javascript - 使用 AJAX 处理以 NULL C# 和 JS 形式出现的 ID 数组

Question

我试图从服务器端的字符串中获取数组，但我正在等待的 ID 为 NULL。请就上面提供的源代码提出建议。我不确定如何在 CompareReturnAllResults(.....) 的范围内处理它们。

    function compareFilesResult(whlIDs) {
    var result = 0;
    $.ajax({
        url: '/ajax/CompareReturnAllResults',
        contentType: "application/json; charset=utf-8",
        type: 'GET',
        dataType: "json",
        data: { ID: whlIDs },
        success: function (data) {
            if (data != null) {
                return result;
            }
        },
        error: function (data) {
            return result;
        },
        fail: function (data) {
            return result;
        }
    });
}





    [HttpGet]
    public ActionResult CompareReturnAllResults(string [] _IDs)
    {
        List<Common.Utilities.CompareFilesResult> result = new List<Common.Utilities.CompareFilesResult>();
        foreach (var id in _IDs)
        {
            var whl = WHLConfig.Caches.WHLsCache.Where(w => w.ID == id).First();
            var diffResponse = WhlObjects.WHLMethods.CompareConfigs(whl);
            Common.Utilities.CompareFilesResult temp = new Common.Utilities.CompareFilesResult(whl.ID, diffResponse.CountDeleted, diffResponse.CountInserted);
            result.Add(temp);
        }  
        string diff = string.Empty;
        if (result != null && result.Count != 0)
        {
            return Json(result, JsonRequestBehavior.AllowGet);
        }
        else
        {
            return Json(string.Empty, JsonRequestBehavior.AllowGet);
        }
    }

我认为我需要将 traditional 设置为 true。

脚本:-

jQuery.ajaxSettings.traditional = true

第一个:-

 $.ajax({
       url: 'controller/GetArray',
       data: JSON.stringify({
          employee: arrEmployee
       }),
       success: function(data) { /* Whatever */ }
    });


****Second One:-****

$.ajax({
     type: "POST",
     url: "controller/GetArray",
     data: {employee: arrEmployee},
     success: function (data) { /* Whatever */  }
});

型号:-

public class Employee
{
  public int Id;
  public string Name;
}

在 Controller 中:-

public ActionResult GetArray(Employee[] employee)
{
    // code here what u do
}

希望它的工作!!
