Answer 1

using System;

namespace ConsoleApplication_C_Sharp
{
    class Program
    {
        static void Main(string[] args)
        {
            Type type1 = typeof(char);
            Type type2 = typeof(int);
            Type type3 = "string".GetType();
            Type type4 = typeof(string[]);
            Type type5 = typeof(Type);

            TypeInfo(type1);
            TypeInfo(type2);
            TypeInfo(type3);
            TypeInfo(type4);
            TypeInfo(type5);
        }

        static void TypeInfo(Type type)
        {
            Console.WriteLine("Name: {0}", type.Name);
            Console.WriteLine("BaseType.Name: {0}", type.BaseType.Name);
            Console.WriteLine("IsArray: {0}", type.IsArray);
            Console.WriteLine("IsGenericType: {0}", type.IsGenericType);
            Console.WriteLine("IsSealed: {0}", type.IsSealed);
            Console.WriteLine();
        }
    }
}
