从C#错误打开Office 2010文档

我正在尝试通过为用户加载office文档

HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name); 
HttpContext.Current.Response.ContentType = MIMETypesDictionary[fileExt];
HttpContext.Current.Response.BinaryWrite(fileArray);

我的MIMETypesDictionary有这个（缩写）

文字错误

The file filename.docx cannot be opened because there are problems with the contents.

如果我单击Yes，它会加载，文档看起来也不错。当然，对于用户来说，这个错误不会出现。我是否为这些文件使用了正确的mime类型？我还尝试了application/vnd.ms-word.document.12、application/vnd.ms-excel.12和application/octet-stream，得到了相同的错误

谢谢

解决了！必须建立响应代码

HttpContext.Current.Response.Clear();
HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name); 
HttpContext.Current.Response.ContentType = MIMETypesDictionary[fileExt];
HttpContext.Current.Response.BinaryWrite(fileArray);
HttpContext.Current.Response.End();
HttpContext.Current.Response.Flush();

我保留了文件类型的八位字节流值，效果非常好

您是否尝试过仅使用“应用程序/八位字节流”作为内容类型。我刚刚为流文件编写了一些东西，仅使用它就足以处理docx文件。

The file filename.docx cannot be opened because there are problems with the contents.

HttpContext.Current.Response.Clear();
HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name); 
HttpContext.Current.Response.ContentType = MIMETypesDictionary[fileExt];
HttpContext.Current.Response.BinaryWrite(fileArray);
HttpContext.Current.Response.End();
HttpContext.Current.Response.Flush();
