Multiple Description Attribute in c#

DescriptionAttribute not allow to be set multiple times.

Is there any way to have such opportunity to set kind of DescriptionAttribute many times to property or enum for example.

You should be calling the base class constructor and remove the Description property. This also shows how to set the ExtraInfo property. 

public class ExtraDescriptionAttribute : DescriptionAttribute
{
    public String ExtraInfo { get; private set; }

    public ExtraDescriptionAttribute (String description, String extraInfo) : base(description)
    {
        ExtraInfo = extraInfo;
    }
}

The description attribute will now look like:

[ExtraDescriptionAttribute("Description", "ExtraInfo")]

Solution:

public class ExtraDescriptionAttribute : DescriptionAttribute
{
    private string extraInfo; public string ExtraInfo { get { return extraInfo; } set { extraInfo = value; } }
    public ExtraDescriptionAttribute(string description)
    {
        this.DescriptionValue = description;
        this.extraInfo = String.Empty;
    }
}
