In my application I have added a Properties.cs file which contains properties that I am would use through out the application. I am getting NullReferenceException => Object reference not set to an instance of an object. Here is the code for Properties.cs

public class Properties
{
    private static string type1;

    public static string Type1
    {
        get
        {
            return type1;
        }
        set
        {
            type1= value;
        }
    }
}

And when I access this property in one of my form I am getting error. e.g.

if (Properties.Type1.Equals(string.Empty) || Properties.Type1.Equals(null))
        {
            //// Do something
        }
