如何改变字体风格?

改变字体风格要比改变它的大小要容易一点,因为在字体的构造函数中可以传一个字体风格作为参数.举个例子:一个加粗的标签字体:

![None.gif][] Label label  =   new  Label();  
![None.gif][]. . .  
![None.gif][]label.Font  =   new  Font( label.Font, FontStyle.Bold );

如果你想保持初始的风格并且加粗它:

![None.gif][]     label.Font  =   new  Font( label.Font, label.Font.Style  |  FontStyle.Bold );  
![None.gif][]

上面的解决方法创建了一个新字体对象,不管需不需要!这儿有一个更方便的方法,加粗字体,仅当需要时才新创建一个字体对象:

![None.gif][] static   public  Font BoldFont( Font font )  
![ExpandedBlockStart.gif][]![ContractedBlock.gif][] ![dot.gif][] \{  
![InBlock.gif][]    if (font != null)  
![ExpandedSubBlockStart.gif][]![ContractedSubBlock.gif][]    ![dot.gif][]\{  
![InBlock.gif][]        FontStyle fontStyle = font.Style;  
![InBlock.gif][]        if ((fontStyle & FontStyle.Bold) == 0)  
![ExpandedSubBlockStart.gif][]![ContractedSubBlock.gif][]        ![dot.gif][]\{  
![InBlock.gif][]            fontStyle |= FontStyle.Bold;  
![InBlock.gif][]            font = new Font( font, fontStyle );  
![ExpandedSubBlockEnd.gif][]        \}  
![ExpandedSubBlockEnd.gif][]    \}  
![InBlock.gif][]    return font;  
![ExpandedBlockEnd.gif][]\}

举个例子,加粗一个标签字体:

![None.gif][] label.Font  =  BoldFont( label.Font );
