asp.net - 使用 vb.net for vs2010 显示 .ppt/.pptx 文件

Question

我使用以下代码来显示 .pdf 文件，但相同的代码不适用于 .ppt/.pptx 文件。需要建议。

If file.Name.Contains(Left(lblMth.Text, 3) & lblYr.Text) Then
    Response.Clear()
    Response.ClearContent()
    Response.ClearHeaders()

    Dim path As String = file.FullName 'strLine & GridView1.Rows(index).Cells(1).Text()
    Dim client As New WebClient()
    Dim buffer As [Byte]() = client.DownloadData(path)

    If buffer IsNot Nothing Then
        Response.ContentType = "application/pdf"
        Response.AddHeader("content-length", buffer.Length.ToString())
        Response.BinaryWrite(buffer)
    End If
End If

您需要为要发送的文件类型设置正确的内容类型:

.ppt

application/vnd.ms-powerpoint

.pptx

application/vnd.openxmlformats-officedocument.presentationml.presentation
