This should do it for you:
这应该为你做：
'just a solid brush:
Using br = New SolidBrush(Colors.Black)
e.Graphics.FillRectangle(br, New Rectangle(50, 50, 10, 10))
End Using
'A red -> orange gradient, at 45 degrees:
Using br = New LinearGradientBrush(new Rectangle(50, 50, 10, 10), Color.Red, Color.Orange, 25)
e.Graphics.FillRectangle(br, New Rectangle(50, 50, 10, 10))
End Using

A "Brush" is a style of fill drawing, incorporating both a Color and a Pattern. A Pen is similar to a Brush but defines a style of line drawing. To go from a Color to a Brush, you need to create a new Brush and give it the Color. The Brush class itself is abstract; its child classes specify various basic, customizable patterns of drawing. Pens are similar, but as lines are drawn as if they were filled rectangles, a Brush may be necessary to customize the "fill" of the line. The Pen object then has additional properties governing style that are specific to drawing a line. Take a look on MSDN: http://msdn.microsoft.com/en-us/library/d78x2d7s%28v=VS.71%29.aspx
“画笔”是一种填充绘图风格，包含颜色和图案。Pen 类似于 Brush，但定义了一种线条绘制风格。要将颜色转换为画笔，您需要创建一个新画笔并为其指定颜色。Brush 类本身是抽象的；它的子类指定了各种基本的、可定制的绘图模式。钢笔是类似的，但当线条被绘制成填充矩形时，可能需要画笔来自定义线条的“填充”。然后 Pen 对象具有控制特定于绘制线条的样式的附加属性。看看 MSDN：http: //msdn.microsoft.com/en-us/library/d78x2d7s%28v=VS.71%29.aspx

They are entirely different things.
它们是完全不同的东西。
Here is an article entitled 'Pens, Brushes and Colors' http://msdn.microsoft.com/en-us/library/aa983677(v=vs.71).aspx
这是一篇题为“钢笔、画笔和颜色”的文章 http://msdn.microsoft.com/en-us/library/aa983677(v=vs.71).aspx
Pens
A pen is used to draw lines, curves, and to outline shapesBrushes
Brushes are objects that are used with a Graphics object to create solid shapes and to render text.
钢笔
钢笔用于绘制线条、曲线和勾勒形状画笔
画笔是与 Graphics 对象一起使用以创建实体形状和呈现文本的对象。
Both Pens and Brushes have a 'Color' that they are using...but you can't turn a Color into a brush. It's like a car. You can't turn 'Red' into a car, but a car can be red.
钢笔和画笔都有他们正在使用的“颜色”……但是你不能把颜色变成画笔。这就像一辆汽车。你不能把“红色”变成汽车，但汽车可以是红色的。
