string.Format中的BUG

 public class Outer<T>
    {
        public class Inner<U, V>
        {
            static Inner()
            {
                System.Web.HttpContext.Current.Response.Write("<br>");
                System.Web.HttpContext.Current.Response.Write("Inner:");
                string t = typeof(T).Name;
                string u = typeof(U).Name;
                string v = typeof(V).Name;
                string str = string.Format("   Outer<{0}>.Inner<{1},{2}>  ", typeof(T).Name, typeof(U).Name, typeof(V).Name);
                System.Web.HttpContext.Current.Response.Write(str);
                System.Web.HttpContext.Current.Response.Write("<br>");
              
            }
            public static void DummyMethod()
            { 
             
            }
        }


    }
   测试数据：
   Outer<int>.Inner<string, DateTime>.DummyMethod();
       Outer<string>.Inner<int, int>.DummyMethod();
       Outer<object>.Inner<string, object>.DummyMethod();
       Outer<string>.Inner<string, object>.DummyMethod();
       Outer<object>.Inner<object, string>.DummyMethod();
       Outer<string>.Inner<int, int>.DummyMethod();
 结果：

　　Inner: Outer.Inner

　　Inner: Outer.Inner

　　Inner: Outer.Inner

　　Inner: Outer.Inner

　　Inner: Outer.Inner

  实际要求结果：

   Inner: Outer<Int32>.Inner<String,DateTime>

　　Inner: Outer<String>.Inner<Int32,Int32>

　　Inner: Outer<Object>.Inner<String,Object>

　　Inner: Outer<String>.Inner<String,Object>
　　Inner: Outer<Object>.Inner<Object,String>
