什么是C＃中的相当于我的函数代码

Question

我想写下VB.net代码到C＃。什么是在C＃最好等效代码：

Private Sub AllControlDesign2(ByRef TB As Control) 
    If TB.GetType Is GetType(StatusStrip) Then 
     CType(TB, TextBox).ReadOnly = True 
     TB.BackColor = stFromBackColour 
     TB.ForeColor = Color.Gray 
    End If 
End Sub 

Answer 1

这是equivellant，从DeveloperFusion.com

private void AllControlDesign2(ref Control TB) 
{ 
    if (object.ReferenceEquals(TB.GetType, typeof(StatusStrip))) { 
     ((TextBox)TB).ReadOnly = true; 
     TB.BackColor = stFromBackColour; 
     TB.ForeColor = Color.Gray; 
    } 
} 

Answer 2

private void AllControlDesign2(ref Control TB) 
{ 
    if (object.ReferenceEquals(TB.GetType, typeof(StatusStrip))) { 
     ((TextBox)TB).ReadOnly = true; 
     TB.BackColor = stFromBackColour; 
     TB.ForeColor = Color.Gray; 
    } 
} 

使用this转换复制。

我会怎么做：

private void AllControlDesign2(Control tb) { 
    var textBox = tb as TextBox; 
    if (textBox != null) { 
     textBox.ReadOnly = true; 
     textBox.BackColor = stFromBackColour; 
     textBox.ForeColor = Color.Gray; 
    } 
}
