推荐答案
我想这个问题是有没有完全得到写进响应字节。
请尝试以下方法，并希望它应该工作。
I guess the problem is the with the bytes not completely getting written into the response. Try the following and hopefully it should work.
HttpContext context = HttpContext.Current;
context.Response.Clear();
context.Response.ContentType = "application/vnd.ms-xpsdocument";
context.Response.AppendHeader("Content-Disposition", "attachment; filename=document.xps");
context.Response.End();
