所以我正在做的是使用epplus创建一个excel文件并将其保存到response.outputstream
由于某种原因，代码中断给我一个错误。我不知道我做错了什么。

我收到此错误
0x800a139e - Microsoft JScript运行时错误：Sys.WebForms.PageRequestManagerParserErrorException：无法解析从服务器收到的消息。
答案 0 :(得分：1)
你可能从UpdatePanel或Ajax调用中调用它 - 但是你用它来清除响应头而不是json ajax等待返回，你发送一些不同的东西（这里是一个xlsx文件） - 而你得到那条消息，无法解析那个excel。
ajax或UpdatePanel无法理解您尝试发送与此文件不同的内容。你必须做的是创建发送此文件的ether处理程序，并将其放在超链接中，以便删除UpdatePanel。
