MsgBox為什么要端击两次确认_ASP.NET

MsgBox為什么要点击两次确认？

VB.NET code

 MsgBox("確認刪除這條數據嗎", MsgBoxStyle.YesNo)//要点击两次确认  Dim resultCode As Integer = 0        resultCode = MsgBox("asd", MsgBoxStyle.YesNo).GetHashCode        If resultCode = MsgBoxResult.Yes Thenend if

------解决方案--------------------------------------------------------
If MsgBox("asd", MsgBoxStyle.YesNo).GetHashCode == DialogResult.Yes Then
试试，我不是很懂vb，你查一下msdn，只用一行代码或者用DialogResult枚举，就会只点一次。原理大概是因为MsgBoxResult.Yes 又实例化了一次，好像，记不得了

C# code

private void button1_Click(object sender, EventArgs e)        {            if (MessageBox.Show("hegheheh","warning",MessageBoxButtons.YesNo)== DialogResult.Yes)             {                this.label1.Text = "sucess";            }        }
