Question

C#如何控制鼠标移动范围?

Answer 1

//锁定鼠标活动范围:
void LockCursor()
{
this.Cursor=new Cursor(Cursor.Current.Handle);
Cursor.Position=new Point(Cursor.Position.X,Cursor.Position.Y);
Cursor.Clip=new Rectangle(this.Location,this.size);//这里是窗体的大小.即鼠标只能在窗体范围内活动.如果要改成控件,只改动this.Location,this.size.
}
如果是,textBox txtbox:则:
void LockCursor()
{
this.Cursor=new Cursor(Cursor.Current.Handle);
Cursor.Position=new Point(Cursor.Position.X,Cursor.Position.Y);
Cursor.Clip=new Rectangle(txtbox.Location,txtbox.size);
}
希望对你有用!

this.Cursor=new Cursor(Cursor.Current.Handle)；
Cursor.Position=new Point(Cursor.Position.X,Cursor.Position.Y)；
Cursor.Clip=new Rectangle(this.Location,this.size)；//这里是窗体的大小.即鼠标只能在窗体范围内活动.如果要改成控件，只改动this.Location,this.size.
