c# mouse buttons

Question

how do I detect left mouse down for .NET 6.0

Answer 1

A way is with IMessageFilter, like :

    public const int WM_LBUTTONDOWN = 0x0201;  
    public const int WM_LBUTTONUP = 0x0202;  

    public Form1()  
    {  
        InitializeComponent();  
        CMessageFilter mf = new CMessageFilter();  
        Application.AddMessageFilter(mf);  
    }  
      
    public class CMessageFilter : IMessageFilter  
    {  
        public bool PreFilterMessage(ref Message m)  
        {                 
            if (m.Msg == WM_LBUTTONDOWN)  
                Console.Beep(1000, 10);  
            return false;  
        }  
    }

if you are working with windows application,
create mouseDown/mouseUp/mouseClick or Click event for control you wanted to use on
,,then check if(e.Button==MouseButton.Left)
