How to avoid repetitive code in CodeLab

How to put repetitive code in a method or subroutine?

switch (AmountX)
{
case 0:
{
//some code here, eg.
gPen.DashStyle = DashStyle.Solid;
gPen.Width = 5;

//here is the repetitive code e.g
g.DrawLine (gPen, a, b, c, d);
...
}
break;

case 1:
{
//some code here, eg.
gPen.DashStyle = DashStyle.Dash;
gPen.Width = 6;

//here is the repetitive code e.g
g.DrawLine (gPen, a, b, c, d);
...
}

break;

Google suggests this.

try
	{
	switch (AmountX)
		{
		case 0:
			{
			//some code here, eg.
			gPen.DashStyle = DashStyle.Solid;
			gPen.Width = 5;
			} break;

		case 1:
			{
			//some code here, eg.
			gPen.DashStyle = DashStyle.Dash;
			gPen.Width = 6;
			} break;
		} 
	}
finally
	{
	//here is the repetitive code e.g
	g.DrawLine (gPen, a, b, c, d);
	}

Does this look sane?

Thank you Zagna, but I'm looking for something else.
Something like call Subroutine (name) – Return like in assembler.
Google suggestion does not work.

In that particular case, you could have an array of DashStyes and an array of ints (or an array of a struct containing both). The arrays would be initialized to the proper values, then indexed by AmountX to get the gPen.DashStyle and gPen.Width.

gPen.DashStyle = penDashStyle[AmountX];
gPen.Width = penWidth[AmountX];
g.DrawLine (gPen, a, b, c, d);

It could, of course, be put in a separate method.
