MethodBase.IsAssembly 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 potential visibility of this method or constructor is described by MethodAttributes.Assembly; that is, the method or constructor is visible at most to other types in the same assembly, and is not visible to derived types outside the assembly.
Assembly: mscorlib (in mscorlib.dll)
Property Value
Type: System.Booleantrue if the visibility of this method or constructor is exactly described by MethodAttributes.Assembly; otherwise, false.
The actual visibility of a method is limited by the visibility of its type. The IsAssembly property might be true for a method, but if it is a method of a private nested type, the method is not visible outside the containing type.
The visibility of a method or constructor is exactly described by MethodAttributes.Assembly if the only visibility modifier is internal (Friend in Visual Basic). This property is false for methods that are protected internal in C# (Protected Friend in Visual Basic, protected public in C++); use the IsFamilyOrAssembly property to identify such methods.
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. |
