x)\/", where x is the number of ms elapsed since Jan. 1, 1970 at midnight UTC. So essentially, you need to use some helper function that will convert your JS dates into the needed format while calling the service (and vice versa, date/time json from service to JS date/time object).

这是因为ASP.NET Ajax期望有特定的日期/时间有线格式 - 它的形式为“\ / Date（x）\ /”，其中x是自1970年1月1日UTC午夜以来经过的ms数。所以基本上，你需要使用一些辅助函数，在调用服务时将JS日期转换为所需的格式（反之亦然，日期/时间json从服务到JS日期/时间对象）。

So, you have to change code fragment such as

所以，你必须改变代码片段，如

`'", start:/Date('+ start.getTime()+')/, end...`

至

'", start:"\\\/Date(' + this.getTime() + ')\\\/", end...'

This worked for me:

这对我有用：

JSON.stringify(new Date())

This converts it into a format like "2014-06-04T14:26:27.129Z", which my web service is happy to accept for a DateTime parameter.

这会将其转换为“2014-06-04T14：26：27.129Z”之类的格式，我的Web服务很乐意接受DateTime参数。
