Container for Jagged Arrays?

I am looking for a way to put all of my jaggedArrays into a container with a length property. I can then use
the length instead of the static int 5 shown below.  It will also allow me to add more jagged arrays to 
the container without having to change the static variable.
            string[][] jaggedArray = new string[5][];

            jaggedArray[0] = new string[] { "one", "two", "three", "four", "five", "six" };
            jaggedArray[1] = new string[] { "one", "two", "three", "four", "five", "six" };
            jaggedArray[2] = new string[] { "one", "two", "three" };
            jaggedArray[3] = new string[] { "one", "two", "three", "four" };
            jaggedArray[4] = new string[] { "one", "two", "three", "four", "five", "six" };
Thank you
