c# - 请求在 Helper 方法上被中止 : The connection was closed unexpectedly.

Question

尝试读取帮助器方法时，我收到“请求已中止:连接意外关闭”错误。

下面是 Index.cshtml 中的代码

@Helper.InsufficientRightsDataBoundScript(!user.HasAccessToBuisnesses, "Insufficient rights to view this page.")

helper.cs

@helper InsufficientRightsDataBoundScript(bool noAccessToRecords, string defaultMessage, string methodSuffix = "")
{
    <script language="javascript">
        @{
            var x = "function OnDataBound"+ (string.IsNullOrEmpty(methodSuffix) ? string.Empty : "_") + methodSuffix+"(e) {";
            @x;
        }

        var grid = e.sender;
        if (grid.dataSource.total() === 0) {

            var filter = grid.dataSource.filter();
            var msg = (filter && filter.filters.length > 0) ? "No rows match the filter criteria." : "@defaultMessage";
            var colCount = grid.columns.length;
            if (@noAccessToRecords.ToString().ToLower() === true)
                msg = "No Businesses Exist.";
            $(e.sender.wrapper)
                .find('tbody')
                .append('<tr class="kendo-data-row"><td colspan="' + colCount + '"><div class="alert alert-danger">' + msg + '</div></td></tr>');
            }
        }

    </script>
}

下面是完整的堆栈跟踪

我目前已尝试以下操作: - 删除%TEMP% - 删除 C:\Windows\Temp - 干净的构建 - 删除 IIS 站点并重做 - 删除项目解决方案并从源代码管理中获取新副本

我以前从未见过这样的事情，所以现在我有点迷失。任何帮助或建议将不胜感激。

根据this ，问题出在浏览器链接上。我在使用 Visual Studio 2019 的 ASPNET MVC 5 项目中遇到了同样的问题。关闭浏览器链接后，一切正常。
