我为给您带来的不便而道歉

我找到了如何将图像插入数据库的解决方案，但我不知道如何在formview中执行此操作？请帮我？谢谢

Answer 1

您必须使用formview ItemInserting事件。

应该看起来像......

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;           
    }
}

其次从String to Object

更改参数类型

这<asp:Parameter Name="personal_image" Type="String" />

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

如何在formview中将图像插入数据库？
