如何转换IEnumerable <MySpecificEnumType> 通用IEnumerable <Enum> 在WPF（C＃）中

Question

I have a user control that uses a combobox with its source being bound to an IEnumerable of type Enum (I have several different types of user defined enums to be used in the user control, so use the generic IEnumerable<Enum> in the backing code of my user control). However, when I attempt to create the IEnumberable list in the backing code of the item using the user control, I can't convert my IEnumerable of my own enum type to the generic Enum IEnumerable .

I get the following error:

Unable to cast object of type MyEnumType[] to type System.Enum[] when I attempt to convert to Enum[] . The code giving this error is:

public IEnumberable<Enum> MyEnums { get { return (Enum[])Enum.GetValues(typeof(MySpecificEnumType)); } }

How should I convert from a list of my enum type to a list of the generic Enum type? Or should I be using a different type of IEnumerable in the backing code of my user control?

如果您确实希望获得IEnumerable<Enum> ，则可以使用Cast扩展方法：

return Enum.GetValues(typeof(MySpecificEnumType)).Cast<Enum>();
