implicit type conversion − these conversions are performed by c# in a type-safe manner. for example, 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.

the following example shows an explicit type conversion −

using system;

namespace typeconversionapplication {
   class explicitconversion {
      static void main(string[] args) {
         double d = 5673.74; 
         int i;
         
         // cast double to int.
         i = (int)d;
         console.writeline(i);
         console.readkey();
      }
   }
}

when the above code is compiled and executed, it produces the following result −

c# type conversion methods

c# provides the following built-in type conversion methods −

sr.no.	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.

the following example converts various value types to string type −

using system;

namespace typeconversionapplication {
   class stringconversion {
      static void main(string[] args) {
         int i = 75;
         float f = 53.005f;
         double d = 2345.7652;
         bool b = true;

         console.writeline(i.tostring());
         console.writeline(f.tostring());
         console.writeline(d.tostring());
         console.writeline(b.tostring());
         console.readkey();
            
      }
   }
}

when the above code is compiled and executed, it produces the following result −

75
53.005
2345.7652
true
