 var dt=JobContext.GetEngagementLetterReport(SPContext.Current.Site, int.Parse(rdlOption.SelectedValue));

                    HttpContext.Current.Response.Write("\n");
                }
                HttpContext.Current.Response.End();
            }
            catch (Exception ex)
            {
                string errorMessage = String.Format("ExportToExcelError: {0}", ex.Message);
                LoggingService.LogError(LoggingCategory.General, ex, errorMessage);
                throw;
            }
        }

【问题讨论】：

您是否尝试使用值为“text/csv; charset=utf-8”的标题“Content-Type”？
那没有帮助，我注意到数据表上的数据是正确的。 screencast.com/t/4tVJKW5jG9p

标签： c# asp.net excel

【解决方案1】：

设置内容类型后尝试添加以下内容。

// This is the missing part from your original code to set the charset and encoding - if this does not work, replace it with appropriate value, eg Response.Charset = "utf-8"; Response.ContentEncoding = Encoding.UTF8;

// You might want to use this content type or experiment with appropriate MIME type Response.ContentType = "text/csv";

TQ。
