C# WebForms-使用jQueryAjax传递复杂的对象数组

我想传递一个复杂的对象数组，evrey对象还有另外两个对象数组

例如：

 [{"Item":{"ClientId":"2","Projects":[{"ProjectId":"81","TypeId":"8"}],"Types":[{"ProjectType":"2","ProjectName":"yty - موقع2 - aaaaaaaa"},{"ProjectType":"6","ProjectName":"yty - موقع - aaaaaaaa"}]}},{"Item":{"ClientId":"7","Projects":[{"ProjectId":"75","TypeId":"8"},{"ProjectId":"76","TypeId":"8"}],"Types":[{"ProjectType":"2","ProjectName":"mona - موقع2 - aaaaaaaa"}]}}]

jquery代码：

      $("#btnSave").click(function () {
            var array = [];
            var donatorId = $('.ddlDonators').val();

            $.each($('.cbxClient:checked'), function () {
                var obj = new Object();
                var item = new Object();
                var projectArray = [];
                var projTypeArray = [];
                var attrId = $(this).attr('id');
                var clientId = attrId.split('_')[1];

                $.each($('.formPnl').find('.' + attrId).find('li .Project:checked'), function () {
                    var projObj = new Object();
                    projObj.ProjectId = $(this).val();
                    projObj.TypeId = $(this).attr('ProjectType');
                    projectArray.push(projObj);
                });

                $.each($('.formPnl').find('.' + attrId).find('li .ProjectType:checked'), function () {
                    var projTypeObj = new Object();
                    projTypeObj.ProjectType = $(this).val();
                    projTypeObj.ProjectName = $(this).attr('name') + " - " + $('.ddlDonators option:checked').text();
                    projTypeArray.push(projTypeObj);
                });

                obj.ClientId = attrId.split('_')[1];
                obj.CProject = projectArray;
                obj.Types = projTypeArray;
                item.Item = obj;
                array.push(item);

                //ProjectType = $('.formPnl').find('.' + attrId).find('li .ProjectType:checked').val();
                //ProjectName = $('.formPnl').find('.' + attrId).find('li .ProjectType:checked').attr('name') + " - " + $('.ddlDonators option:checked').text();
                //ProjectId = $('.formPnl').find('.' + attrId).find('li .Project:checked').val();
                //ProjectType = $('.formPnl').find('.' + attrId).find('li .Project:checked').attr('ProjectType');

            });

            $.ajax({
                type: "POST",
                url: "Default.aspx/SaveProjects",
                traditional :true,
                data: "{'DonatorId':'" + donatorId + "','Items':'" + JSON.stringify(array) + "'}",
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                success: function (data) {

                },
                error: function (data) {
                    alert('error')
                    //  alert(data.responseText)
                }
            });  // end of ajax  


            console.log(JSON.stringify(array));
        });

C代码：

[WebMethod]
public static void SaveProjects(int DonatorId, List<Item> Items)
{


}


public class Item
{
    public int ClientId { get; set; }
    public List<CProject> Projects { get; set; }
    public List<Type> Types { get; set; }
}

public class CProject
{
    public int ProjectId { get; set; }
    public int TypeId { get; set; }
}
public class Types
{
    public int ProjectType { get; set; }
    public string ProjectName { get; set; }
}

问题是，在调试过程中，我发现项目的计数是2，但其中的prop=null

提前谢谢

我已经做了这件事 首先，您必须更改将列表转换为字符串的参数，因为您要通过stringify将json数组传递到字符串中

然后反序列化对象主数组并通过以下代码查找嵌套数组

  [WebMethod]
 public static void SaveProjects(int DonatorId, String MainArray)
 {

  Dictionary<string, dynamic> mainDictionary = (Dictionary<string, dynamic>)deserializer.DeserializeObject(MainArray);

 Dictionary<string, object> masterData = mainDictionary["SubArray"] as Dictionary<string, object>;

 object[] objNestedarray= masterData ["NestedArrayName"] as object[];

  }

希望以上代码能帮助您得到解决方案

实际上是我的错，客户端的数组结构与服务器端不一样，所以映射失败，所以我只是在客户端对item对象进行了注释

$("#btnSave").click(function () {
            var array = [];
            var donatorId = $('.ddlDonators').val();

            $.each($('.cbxClient:checked'), function () {
                var obj = new Object();
               // var item = new Object();
                var projectArray = [];
                var projTypeArray = [];
                var attrId = $(this).attr('id');
                var clientId = attrId.split('_')[1];

                $.each($('.formPnl').find('.' + attrId).find('li .Project:checked'), function () {
                    var projObj = new Object();
                    projObj.ProjectId = $(this).val();
                    projObj.TypeId = $(this).attr('ProjectType');
                    projectArray.push(projObj);
                });

                $.each($('.formPnl').find('.' + attrId).find('li .ProjectType:checked'), function () {
                    var projTypeObj = new Object();
                    projTypeObj.ProjectType = $(this).val();
                    projTypeObj.ProjectName = $(this).attr('name') + " - " + $('.ddlDonators option:checked').text();
                    projTypeArray.push(projTypeObj);
                });

                obj.ClientId = attrId.split('_')[1];
                obj.CProject = projectArray;
                obj.Types = projTypeArray;
               // item.Item = obj;
                array.push(obj);


            });

            $.ajax({
                type: "POST",
                url: "Default.aspx/SaveProjects",
                traditional :true,
                data: "{'DonatorId':'" + donatorId + "','Items':" + JSON.stringify(array) + "}",
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                success: function (data) {

                },
                error: function (data) {
                    alert('error')
                    //  alert(data.responseText)
                }
            });  // end of ajax  


            console.log(JSON.stringify(array));
        });

服务器端：

   [WebMethod]
public static void SaveProjects(int DonatorId, List<Item> Items)
{


}



public class Item
{
    public int ClientId { get; set; }
    public List<CProject> CProject { get; set; }
    public List<Types> Types { get; set; }
}

public class CProject
{
    public int ProjectId { get; set; }
    public int TypeId { get; set; }
}
public class Types
{
    public int ProjectType { get; set; }
    public string ProjectName { get; set; }
}

你说的道具在里面是什么意思，如果你把你的结果贴出来会更好debug@SonerGönül，我的意思是项目的计数是2，这是正确的，但是属性的值是空的，例如ClientId=0，其他的为null！！！
