Question

How do i check if a Type is a nullable enum in C# something like

Type t = GetMyType();
bool isEnum = t.IsEnum; //Type member
bool isNullableEnum = t.IsNullab         


        

Answer 1

As from C# 6.0 the accepted answer can be refactored as

Nullable.GetUnderlyingType(t)?.IsEnum == true

The == true is needed to convert bool? to bool
