问题描述
全部问候,
我有这个Enum类型,我想给标准和值一个字符串值,我该怎么办?

条件,
/// < 备注/ >
价值,
}
我想在字符串上传送ItemsChoiceType1而不添加任何内容枚举类型,因为它是由我使用的API提供的
请帮助!
解决方案
您可以添加Description属性
public enum ChartType : short
{
Pie = 1 ,
Donut = < span class =code-digit> 2 ,
Column =3 ,
[描述( 列堆积的 )]
ColumnStacked = 4 ,
Area = 5 ,
[描述( 堆积区域)]
AreaStacked = 6 ,
[描述( Area Spline)]
AreaSpline = 7 ,
Bar = 8 ,
[描述( Bar Stacked)]
BarStacked = 9 ,
行= 10 ,
Spline = 11
}
您可以通过以下h获得描述elper
public static class EnumExt
{
public static string Description(this Enum en)
{
string result = en的ToString();
类型EnumType = en.GetType();
FieldInfo fi = EnumType.GetField(result);
var da = Attribute.GetCustomAttribute(fi,typeof(DescriptionAttribute))as DescriptionAttribute;
return(da!= null?da.Description:result);
}
}
ChartType.BarStacked.Description()
Greeting All ,
I have this Enum type and I want to give a string value to criteria and value , how should I do ?
public enum ItemsChoiceType1 {
/// <remarks/>
Criteria,
/// <remarks/>
Value,
}
I would like to convet ItemsChoiceType1 on string without adding any things to the enum type because it is provided by the API that I use

解决方案
You can add Description attribute
public enum ChartType : short { Pie = 1, Doughnut = 2, Column = 3, [Description("Column Stacked")] ColumnStacked = 4, Area = 5, [Description("Area Stacked")] AreaStacked = 6, [Description("Area Spline")] AreaSpline = 7, Bar = 8, [Description("Bar Stacked")] BarStacked = 9, Line = 10, Spline = 11 }
You can get Description by below helper
public static class EnumExt { public static string Description(this Enum en) { string result = en.ToString(); Type EnumType = en.GetType(); FieldInfo fi = EnumType.GetField(result); var da = Attribute.GetCustomAttribute(fi, typeof(DescriptionAttribute)) as DescriptionAttribute; return (da != null ? da.Description : result); } }
ChartType.BarStacked.Description()
