从typescript中的字符串获取枚举

enum Color {
  Red = "red",
  Green = "green",
  Blue = "blue"
}

function getColorFromString(colorString: string): Color | undefined {
  return colorString as Color;
}

const colorString = "red";
const color = getColorFromString(colorString);
console.log(color); // 输出：Color.Red
