麻烦传递JSON字符串化阵列到PageMethod的

Question

我有传递JSON字符串化阵列麻烦PageMethod的

[{ 
    "StartDate": "3/1/2011", 
    "EndDate": "3/31/2011", 
    "UserId": "8", 
    "DdlViewSelectedValue": "zzz#", 
    "DdlViewSelectedItem": "zzz", 
    "DdlOrgSelectedValue": "8" 
}, { 
    "StartDate": "3/1/2011", 
    "EndDate": "3/31/2011", 
    "UserId": "9", 
    "DdlViewSelectedValue": "zzz#", 
    "DdlViewSelectedItem": "zzz", 
    "DdlOrgSelectedValue": "8" 
}, { 
    "StartDate": "3/1/2011", 
    "EndDate": "3/31/2011", 
    "UserId": "5", 
    "DdlViewSelectedValue": "zzz#", 
    "DdlViewSelectedItem": "zzz", 
    "DdlOrgSelectedValue": "8" 
}, { 
    "StartDate": "3/1/2011", 
    "EndDate": "3/31/2011", 
    "UserId": "13", 
    "DdlViewSelectedValue": "zzz#", 
    "DdlViewSelectedItem": "zzz", 
    "DdlOrgSelectedValue": "8" 
}, { 
    "StartDate": "3/1/2011", 
    "EndDate": "3/31/2011", 
    "UserId": "6", 
    "DdlViewSelectedValue": "zzz#", 
    "DdlViewSelectedItem": "zzz", 
    "DdlOrgSelectedValue": "8" 
}, { 
    "StartDate": "3/1/2011", 
    "EndDate": "3/31/2011", 
    "UserId": "11", 
    "DdlViewSelectedValue": "zzz#", 
    "DdlViewSelectedItem": "zzz", 
    "DdlOrgSelectedValue": "8" 
}] 

当我到这个AJAX请求，“jsonText”包含上述

function GetUserSchedules() {   
     var jsonText = $.toJSON(arrParams); 
     $.ajax({ 
      type: "POST", 
      url: "/myurl/jquery.aspx/GenerateUserSchedules", 
      data: "{" + jsonText + "}", 
      contentType: "application/json", 
      dataType: "json", 
      success: AjaxSucceeded 
      , 
      error: AjaxFailed 
     }); 
    } 

列出的数据

的PageMethod的：

[System.Web.Script.Services.ScriptMethod] 
    [System.Web.Services.WebMethod] 
    public static void GenerateUserSchedules(Data[] data) 
    { 
    //do stuff; will return data but for now, just keeping it like this 
      System.Web.Script.Serialization.JavaScriptSerializer serializer = new System.Web.Script.Serialization.JavaScriptSerializer();  
} 

数据类：

[Serializable] 
public class Data 
{ 
    public DateTime StartDate { get; set; } 
    public DateTime EndDate { get; set; } 
    public int UserID { get; set; } 
    public string ViewSelectedValue { get; set; } 
    public string ViewSelectedItem { get; set; } 
    public string OrgSelectedValue { get; set; } 
} 

每次AJAX请求被发送的误差函数执行。我究竟做错了什么？

这是日期的常见问题。该JavaScriptSerializer预计以下格式的日期，以便成功地解析他们：

{ 
    "StartDate": "\/Date(983401200000)\/", 
    "EndDate": "\/Date(985989600000)\/", 
    "UserId": "8", 
    "DdlViewSelectedValue": "zzz#", 
    "DdlViewSelectedItem": "zzz", 
    "DdlOrgSelectedValue": "8" 
} 

其中983401200000表示自1970年1月1日，以通用标准时间（UTC）的毫秒数。

报价该documentation：

日期目的，JSON表示为 “\ /日期（蜱的数目）\ /”。 刻度数是正数或 负数长整数值，表示 自从午夜01. UTC开始经过的刻度数（毫秒）。

支持的最大日期值是 的MaxValue（12/31/9999下午十一时59分59秒）和 所支持的最低日期值是 MINVALUE（1/1/0001 12:00:00 AM）。
