FieldInfo.IsFamilyAndAssembly Property

Definition

Namespace:

System.Reflection

Assemblies:

netstandard.dll, System.Runtime.dll

Source:

FieldInfo.cs

Gets a value indicating whether the visibility of this field is described by FamANDAssem; that is, the field can be accessed from derived classes, but only if they are in the same assembly.

C#

public bool IsFamilyAndAssembly { get; }

Property Value

Boolean

true if access to this field is exactly described by FamANDAssem; otherwise, false.

Examples

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

C#

using System;
using System.Reflection;

public class Example
{
    public int f_public;
    internal int f_internal;
    protected int f_protected;
    protected internal int f_protected_public;
    private protected int f_private_protected;

    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 (FieldInfo f in typeof(Example).GetFields(
            BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.Public))
        {
            Console.WriteLine("{0,-21}{1,-9}{2,-9}{3,-9}{4,-9}{5,-9}",
                f.Name,
                f.IsPublic,
                f.IsAssembly,
                f.IsFamily,
                f.IsFamilyOrAssembly,
                f.IsFamilyAndAssembly
            );
        }
    }
}

/* This code example produces output similar to the following:

                              IsAssembly        IsFamilyOrAssembly
                     IsPublic          IsFamily          IsFamilyAndAssembly

f_public             True     False    False    False    False
f_internal           False    True     False    False    False
f_protected          False    False    True     False    False
f_protected_public   False    False    False    True     False
f_private_protected  False    False    False    False    True
 */

Remarks

If a field has FamANDAssem level visibility, it can be called from any member in a derived class that is also in the same assembly, but not from any other type.

The visibility of a field is exactly described by FieldAttributes.FamANDAssem if the visibility modifier is private protected in C#, Private Protected in Visual Basic, or protected private in C++.
