C# 无法将剑道网格数据导出到Excel电子表格

我正在从剑道网格导出数据。控制器中的代码在foreach循环中出错而中断

错误消息

  -InvalidCastException-


{"Unable to cast object of type '<>f__AnonymousType2`6[System.DateTime,System.String,System.Int32,System.String,System.String,System.String]' to type 'ZoomAudits.DAL.TypedViewClasses.ReportPhoneSupportResultRow'."}

找到解决办法了。在文件导出操作中使用此代码

ReportPhoneSupportResultTypedView results = new ReportPhoneSupportResultTypedView();
    string[] userIds = model.UserId.Split(',');
    foreach (string userId in userIds)
    {
        int iUserId = 0;
        if (Int32.TryParse(userId, out iUserId))
        {

            RetrievalProcedures.FetchReportPhoneSupportResultTypedView(results, model.FromDate, model.ToDate, iUserId);
        }
    }


    //Get the data representing the current grid state - page, sort and filter
    IEnumerable ExcelResults = ((IEnumerable)results).ToDataSourceResult(request).Data;

请将错误添加到您的问题中，我将其放在顶部。感谢的想法？我需要发布更多信息吗？看起来类型转换是结果集中的问题。您是否调试了代码并检查了excelresults对象的内容？所有数据都在那里？

ReportPhoneSupportResultTypedView results = new ReportPhoneSupportResultTypedView();
    string[] userIds = model.UserId.Split(',');
    foreach (string userId in userIds)
    {
        int iUserId = 0;
        if (Int32.TryParse(userId, out iUserId))
        {

            RetrievalProcedures.FetchReportPhoneSupportResultTypedView(results, model.FromDate, model.ToDate, iUserId);
        }
    }


    //Get the data representing the current grid state - page, sort and filter
    IEnumerable ExcelResults = ((IEnumerable)results).ToDataSourceResult(request).Data;
