可移植类库中的Type.BaseType

Question

• In VS2013: Create a Portable Class Library
• Target .NET Framework 4.5, Windows Phone 8.1 & Windows 8

• Write the following code:

   public class Class1 { public static Type GetBaseType(Type type) { return type.BaseType; } } 

Observe that you cannot compile: "'System.Type' does not contain a definition for 'BaseType' and no extension method 'BaseType' accepting a first argument of type 'System.Type' could be found (are you missing a using directive or an assembly reference?)"

Strange since the MSDN documentation clearly states this property should be present: http://msdn.microsoft.com/en-us/library/system.type.basetype(v=vs.110).aspx

Answer 1

It is not available in WinRT apps. Properties and methods supported in WinRT have this mentioned explicitly (look at the store icon) - http://msdn.microsoft.com/en-us/library/system.type(v=vs.110).aspx

This answer provides a workaround for WinRT - What is the equivalent to Type.BaseType in WinRT?

Type.GetTypeInfo().BaseType
