ASP.NET存储区上载的文件sql server表

关于如何将文件直接上传到数据库,有很好的教程 4GuysFromRolla

下面是我如何使用Linq To Sql实现这一点的:

FilesDataContext db = new FilesDataContext();

protected void btnUpload_Click(object sender, EventArgs e)
{
    for (int i = 0; i < Request.Files.Count; i++)
    {
        StoreFile(Request.Files[i]);
    }

    db.SubmitChanges();
}

private void StoreFile(HttpPostedFile file)
{
    byte[] data = new byte[file.ContentLength];
    file.InputStream.Read(data, 0, file.ContentLength);

    File f = new File();
    f.Data = data;
    f.Filename = file.FileName;
    db.Files.InsertOnSubmit(f);
}

Public Shared Sub SaveUploadedFile(File As HttpPostedFile)
  Dim oFile As Db.File

  oFile = New Db.File
  oFile.Data = File.ToBytes
End Sub

<Extension()>
Public Function ToBytes(File As HttpPostedFile) As Byte()
  ToBytes = New Byte(File.ContentLength - 1) {}

  Using oStream As Stream = File.InputStream
    oStream.Read(ToBytes, 0, File.ContentLength)
  End Using
End Function

嗯
