FieldInfo::IsFamily Property

 

Gets a value indicating whether the visibility of this field is described by FieldAttributes::Family; that is, the field is visible only within its class and derived classes.

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

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

Property Value

Type: System::Boolean

true if access to this field is exactly described by FieldAttributes::Family; otherwise, false.

The visibility of a field is exactly described by FieldAttributes::Family if the only visibility modifier is protected. This property is false for fields that are protected internal in C# (Protected Friend in Visual Basic, protected public in C++); use the IsFamilyOrAssembly property to identify such fields.

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

System_CAPS_noteNote

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

using namespace System;
using namespace System::Reflection;

public ref class Example
{
public:
    int f_public;
internal:
    int f_internal;
protected:
    int f_protected;
protected public:
    int f_protected_public;
protected private:
    int f_protected_private;
};

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");

    for each (FieldInfo^ f in Example::typeid->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
        );
    }
}
