一、目的：在開發(fā)過程中綁定的枚舉不想顯示成英文字段怎么辦，這里通過TypeConverter的方式來實現(xiàn)綁定的枚舉從定義的特性中讀取

二、實現(xiàn)

首先定義如下枚舉

    [TypeConverter(typeof(DisplayEnumConverter))]public enum MyEnum{[Display(Name = "無")]None,[Display(Name = "第一個")]First,[Display(Name = "第二個")]Second,[Display(Name = "第三個")]Third}

其中DisplayEnumConverter是一個TypeConverter，繼承自EnumConverter

   public class DisplayEnumConverter : EnumConverter{public DisplayEnumConverter(Type type): base(type){}public override object ConvertTo(ITypeDescriptorContext context, CultureInfo culture, object value, Type destinationType){if (destinationType == typeof(string)){if (value != null){FieldInfo field = value.GetType().GetField(value.ToString());if (field != null){DisplayAttribute[] array = (DisplayAttribute[])field.GetCustomAttributes(typeof(DisplayAttribute), inherit: false);if (array.Length == 0 || string.IsNullOrEmpty(array[0].Name)){return value.ToString();}return array[0].Name;}}return string.Empty;}return base.ConvertTo(context, culture, value, destinationType);}public override object ConvertFrom(ITypeDescriptorContext context, CultureInfo culture, object value){return base.ConvertFrom(context, culture, value);}}

三、環(huán)境

VS2022

四、示例?

頁面上定義一個ComboxBox并綁定該枚舉

<ComboBox ItemsSource="{h:GetEnumSource EnumType={x:Type local:MyEnum}}"/>

對GetEnumSource具體實現(xiàn)參考文章：示例:WPF中綁定枚舉到ComboBox的方式-CSDN博客?

?

顯示效果如下?
