使用“ application / json;将ajax发布到mvc; charset = utf

最终成功了：

    var filtersApplyData = GetFiltersApplyData@(Model.PropertyID)();    var data = JSON.stringify({data: filtersApplyData, classID: @(Model.ClassID)});    $.ajax({  type: "POST", url: "@Url.Action("ApplyFilters", "Grid")", data: data,  contentType: "application/json",  traditional: true, success: function (data) {      $("#grid").html(data); }, error:function (xhr, ajaxOptions, thrownError) {      alert(xhr.status);      alert(ajaxOptions);      alert(thrownError);  }    });
