当从浏览器返回一个文件时,需要指定ContentType,以下是Office2007对应的值:

　　"application/vnd.openxmlformats-officedocument.wordprocessingml.template" (for .dotx files)

　　"application/vnd.openxmlformats-officedocument.presentationml.presentation" (for .pptx files)

　　"application/vnd.openxmlformats-officedocument.presentationml.slideshow" (for .ppsx files)

　　"application/vnd.openxmlformats-officedocument.presentationml.template" (for .potx files)

　　"application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" (for .xlsx files)

　　"application/vnd.openxmlformats-officedocument.spreadsheetml.template" (for .xltx files)

　　相对于Office2003是这样的

　　Response.ContentType = "application/vnd.ms-excel"
