这是我的代码。它抛出异常“'MyEnum.CommonCoreStandard'类型的对象无法转换为'System.Nullable`1 [System.Byte]'类型。” 同时设置第二个属性“Prop2”的值。我正在使用反射的概念将一种类型“BlEntity”转换为另一种类型“UiEntity”
public class BlEntity
{
//CommonCoreStandard is an enum
public CommonCoreStandard Prop1 { get; set; }
public CommonCoreStandard? Prop2 { get; set; }
}
public class UiEntity
{
public byte Prop1 { get; set; }
public byte? Prop2 { get; set; }
}
public void ConvertBlToUi()
{
var source = new BlEntity(CommonCoreStandard.KeyIdeasAndDetails, CommonCoreStandard.IntegrationOfKnowledge);
var target = new UiEntity();
TypeConverter.ConvertBlToUi(source,target);
}
public static void ConvertBlToUi<TBl, TUi>(TBl entitySource, TUi entityTarget)
{
var blProperties = typeof(TBl).GetProperties().Select(p => new { Name = p.Name.ToLower(), Property = p }).ToArray();
var uiProperties = typeof(TUi).GetProperties().Select(p => new { Name = p.Name.ToLower(), Property = p });
foreach (var uiProperty in uiProperties)
{
var value = blProperty.Property.GetValue(entitySource);
uiProperty.Property.SetValue(entityTarget, value);
}
}
