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.
Assembly: mscorlib (in mscorlib.dll)
Property Value
Type: System::Booleantrue if access to this field is exactly described by FieldAttributes::Family; otherwise, false.
Implements
_FieldInfo::IsFamilyThe 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.
Note |
|---|
The Visual Basic and C# languages cannot define fields with FieldAttributes::FamANDAssem visibility; that access level appears only in the C++ example. |
