使用静态字段时键入Initialization Exception

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace TypeIntailization_Exception
{

    class TypeInit
    {
        // Static constructor
        static TypeInit()
        {

        }
        static readonly TypeInit instance = new TypeInit();
        public  static TypeInit Instance
        {
            get { return instance; }
        }
        TypeInit() { }
    }
    class TestTypeInit
    {
        static public void Main()
        {

            TypeInit t = TypeInit.Instance;

        }
    }

}
