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 bool IsFamilyAndAssembly { get; }

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.


using System;
using System.Reflection;

public class Example
{
    public void m_public() {}
    internal void m_internal() {}
    protected void m_protected() {}
    protected internal void m_protected_public() {}

    public static void Main()
    {
        Console.WriteLine("\n{0,-30}{1,-18}{2}", "", "IsAssembly", "IsFamilyOrAssembly"); 
        Console.WriteLine("{0,-21}{1,-18}{2,-18}{3}\n", 
            "", "IsPublic", "IsFamily", "IsFamilyAndAssembly");

        foreach (MethodBase m in typeof(Example).GetMethods(
            BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.Public))
        {
            if (m.Name.Substring(0, 1) == "m")
            {
                Console.WriteLine("{0,-21}{1,-9}{2,-9}{3,-9}{4,-9}{5,-9}", 
                    m.Name,
                    m.IsPublic,
                    m.IsAssembly,
                    m.IsFamily,
                    m.IsFamilyOrAssembly,
                    m.IsFamilyAndAssembly
                );
            }
        }
    }
}
