GC.drawString介绍

[英]Draws the given string, using the receiver's current font and foreground color. No tab expansion or carriage return processing will be performed. The background of the rectangular area where the string is being drawn will be filled with the receiver's background color.
[中]使用接收者的当前字体和前景色绘制给定字符串。不执行制表符扩展或回车处理。正在绘制字符串的矩形区域的背景将用接收者的背景色填充。

代码示例
