Checking delegates for null

Question

I was reading the Essential C# 3.0 book and am wondering if this is a good way to check delegates for null?:

class Thermostat
{
    public delegate void Temperat         


        

Answer 1

I just see a bit of refactoring that could be done but otherwise it looks good...

class Thermostat
{
    public delegate void TemperatureChangeHandler ( float newTemperature );

    public TemperatureChangeHandler OnTemperatureChange { get; set; }

    float currentTemperature;

    public float CurrentTemperature
    {
        get { return this.currentTemperature; }
        set
        {
                if (currentTemperature != value)
                {
                        currentTemperature = value;

                        if (this.OnTemperatureChange != null )
                        {
                                this.OnTemperatureChange.Invoke( value );
                        }
                }
        }
    }
}
