C# Type Conversion

Type conversion means, conversion of one data type to another data type. You can also call type conversion as type casting. Type conversion is of these two types in C# programming:

• explicit type conversion
• implicit type conversion

Explicit Type Conversion in C#

Explicit type conversion in C#, are done explicitly by users using the pre-defined functions. Explicit type conversion in C#, requires a cast operator.

Here is an example program, illustrating explicit type conversion in C# programming.

/* C# Type Conversion - Example Program */
		
using System;
namespace ExplicitTypeApplication 
{
   class ExplicitConv 
   {
      static void Main(string[] args) 
      {
         double dbl = 4323.74; 
         int num;
         num = (int)dbl;	// casted double to an int
         Console.WriteLine(i);
         Console.ReadKey();
      }
   }
}

It will display the following output after compile and executed the above C# program:

4323

Implicit Type Conversion in C#

Implicit type conversion in C#, are performed in a type-safe manner. For instance, conversion from smaller to larger integral types.

Methods used in Type Conversion in C#

Here are built-in methods listed, used in type conversion in C# programming:

Here is an example program, illustrates type conversion using built-in methods in C# programming. This C# program converts some values type to string type:

/* C# Type Conversion - Example Program */
		
using System;
namespace ConversionMethodsApplication 
{
	class StringConv
	{
		static void Main(string[] args)
		{
			int num = 95;
			float flt = 93.005f;
			double dbl = 9345.7652;
			bool bl = true;
			Console.WriteLine(num.ToString());
			Console.WriteLine(flt.ToString());
			Console.WriteLine(dbl.ToString());
			Console.WriteLine(bl.ToString());
			Console.ReadKey();
		}
	}
}

When the above code will compile and executed, it would produce the following output:

95
93.005
9345.7652
True
