您必须使用 formview ItemInserting 事件。

它应该看起来像...

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;           
    }
}

其次将参数类型从 String 更改为 Object

这个

应为

You have to use the formview ItemInserting event.

It should look something like...

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;           
    }
}

Secondly change the parameter type from String to Object

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

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