c# - How to get a right click mouse event? Changing EventArgs to MouseEventArgs causes an error in Form1Designer?

Question

I have a method to detect the left click event that visual studio made by double clicking on the form.

private void pictureBox1_Click(object sender, EventArgs e)
{
    MessageBox.Show("Left click");
}

I want to have a right-click event by right-clicking on the same object.

I read online that you can use this switch:

private void pictureBox1_Click(object sender, EventArgs e)
{
    if (e.Button == System.Windows.Forms.MouseButtons.Right){MessageBox.Show("Right click");}
    if (e.Button == System.Windows.Forms.MouseButtons.Left){MessageBox.Show("Left click");}
}

The trouble is that when I do e.Button it has has yields an error error:

System.EventArgs does not contain a definition for Button...

So I fix this by changing the EventArgs.e to MouseEventArgs.e

But then there is a new error in Form1Designer where the event line is:

this.pictureBox1.Click += new System.EventHandler(this.pictureBox1_Click);

The error says:

No overload for pictureBox1_Click matches delegate System.EventHandler

How do I fix this? Thanks for reading

Answer 1

You should introduce a cast inside the click event handler

MouseEventArgs me = (MouseEventArgs) e;
