我正在使用实体框架。我以这种方式将表格导出到excel：

DetailsSet TheDetails = db.DetailsSet.SingleOrDefault(x => x.Id == id);
            string filename = Guid.NewGuid() + ".xls";
            StringWriter tw = new System.IO.StringWriter();
            HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(tw);
            DataGrid dgGrid = new DataGrid();
            // var List = db.GetRegList(TheDetails.CorrectAnswer);
            List<RegistrationSet> RegList = TheDetails.RegistrationSet.Where(x => x.Answer == TheDetails.CorrectAnswer).ToList();
            dgGrid.DataSource = RegList;
            dgGrid.DataBind();
            dgGrid.RenderControl(hw);
            Response.ContentType = "application/vnd.ms-excel";
            Response.AppendHeader("Content-Disposition", "attachment; filename=" + filename + "");

            Response.Write(tw.ToString());
            Response.End();

问题是在 excel 中，db 中的所有希伯来文文本都显示为 gibresh。当我.Where(x => x.Answer == TheDetails.CorrectAnswer)从网格中删除时，excel 正常 - 意味着希伯来语中的所有文本都正常。

像这样没关系：

List<RegistrationSet> RegList = TheDetails.RegistrationSet.ToList();

但像这样，不行：

List<RegistrationSet> RegList = TheDetails.RegistrationSet.Where(x => x.Answer == TheDetails.CorrectAnswer).ToList();

OK 函数的完整示例：

DetailsSet TheDetails = db.DetailsSet.SingleOrDefault(x => x.Id == id);
            string filename = Guid.NewGuid() + ".xls";
            StringWriter tw = new System.IO.StringWriter();
            HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(tw);
            DataGrid dgGrid = new DataGrid();
            // var List = db.GetRegList(TheDetails.CorrectAnswer);
            List<RegistrationSet> RegList = TheDetails.RegistrationSet.ToList();
            dgGrid.DataSource = RegList;
            dgGrid.DataBind();
            dgGrid.RenderControl(hw);
            Response.ContentType = "application/vnd.ms-excel";
            Response.AppendHeader("Content-Disposition", "attachment; filename=" + filename + "");

            Response.Write(tw.ToString());
            Response.End();
