枚举和数字、字符串之间的相互转化

https://blog.csdn.net/ngany/article/details/108393970

既上一篇博客中写的吧RadioButton选择的星期几传送到字符串today，方法是switch枚举类型，case给字符串today赋值。但是如果可以把枚举类型直接转化成字符串代码会简洁很多。

public WeekEnum week { get { return _week; } set { _week = value; this.today = this.EnumConvertToString(_week); this.RaisePropertyChanged("week"); } }

1.枚举类型转换为字符串

private string EnumConvertToString(WeekEnum day) { //方法一 //return color.ToString(); //方法二 return Enum.GetName(day.GetType(), day); }

2.枚举类型转换为数字

private int EnumConvertToInt(WeekEnum day) { return (int)day; }

3.字符串转换为枚举类型

private WeekEnum StringConvertToEnum(string str) { WeekEnum day = WeekEnum.Monday; try { day = (WeekEnum)Enum.Parse(typeof(WeekEnum), str); } catch (Exception ex) { MessageBox.Show(ex.Message); return day; } return day; }

4.数字转换为枚举类型

private WeekEnum IntConvertToEnum(int i) { if (Enum.IsDefined(typeof(WeekEnum), i)) { return (WeekEnum)Enum.ToObject(typeof(WeekEnum), i); } return WeekEnum.Monday; // return (enumColor)i; }
