C# Type Conversion Methods Example

using System;

namespace ConsoleApplication1 {
  class Program {
    static void Main(string[] args) {
      Console.WriteLine("VAL :" + Convert.ToChar("A"));

      Console.WriteLine("VAL :" + Convert.ToByte("255"));
      Console.WriteLine("VAL :" + Convert.ToSByte("127"));

      Console.WriteLine("VAL :" + Convert.ToInt16("-12345"));
      Console.WriteLine("VAL :" + Convert.ToInt32("-123456"));
      Console.WriteLine("VAL :" + Convert.ToInt64("-123456789"));

      Console.WriteLine("VAL :" + Convert.ToUInt16("12345"));
      Console.WriteLine("VAL :" + Convert.ToUInt32("123456"));
      Console.WriteLine("VAL :" + Convert.ToUInt64("123456789"));

      Console.WriteLine("VAL :" + Convert.ToSingle("3.14"));
      Console.WriteLine("VAL :" + Convert.ToDouble("3.14"));
      Console.WriteLine("VAL :" + Convert.ToDecimal("3.14"));


VAL :255
VAL :127
VAL :-12345 
VAL :-123456
VAL :-123456789 
VAL :12345
VAL :123456 
VAL :123456789
