如何通过字符串或int获取枚举值 [英] How to get enum value by string or int
本文介绍了如何通过字符串或int获取枚举值的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
public enum TestEnum
{
Value1 =
Value2 = 2,
Value3 = 3
}
在一些字符串变量中,我有如下值value1:
string str =Value1
或在一些int变量中我有值2像
int a = 2;
如何获取枚举的实例?我想要一个通用的方法,我可以提供枚举和我的输入字符串或int值来获取枚举实例。
解决方案
否,你不想要一个通用的方法。这很容易:
MyEnum枚举=(MyEnum)myInt;
MyEnum枚举=(MyEnum)Enum.Parse(typeof(TestEnum),myString);
我认为这也会更快。
How can I get the enum value if I have the enum string or enum int value. eg: If i have an enum as follows:
public enum TestEnum
{
Value1 = 1,
Value2 = 2,
Value3 = 3
}
and in some string variable I have the value "value1" as follows:
string str = "Value1"
or in some int variable I have the value 2 like
int a = 2;
how can I get the instance of enum ? I want a generic method where I can provide the enum and my input string or int value to get the enum instance.
解决方案
No, you don't want a generic method. This is much easier:
MyEnum enum = (MyEnum)myInt;
MyEnum enum = (MyEnum)Enum.Parse(typeof(TestEnum), myString);
I think it will also be faster.
