How to get the int for enum value in Enumeration

 

This question already has an answer here:

  • Get int value from enum in C# 24 answers

    • To answer your question "how can I get the integer for string value":

    To convert from a string into an enum, and then convert the resulting enum to an int, you can do this: 

    public enum Animals
{
    dog = 0,
    cat = 1,
    rat = 2
}

...

Animals answer;

if (Enum.TryParse("CAT", true, out answer))
{
    int value = (int) answer;
    Console.WriteLine(value);
}

    By the way, normal enum naming convention dictates that you should not pluralize your enum name unless it represents flag values (powers of two) where multiple bits can be set - so you should call it Animal , not Animals .

    Just cast your enum value to integer: 

    Animals animal = Animals.dog;
int value = (int)animal; // 0

    EDIT: if it turns out that you have name of enum value, then parse enum value and cast it to integer: 

    int value = (int)Enum.Parse(typeof(Animals), "dog");

    您可以将其转换为Int或使用Enum.GetValues方法遍历所有值，该方法将检索指定枚举中常量值的数组。
