winform和vb中锁定窗体和控件

在vb中和wifnorm中锁定窗体需要调用api，下面分别说下是如何调用的。

vb:

Private Declare Function EnableWindow Lib "user32" (ByVal hwnd As Long,ByVal fEnable As Long) As Long

锁定： EnableWindow Me.hwnd,0

解锁：EnableWindow Me.hwnd,1

winform：

[DllImport("user32",CharSet = CharSet.Auto)]
public static extern int EnableWindow(IntPtr hwnd,bool bEnable );

锁定：EnableWindow(this.Handle,false);

解锁：EnableWindow(this.Handle,true);

锁定控件和窗体一样的，控件.Handle
