Tutorial :C#: PointF() Array Initializer



Question:

I need to hard code an array of points in my C# program. The C-style initializer did not work.

PointF[] points = new PointF{      /* what goes here? */  };  

How is it done?


Solution:1

Like this:

PointF[] points = new PointF[]{      new PointF(0,0), new PointF(1,1)  };  

In c# 3.0 you can write it even shorter:

PointF[] points = {      new PointF(0,0), new PointF(1,1)  };  

update Guffa pointed out that I was to short with the var points, it's indeed not possible to "implicitly typed variable with an array initializer".


Solution:2

You need to instantiate each PointF with new.

Something like

Pointf[] points = { new PointF(0,0), new PointF(1,1), etc...

Syntax may not be 100% here... I'm reaching back to when I last had to do it years ago.


Solution:3

PointF[] points = new PointF[]  {      new PointF( 1.0f, 1.0f),      new PointF( 5.0f, 5.0f)  };  


Solution:4

For C# 3:

PointF[] points = {     new PointF(1f, 1f),     new PointF(2f, 2f)  };  

For C# 2 (and 1):

PointF[] points = new PointF[] {     new PointF(1f, 1f),     new PointF(2f, 2f)  };
