首先,所有这些都发生在本地内部网上,在任何时候都不需要连接到互联网。
我有一个运行查询的数据库,之后用户按下“下载电子表格”按钮,创建/发送电子表格。电子表格的创建工作正常,但经过多次尝试后我无法下载该文件。这是我尝试过的:
在大多数情况下,结果是创建了excel文件,但没有发生重定向/下载。在Response.Redirect()的情况下,如果它是一个网站,它工作得很好,但如果它是一个重定向到file:///,那么它会抛出一个线程异常,但没有更多细节。
我怀疑它与ASP.NET文档的生命周期有关,但我担心我对ASP.NET的经验不足以确定无疑。

ClientScript.RegisterStartupScript(GetType(), "hwa", "window.open('" + System.Configuration.ConfigurationManager.AppSettings["WebSite"].ToString() + "Document/SummaryReport/" + FileName + "','_blank');", true);
是按钮点击代码是Excel文件下载吗?所以现在可以使用c#代码轻松下载excel文件。
