Check the MinValue and MaxValue

 
using System;
class MinAndMax {
    public static void Main() {
        Console.WriteLine("sbyte:   {0} to {1}", sbyte.MinValue,sbyte.MaxValue);
        Console.WriteLine("byte:    {0} to {1}", byte.MinValue,byte.MaxValue);
        Console.WriteLine("short:   {0} to {1}", short.MinValue,short.MaxValue);
        Console.WriteLine("ushort:  {0} to {1}", ushort.MinValue,ushort.MaxValue);
        Console.WriteLine("int:     {0} to {1}", int.MinValue,int.MaxValue);
        Console.WriteLine("uint:    {0} to {1}", uint.MinValue,uint.MaxValue);
        Console.WriteLine("long:    {0} to {1}", long.MinValue,long.MaxValue);
        Console.WriteLine("ulong:   {0} to {1}", ulong.MinValue,ulong.MaxValue);
        Console.WriteLine("float:   {0} to {1}", float.MinValue,float.MaxValue);
        Console.WriteLine("double:  {0} to {1}", double.MinValue,double.MaxValue);
        Console.WriteLine("decimal: {0} to {1}", decimal.MinValue,decimal.MaxValue);
    }
}

Examining a Currently Running Process for Type Information

using System;
using System.Reflection;
using System.Diagnostics;
   
class AssemType {
  public static void Main(string[] args) {
       Process p = Process.GetCurrentProcess();
       string assemblyName = p.ProcessName + ".exe";
       Console.WriteLine("Examining : {0}", assemblyName);
       Assembly a = Assembly.LoadFrom(assemblyName);
   
       Type[] types = a.GetTypes();
       foreach(Type t in types)
       {
            Console.WriteLine("\nType : {0}",t.FullName);
            Console.WriteLine("\tBase class: {0}",t.BaseType.FullName);
       }
  }
}

Querying Type Information by Name

using System;
using System.Reflection;
   
class NameType
{
  public static void Main()
  {
        Type t = Type.GetType("System.String");
        Console.WriteLine("Name : {0}",t.Name);
        Console.WriteLine("Underlying System Type : {0}",t.UnderlyingSystemType);
        Console.WriteLine("Is Class : {0}",t.IsClass);
  }
}

Querying Type Information Using the Instance of an Object

using System;
using System.Reflection;
   
class InstanceType
{
  public static void Main()
  {
       String myVar = "a string";
       Type t = myVar.GetType();
       Console.WriteLine("Name : {0}",t.Name);
       Console.WriteLine("Underlying System Type: {0}",t.UnderlyingSystemType);
       Console.WriteLine("Is Class : {0}",t.IsClass);
  }
}
