MethodBase.IsFamilyOrAssembly Property
Definition
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Gets a value indicating whether the potential visibility of this method or constructor is described by FamORAssem; that is, the method or constructor can be called by derived classes wherever they are, and by classes in the same assembly.
public:
property bool IsFamilyOrAssembly { bool get(); };public bool IsFamilyOrAssembly { get; }member this.IsFamilyOrAssembly : boolPublic ReadOnly Property IsFamilyOrAssembly As BooleanProperty Value
true if access to this method or constructor is exactly described by FamORAssem; otherwise, false.

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

Console::WriteLine("{0,-21}{1,-18}{2,-18}{3}\n",
"", "IsPublic", "IsFamily", "IsFamilyAndAssembly");
for each (MethodBase^ m in Example::typeid->GetMethods(
BindingFlags::Instance | BindingFlags::NonPublic | BindingFlags::Public))

Remarks
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++).
