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"的全部步骤和代码示例。希望这篇文章对你有...
function stringToEnum(enumType: any, enumString: string): any { return enumType[enumString]; } const colorString = "Green"; const colorEnum = stringToEnum(Color, colorString); console.log(colorEnum); // 输出: Color.Green 处理未定义的情况:如果传入的字符串值在枚举中不存在,上述代码将返回...
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. ...

Generic TypeScript Visitor for String Enums and String Literal Union Types - UselessPickles/ts-string-visitor
String enums TypeScript has had string literal types for quite some time now, and enums since its release. Having had some time to see how these features were being used, we revisited enums for TypeScript 2.4 to see how they could work together. This release of TypeScript now allows enu...
