EditorBrowsableAttribute is a hint to a designer indicating whether a property or method is to be displayed. You can use this type in a visual designer or text editor to determine what is visible to the user. For example, the IntelliSense engine in Visual Studio uses this attribute to determine whether to show a property or method.

In Visual C#, you can control when advanced properties appear in IntelliSense and the Properties Window with the Hide Advanced Members setting under Tools | Options | Text Editor | C#. The corresponding EditorBrowsableState is Advanced.

Note:
In Visual C#, EditorBrowsableAttribute does not suppress members from a class in the same assembly.

The following sample demonstrates how to hide a property of a class from IntelliSense by setting the appropriate value for the EditorBrowsableAttribute attribute. Build Class1 in its own assembly.

In Visual Studio, create a new Windows Application solution, and add a reference to the assembly which contains Class1. In the Form1 constructor, declare an instance of Class1, type the name of the instance, and press the period key to activate the IntelliSense drop-down list of Class1 members. The Age property does not appear in the drop-down list.

Imports System.ComponentModel

Public Class Class1

    Private ageval As Integer

    <EditorBrowsable(System.ComponentModel.EditorBrowsableState.Never)> _
    Public Property Age() As Integer

        Get
            Return ageval
        End Get

        Set(ByVal Value As Integer)
            If Not ageval.Equals(Value) Then
                ageval = Value
            End If
        End Set

    End Property

End Class
