Encapsulate Downcast

• Jun 07, 2019

Changes the return type of a method to the type that all callers downcast to, removing typecasting at calling sites.

Availability

Available from the context menu or via shortcuts:

• when the caret is on a method declaration statement, provided that the method’s return type is the ancestor of the method’s return value. Note that the caret should be on the method name or on the return type name.

Example

C#

private Object │TestMethod()
{
    return new TestClass();
}

VB.NET

Private Function │TestMethod() As Object
    Return New TestClass()
End Function

Result:

C#

private TestClass │TestMethod()
{
    return new TestClass();
}

VB.NET

Private Function │TestMethod() As TestClass
    Return New TestClass()
End Function
