set (C# Reference)

The set keyword defines an accessor method in a property or indexer that assigns the value of the property or the indexer element. For more information and examples, see Properties (C# Programming Guide), Auto-Implemented Properties (C# Programming Guide), and Indexers (C# Programming Guide).

This is an example of a set accessor for a property named Seconds:

class TimePeriod
{
    private double _seconds;
    public double Seconds
    {
        get { return _seconds; }
        set { _seconds = value; }
    }


}

This is an example of a set accessor in an auto-implemented property:

class TimePeriod2
{
    public double Hours { get; set; }
}
