MethodBase.IsFamilyOrAssembly Property

Gets a value indicating whether the potential visibility of this method or constructor is described by MethodAttributes.FamORAssem; that is, the method or constructor can be called by derived classes wherever they are, and by classes in the same assembly.

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

abstract IsFamilyOrAssembly : bool with get 
override IsFamilyOrAssembly : bool with get

Property Value

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

If a type member has MethodAttributes.FamORAssem visibility, it can be called from any member in a derived class or any member in the same assembly, but not from any other type.

The actual visibility of a method is limited by the visibility of its type. The IsFamilyOrAssembly property might be true for a method, but if it is a method of a private nested type then the method is not visible outside the containing type.

The visibility of a method or constructor is exactly described by MethodAttributes.FamORAssem if the visibility modifier is protected internal in C# (Protected Friend in Visual Basic, protected public in 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.

No code example is currently available or this language may not be supported.
