Convert Class

In C#, the Convert class is used for converting a base data type to another base data type i.e., it is used for type conversion. The Convert class provides a variety of static methods that are used for type conversion.

Type Conversion Methods (Convert Class Methods)

The popular type conversion (Convert class) methods are:

Method	Description
Convert.ToByte()	Converts string to 8-bit unsigned integer.
Convert.ToSByte()	Converts string to 8-bit signed integer.
Convert.ToInt16()	Converts string to 16-bit signed integer.
Convert.ToInt32()	Converts string to 32-bit signed integer.
Convert.ToInt64()	Converts string to 64-bit signed integer.
Convert.ToUInt16()	Converts string to 16-bit unsigned integer.
Convert.ToUInt32()	Converts string to 32-bit unsigned integer.
Convert.ToUInt64()	Converts string to 64-bit unsigned integer.
Convert.ToChar()	Converts string to single character.
Convert.ToString()	Converts number to string.
Convert.Single()	Converts string to 32-bit float.
Convert.Double()	Converts string to 64-bit double.
Convert.Decimal()	Converts string to 128-bit decimal.

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"));
      Console.WriteLine(Convert.ToString(125));
    }
  }
}

Output

VAL :A
VAL :255
VAL :127
VAL :-12345 
VAL :-123456
VAL :-123456789 
VAL :12345
VAL :123456 
VAL :123456789
VAL :3.14 
VAL :3.14 
VAL :3.14 
125
