问题描述
||
使用此方法导出excel文件:
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.AddHeader(\"content-disposition\",string.Format(\"attachment; filename={0}\",\"Single_Raw.xls\"));
HttpContext.Current.Response.ContentType = \"application/vnd.ms-excel\";
using (StringWriter sw = new StringWriter())
{
using (HtmlTextWriter htw = new HtmlTextWriter(sw))
{
// some code
HttpContext.Current.Response.Write(sw.ToString());
HttpContext.Current.Response.End();
}
}
但是这种方法有很大的局限性,每次我打开Excel文件时Excel都会显示此警告:
The file you are trying to open < > is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?
向我建议的第二种方法是使用Interop,但也有一些限制:

其中之一是,所有客户端计算机都应具有相同的Excel版本。
现在,我正在拼命寻找其他方法,即使这意味着要使用第三方插件。只要它是免费的,并且可以在公司网站中使用。
