一、目的：在开发过程中绑定的枚举不想显示成英文字段怎么办，这里通过TypeConverter的方式来实现绑定的枚举从定义的特性中读取
二、实现
首先定义如下枚举
[TypeConverter(typeof(DisplayEnumConverter))]public enum MyEnum{[Display(Name = "无")]None,[Display(Name = "第一个")]First,[Display(Name = "第二个")]Second,[Display(Name = "第三个")]Third}其中DisplayEnumConverter是一个TypeConverter，继承自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、环境
VS2022
四、示例
页面上定义一个ComboxBox并绑定该枚举
<ComboBox ItemsSource="{h:GetEnumSource EnumType={x:Type local:MyEnum}}"/>对GetEnumSource具体实现参考文章：示例:WPF中绑定枚举到ComboBox的方式-CSDN博客
显示效果如下
