我的不便表示歉意

我找到了解決方案如何插入圖像數據庫，但我不知道如何在formview中做到這一點？請幫幫我嗎？謝謝

您必須使用formview ItemInserting事件。

它應該是這個樣子......

protected void FormView1_ItemInserting(object sender, FormViewInsertEventArgs e) 
{ 
    if (fupImage.HasFile) 
    { 
      byte[] myByte = new byte[fupImage.PostedFile.ContentLength]; 
      Stream imgStream = fupImage.PostedFile.InputStream; 
      imgStream.Read(myByte, 0, fupImage.PostedFile.ContentLength); 
      e.Values["personal_image"] = myByte;   
    } 
}

其次改變從String to Object

參數類型此<asp:Parameter Name="personal_image" Type="String" />

應該<asp:Parameter Name="personal_image" Type="Object" />
