MethodBase::IsFamilyAndAssembly Property

Gets a value indicating whether the visibility of this method or constructor is described by MethodAttributes::FamANDAssem; that is, the method or constructor can be called by derived classes, but only if they are in the same assembly.

Namespace:  System.Reflection
Assembly:  mscorlib (in mscorlib.dll)

public:
virtual property bool IsFamilyAndAssembly {
	bool get () sealed;
}

Property Value

Type: System::Boolean
true if access to this method or constructor is exactly described by MethodAttributes::FamANDAssem; otherwise, false.

The visibility of a method or constructor is exactly described by MethodAttributes::FamANDAssem if the visibility modifier is protected private in C++. Methods with this visibility cannot be defined in Visual Basic or C#.

The following code example defines methods with varying levels of visibility, and displays the values of their IsAssembly, IsFamily, IsFamilyOrAssembly, and IsFamilyAndAssembly properties.

NoteNote

The Visual Basic and C# languages cannot define methods with MethodAttributes::FamANDAssem visibility; that access level appears only in the C++ example.
