public static Object ToObject(Type enumType,int value) 比如:Colors color = (Colors)Enum.ToObject(typeof(Colors), 2),那么color即为Colors.Blue 推断某个整型是否定义在枚举中的方法:Enum.IsDefined public static bool IsDefined(Type enumType,Object value) 比如:Enum.IsDefined(typeof(Colors), n)) ...
可以按照以下方式实现转换函数: functionstringToEnumValue<T>(value:string,enumType:T):T[keyofT]|undefined{constenumValues=Object.values(enumType);for(constenumValueofenumValues){if(typeofenumValue==="string"&&enumValue.toLowerCase()===value.toLowerCase()){returnenumValue;}}returnundefined;} 1....
updateSize(Sizes.large); Interesting thing is that you can use enum as Type. This is what compile to Javscript: But if you add 'const' to enum: const enum Sizes { Small= "small", Medium= "medium", Large= "large" } It compiles to such smaller amount code, with only necessary info...

consta:string='1'; 此时a的值就必须是个字符串。而有时候我们希望某个变量的值,是按照我们预设好的值其一,这里就可以用联合类型结合字面量类型来达到效果,比如: typeNameType='echo'|'听风是风'|'时间跳跃';constuser:NameType='echo'; 此时user就只能是echo这三个值其一,这在我们日常开发中,当为组件预设...
GitHub - anc95/golang-enum-to-ts: Transform Golang `enum` type to Typescript enumgithub.com/anc95/golang-enum-to-ts 看到这个标题,你也许会觉得很奇怪,我为什么要把Golang的enum转换成Typescript呢?它的实际价值是什么?下面我会介绍一下最初要做这个的动机和想法 ...
Type 'string' is not assignable to type 'Enum'.(2322) 我在某种程度上理解了背后的逻辑,因为在[]中,我可以把不存在于枚举上的键放进去,但是键本身就是枚举本身,所以它应该有足够的信心返回枚举,而不仅仅是字符串。因为Object.values(Enum)同时返回键和值,所以获取键仍然应该是enum。 有什么解决办法吗?发...

枚举成员用一个常量枚举表达式进行初始化。常量枚举表达式是TypeScript表达式的一个子集,可以在编译时对其进行全面评估。表达式是一个常量枚举表达式,如果它是: 代码语言:txt 复制 - a literal enum expression (basically a string literal or a numeric literal) - a reference to previously defined constant enum me...
