Nullable<T>Explicit Conversion (Nullable<T> to T)

 
equivalentCodeEntityP:System.Nullable`1.Value

Defines an explicit conversion of a Nullable<T> instance to its underlying value.

Namespace:   System
Assembly:  mscorlib (in mscorlib.dll)

public static explicit operator T (
	Nullable<T> value
)

Parameters

value
Type: System.Nullable<T>

A nullable value.

Return Value

Type: T

The value of the Value property for the value parameter.

This operator supports the explicit conversion of the current Nullable<T> instance to type T, the type of Value. The syntax for such explicit conversions is language-dependent. You may also be able to perform the conversion by calling the Convert.ChangeType method.

The Explicit(Nullable<T> to T) operator enables code such as the following, which converts a Nullable(Of Int32) value to an Int32 value.

using System;

public class Example
{
   public static void Main()
   {
       var nullInt = new Nullable<int>(172);
       // Convert with CInt conversion method.
       Console.WriteLine((int)nullInt);
       // Convert with Convert.ChangeType.
       Console.WriteLine(Convert.ChangeType(nullInt, typeof(int)));
   }
}
// The example displays the following output:
//       172
//       172
