跳过为结构提供完整名称空间引用的最佳方法是什么？

Question

I want to declare an array of colors, to be used as 8-bit style sprites.

spriteArray = new System.Drawing.Color[2,2] {
{System.Drawing.Color.Red, System.Drawing.Color.Blue},
 {System.Drawing.Color.Blue, System.Drawing.Color.Red}
};

It's a pain, and looks verbose writing out the namespace path each time - what would the best way to reduce it to something like:

spriteArray = new System.Drawing.Color[2,2]
{{RED, BLUE},
 {BLUE, RED}};

be?

Answer 1

Include a using directive at the top of your code file:

using System.Drawing;

Then it's just:

spriteArray = new Color[2,2]
{
    { Color.Red, Color.Blue },
    { Color.Blue, Color.Red } 
};

Answer 2

declare it on top ?

using System.Drawing;

...
spriteArray = new Color[2,2]
  {{Color.Red, Color.Blue},
 {Color.Blue, Color.Red}};

or if there is a name conflict, if there is another class with Color name, you can:

using SysDraw = System.Drawing;
 ...
spriteArray = new SysDraw.Color[2,2]
  {{SysDraw.Color.Red, SysDraw.Color.Blue},
 {SysDraw.Color.Blue, SysDraw.Color.Red}};

Answer 3

The only way to remove the names completely is to add them as local fields, variables or constants. Since Color is not an enum , you can't use the const approach, but you could do:

using System.Drawing;
//...
private static readonly Color Red = Color.Red, Blue = Color.Blue;
//...
spriteArray = new[,] {
    { Red, Blue },
    { Blue, Red },
};
