我找到了一种更好的方法，可以将AJAX用于来自Controller的源数据.请将此方法用于带有AJAX的DataTable网格:

I found a better way to use AJAX for your source data from the Controller. Please use this method for your DataTable grid with AJAX:

为了在DataTable插件中通过AJAX显示数据，请在代码中进行以下更改:

In order to show your data via AJAX in your DataTable plugin, make the following changes in your code:

添加一个名为DataTable

public class DataTable
{
    public List<vt> data { get; set; }
}

然后在您的控制器中

public JsonResult GetVoters()
{
 DataTable dataTable = new DataTable();
 List<vt> stud = (from student in _context.Voters
                      select new vt
                      {
                          StudentNumber = student.StudentNumber,
                          Name = student.Name,
                          Faculty = student.Faculty,
                          Department = student.Department,
                          Program = student.Program,
                          Code = student.Code
                      }).Take(100).ToList();
    //The magic happens here
    dataTable.data = stud;
    return Json(dataTable, JsonRequestBehavior.AllowGet);
  }

最后在您的View中，使用以下脚本填充您的DataTable:

And finally in your View, use this script to populate your DataTable:

 <script type="text/javascript">
    $(document).ready(function () {

        //For filtering:
        $('#codetable thead tr').clone(true).appendTo('#codetable thead');
        $('#codetable thead tr:eq(1) th').each(function (i) {
            var title = $(this).text();
            $(this).html('<input type="text" placeholder="Search ' + title + '" />');

            $('input', this).on('keyup change', function () {
                if (table.column(i).search() !== this.value) {
                    table
                        .column(i)
                        .search(this.value)
                        .draw();
                }
            });
        });

        var table=$('#codetable').DataTable({
            "ajax": '@Url.Action("GetVoters", "Index")',
            "columns": [
                { "data": "StudentNumber" },
                { "data": "Name" },
                { "data": "Faculty" },
                { "data": "Department" },
                { "data": "Program" },
                { "data": "Code" }
            ]
        });
    });
</script>

而且我几乎忘记了，出于过滤目的，还更改了HTML表的结构:

And I almost forgot, change the structure of your HTML table also for your filtering purpose:

<table class="table table-striped" id="codetable">
        <thead>
            <tr>
                <th>Student Number</th>
                <th>Student</th>
                <th>Faculty</th>
                <th>Department</th>
                <th>Program</th>
                <th>Code</th>
            </tr>
        </thead>
        <tbody></tbody>
</table>

我已将DataTables与 AJAX对象用作网格的数据源.

I have used DataTables with AJAX objects as datasource for your grid.

干杯.
