我使用下面的代碼來下載文件,但我面對Response.End
總是導致Exception
。這是我的應用程序行爲的成本?如果是的話,如何才能獲得另一種下載文件的方式。我試圖用Thread.ResetAbort()
來處理異常,但這樣的結果不需要額外的數據將被添加到文件使用Response.End()的代價()
try
{
DownloadFiles();
Response.End();
}
catch (ThreadAbortException)
{
// Thread.ResetAbort();
}
catch (GSException ex)
{
Response.ClearHeaders();
hdnResult.Value = ex.Message;
// ClientScript.RegisterStartupScript(this.Page.GetType(), "checkDownloadError", "window.parent.checkDownloadError('" + ex.Message + "');", true);
}
catch (Exception)
{
Response.ClearHeaders();
hdnResult.Value = "Oops! Something unexpected happened. Please try again later";
//ClientScript.RegisterStartupScript(this.Page.GetType(), "checkDownloadError", "window.parent.checkDownloadError('Oops! Something unexpected happened. Please try again later');", true);
}
你有什麼異常? –
