{

    protected static readonly DateTime instanceCreateTiem;

    public myClass()

       {

              //

              // TODO: Add constructor logic here

              //

       }

    //Static constructor

    static myClass()

    {

        instanceCreateTiem = DateTime.Now;

         // The following statement produces the first line of output,

         // and the line occurs only once.

         Console.WriteLine("Static constructor sets  start time to {0}",

             instanceCreateTiem.ToLongTimeString());

     }

}

//I am creating an instance of a class

//costrutorr automaticall called

myClass obj = new myClass();

In the console you will get like
