DATA TYPES CONVERSION IN C#

Type conversion is basically type casting or converting one type of data to another type. In C#, type casting has two forms:

• Implicit type conversion - these conversions are performed by C# in a type-safe manner. Examples are conversions from smaller to larger integral types and conversions from derived classes to base classes.
• Explicit type conversion - these conversions are done explicitly by users using the pre-defined functions. Explicit conversions require a cast operator.

Implicit conversion

For Example

using System;

namespace Project

{

  class Implicit

 {

    static void Main(String[] args)

   {

     double b=25.301;

    int i=(int)b;

    Console.WriteLine("Conversion to int :{o}",i);

    Console.ReadLine();

   }

 }

}

OUTPUT:

25

Following Methods for Explicit Function

S.N	Methods & Description
1	ToBoolean Converts a type to a Boolean value, where possible.
2	ToByte Converts a type to a byte.
3	ToChar Converts a type to a single Unicode character, where possible.
4	ToDateTime Converts a type (integer or string type) to date-time structures.
5	ToDecimal Converts a floating point or integer type to a decimal type.
6	ToDouble Converts a type to a double type.
7	ToInt16 Converts a type to a 16-bit integer.
8	ToInt32 Converts a type to a 32-bit integer.
9	ToInt64 Converts a type to a 64-bit integer.
10	ToSbyte Converts a type to a signed byte type.
11	ToSingle Converts a type to a small floating point number.
12	ToString Converts a type to a string.
13	ToType Converts a type to a specified type.
14	ToUInt16 Converts a type to an unsigned int type.
15	ToUInt32 Converts a type to an unsigned long type.
16	ToUInt64 Converts a type to an unsigned big integer.

For Example

using System;

namespace TypeC

{

  class Type

{

   static void Main(String[] args)

   {

    double b=123.045;

    int p=234;

    float q=25.09f;

   bool w=true;

   

   Console.WriteLine(b.ToString());

   Console.WriteLine(p.ToString());

 Console.WriteLine(q.ToString());

 Console.WriteLine(w.ToString());

  

    }

}

}

OUTPUT:

123.045

234

25.09

true
