MethodBase::IsFamily Property
Gets a value indicating whether the visibility of this method or constructor is described by MethodAttributes::Family; that is, the method or constructor is visible only within its class and derived classes.
Assembly: mscorlib (in mscorlib.dll)
Property Value
Type: System::Booleantrue if access to this method or constructor is exactly described by MethodAttributes::Family; otherwise, false.
The visibility of a method or constructor is exactly described by MethodAttributes::Family if the only visibility modifier is protected. This property is false for methods that are protected internal in C# (Protected Friend in Visual Basic, protected public in C++); use the IsFamilyOrAssembly property to identify such methods.
The following code example defines methods with varying levels of visibility, and displays the values of their IsAssembly, IsFamily, IsFamilyOrAssembly, and IsFamilyAndAssembly properties.
Note |
|---|
The Visual Basic and C# languages cannot define methods with MethodAttributes::FamANDAssem visibility; that access level appears only in the C++ example. |
