MethodBase.IsFamilyAndAssembly Property
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Gets a value that indicates 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.
Assembly: mscorlib (in mscorlib.dll)
Property Value
Type: System.Booleantrue 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 example defines methods 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 methods with MethodAttributes.FamANDAssem visibility. |
