如何去掉TextBox可输入状态时的光标

c#中不能直接隐藏可编辑控件的光标的功能，真是奇怪！

只能通过WINDOWS API的HideCaret函数来实现

HideCaret函数的申明：


[DllImport("user32", EntryPoint = "HideCaret")]


private static extern bool HideCaret(IntPtr hWnd);

为TextBox添加MouseDown事件：


textbuttons[i].MouseDown += new MouseEventHandler(FrmSend_MouseDown);


void FrmSend_MouseDown(object sender, MouseEventArgs e)




...{


//throw new Exception("The method or operation is not implemented.");


HideCaret(((TextBox)sender).Handle);




}
