嗯..
尽量不要将它声明为实例..抱歉，我之前没有指出
...
只需直接调用System.Drawing.Grapichics.DrawString
或导入System.Drawing.Graphics并调用DrawString。

Um..
Try to not declare it as an instance... sorry I didn''t point that out
earlier...
Just directly call System.Drawing.Grapichics.DrawString
or import System.Drawing.Graphics and just call DrawString.

另一个错误我害怕（有两个解决方案）：
对非共享成员的引用需要对象引用。

Another error I''m afraid (with both solutions):
"Reference to a non-shared member requires an object reference."

只需直接调用System即可。 Drawing.Grapichics.DrawString
或导入System.Drawing.Graphics并调用DrawString。
