EditorBrowsableAttribute Class

Specifies that a property or method is viewable in an editor. This class cannot be inherited.

Namespace:  System.ComponentModel
Assembly:  System (in System.dll)

public sealed class EditorBrowsableAttribute : Attribute

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.


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.

using System;
using System.ComponentModel;

namespace EditorBrowsableDemo
    public class Class1
        public Class1()
            // TODO: Add constructor logic here 

        int ageval;

        public int Age
            get { return ageval; }
                if (!ageval.Equals(value))
                    ageval = value;


Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
