下载后，在asp.net中下载.docx文件已损坏。 [英] Downloading .docx file in asp.net is being corrupted after download.

问题描述

大家好，



我在asp.net上传了一个docx类型的文件，iam尝试使用以下代码下载它：

 如果 e.CommandName =  下载 然后 
  Dim  fst 作为 新 FileStream（Server.MapPath（e.CommandArgument），FileMode.Open）
  Dim  fl 作为 字符串 = e .CommandArgument 
  Dim  file  As   String （）= e.CommandArgument.ToString.Split（ 。）
 < span class =code-keyword> Dim  extension < span class =code-keyword> As   String  = file（file.Length  -   1 ）
  Dim  bytBytes（fst.Length） As  字节 
 ' 逐字节读取文件 
 fst .Read（bytBytes， 0 ，fst.Length）
 fst.Close（）
 Response.AddHeader（  Content-disposition， 附件; filename =& fl）
 
 如果 extension =   docx 然后 
 Response.ContentType =    application / vnd.ms-word.document 
  ElseIf  extension =   pdf 然后 
 Response.ContentType =   Application / pdf 
  ElseIf  extension =   xls 然后 
 Response.ContentType =   application / vnd.ms-excel 
  ElseIf  extension =   xlsx 然后 
 Response.ContentType =   application / vnd.ms- excel 
  ElseIf  extension =   doc 然后 
 Response.ContentType =   application / ms-word 
 结束 如果 
 
 
 ' 将所有字节写入新创建的文件 
 Response.BinaryWrite（bytBytes）
响应。结束（）
 结束 如果 
 

除了docx之外的所有其他文件都是下载并打开，但docx文件已下载并损坏。所以如何修复它？



谢谢。

解决方案

更改响应。内容类型。

内容类型：application / vnd.openxmlformats-officedocument.wordprocessingml.document 

为什么使用Response.BinaryWrite（）？



检查这个...... < br $> b $ b

这对我有用。试试!!



string filePath = Server.MapPath（File / Test.docx）; //使用（FileStream fileStream = File.OpenRead（filePath））指定.docx文件的位置



{

MemoryStream memStream = new MemoryStream（）;

memStream.SetLength（fileStream.Length）;

fileStream.Read（memStream.GetBuffer（），0，（int）fileStream.Length）;



Response.Clear（）;

Response.ContentType =application / vnd.openxmlformats-officedocument.wordprocessingml.document;

Response.AddHeader（Content-Disposition，attachment; filename = myfile.docx）;

Response.BinaryWrite（memStream.ToArray（））;

Response.Flush（）;

Response.Close（）;

Response.End（）;

}

Hi all ,

I uploaded a file of type docx in asp.net and iam trying to download it using the following code :

If e.CommandName = "Download" Then
           Dim fst As New FileStream(Server.MapPath(e.CommandArgument), FileMode.Open)
           Dim fl As String = e.CommandArgument
           Dim file As String() = e.CommandArgument.ToString.Split(".")
           Dim extension As String = file(file.Length - 1)
           Dim bytBytes(fst.Length) As Byte
           'read file byte by byte
           fst.Read(bytBytes, 0, fst.Length)
           fst.Close()
           Response.AddHeader("Content-disposition", "attachment; filename=" & fl)

           If extension = "docx" Then
               Response.ContentType = "application/vnd.ms-word.document"
           ElseIf extension = "pdf" Then
               Response.ContentType = "Application/pdf"
           ElseIf extension = "xls" Then
               Response.ContentType = "application/vnd.ms-excel"
           ElseIf extension = "xlsx" Then
               Response.ContentType = "application/vnd.ms-excel"
           ElseIf extension = "doc" Then
               Response.ContentType = "application/ms-word"
           End If


           'write all the byte to newly created file
           Response.BinaryWrite(bytBytes)
           Response.End()
       End If

All the other files except the docx are being downloaded and opened,but the docx file is downloaded and corrupted.So how to fix it ?

Thanks .

解决方案

change the response.Content type.

Content-type: application/vnd.openxmlformats-officedocument.wordprocessingml.document 

Why are you using Response.BinaryWrite() ?

Check this.....

This worked for me. Try out!!

string filePath = Server.MapPath("File/Test.docx"); // Specify the location of the .docx file
using (FileStream fileStream = File.OpenRead(filePath))
{
MemoryStream memStream = new MemoryStream();
memStream.SetLength(fileStream.Length);
fileStream.Read(memStream.GetBuffer(), 0, (int)fileStream.Length);

Response.Clear();
Response.ContentType = "application/vnd.openxmlformats-officedocument.wordprocessingml.document";
Response.AddHeader("Content-Disposition", "attachment; filename=myfile.docx");
Response.BinaryWrite(memStream.ToArray());
Response.Flush();
Response.Close();
Response.End();
}
