Vb.net 布尔属性将不会设置为True

我有一个非常基本的表单，上面有1个标签、文本框和按钮

单击“确定”按钮时，我需要检查文本框（

txtserver

）是否为空。如果是这样，我将属性

ServersError

设置为

True

然而，我用于此的

IIF

语句不起作用。然后我直接将

ServersError

设置为

True

（正如您在代码中看到的），但由于某种原因，当我直接输出结果时，它仍然返回

False

我是疯了，还是这里发生了什么奇怪的事？！谢谢

Public Class formServers

    Private m_ServersError As Boolean = False   ' Whether or not there is an error with the specified servers

    Public Property ServersError() As Boolean
        Get
            ServersError = m_ServersError
        End Get
        Private Set(value As Boolean)
            m_ServersError = ServersError
        End Set
    End Property

    Private Sub btnOK_Click(sender As Object, e As EventArgs) Handles btnOK.Click
        'Me.ServersError = IIf(Me.txtServers.Text.Length = 0, True, False)
        Me.ServersError = True
        MsgBox(Me.ServersError)
        Me.Hide()
    End Sub

End Class

我不是VB的人，但不应该是这样吗

Public Class formServers

    Private m_ServersError As Boolean = False   ' Whether or not there is an error with the specified servers

    Public Property ServersError() As Boolean
        Get
            ServersError = m_ServersError
        End Get
        Private Set(value As Boolean)
            m_ServersError = value ' <--------------- changed here
        End Set
    End Property

    Private Sub btnOK_Click(sender As Object, e As EventArgs) Handles btnOK.Click
        'Me.ServersError = IIf(Me.txtServers.Text.Length = 0, True, False)
        Me.ServersError = True
        MsgBox(Me.ServersError)
        Me.Hide()
    End Sub

End Class

公共类formServers
Private m_ServersError As Boolean=False'无论指定的服务器是否存在错误
公共属性ServersError（）为布尔值
得到
ServersError=m_ServersError
结束
私有集（值为布尔值）
m_ServersError=值“正确”。谢谢，我看不见！
