上面的代码中,我们首先定义了一个colorString变量,并将其赋值为"Red"。然后,我们使用Color[colorString]将colorString转换为对应的枚举值。 状态图 最后,让我们使用mermaid语法来展示一个状态图,以更清晰地描述整个流程: 定义枚举将枚举值转换为字符串将字符串转换为枚举值 以上就是实现"typescript enum string 转换"...
public static string GetName(Type enumType,Object value) public static string[] GetNames(Type enumType) 比如:Enum.GetName(typeof(Colors),3))与Enum.GetName(typeof(Colors), Colors.Blue))的值都是"Blue" Enum.GetNames(typeof(Colors))将返回枚举字符串数组。 1. 2. 3. 4. 5. 6. 7. 8. ...
限定了某个变量，这个时候你调用函数或者使用变量的时候就必须和接口里面的限定一模一样，...
[TypeScript] String Enums and Inlining Members enum Sizes { Small= "small", Medium= "medium", Large= "large"} letselected: Sizes=Sizes.Samll;functionupdateSize(size: Sizes):void{ selected=size; } updateSize(Sizes.large); Interesting thing is that you can use enum as Type. This is what...
However, instead of string literal, I want to use string enum type instead. So I wrote something like this class Dog {} class Cat {} class Bird {} enum Kind { Dog = 'Dog', Cat = 'Cat', Bird = 'Bird' } interface KindMap { [Kind.Dog]: Dog [Kind.Cat]: Cat [Kind.Bird]: ...
Following code can be used to create an enum in TypeScript: enum e { hello = 1, world = 2 }; And the values can be accessed by: e.hello; e.world; How do I create an enum with string values? enum e { hello = "hello", // error: cannot convert string to e world = "...

A string enum is inferred by looking at the constant value of the initializer of its first member: enum stringsInferred { a = "a", b, // "b" c // "c" } Or it is declared using a string index: enum stringsDeclared { [prop: string] : strin...
