如何将枚举分配给变量 [英] How to assign enum to variable

问题描述

如何从声明的枚举中分配新变量

How to assign new variable from declared enum

public enum FontStyle
{
 Regular = 0;
 Bold =1;
 Italic = 2
}
// dont know what Type to cast it :/
TYPE fontstyle = FontStyle.Bold;

我不确定要强制转换哪种类型，它包含在System.Drawing类中.

I am not sure which TYPE to cast it, It is contained within System.Drawing class.

推荐答案

其类型为 FontStyle ，即枚举是一流的类型.

It's of type FontStyle i.e. Enums are first class types.

public enum FontStyle
{
    Regular = 0;
    Bold =1;
    Italic = 2
}

// No need to cast it
FontStyle fontstyle = FontStyle.Bold;

也许您有这样的代码:

if(1 == 1)
    FontStyle fontstyle = FontStyle.Bold;    

对于您的错误(嵌入式语句不能是声明或标记的语句)，例如，将代码包围在块语句中

for your error (Embedded statement cannot be a declaration or labeled statement) surround your code in a block statement e.g.

if(1 == 1)
{
    FontStyle fontstyle = FontStyle.Bold;    
}
