使用Aspose.Words的Document.Save(HttpResponse response, string fileName, ContentDisposition contentDisposition, Aspose.Words.Saving.SaveOption saveOption)方法，将Document直接写入response时，需要加Response.End();
Document doc = new Document(postedFile.InputStream); doc.Save(Response, dstFileName, ContentDisposition.Inline, SaveOptions.CreateSaveOptions(dstFormat)); // Required. Otherwise DOCX cannot be opened on the client (probably not all data sent // or some extra data sent in the response). Response.End();
请注意注释部分！！
Aspose.Words 直接写response导出docx文档显示文件已损坏需要修复的解决办法
