Return Value

Type: System.String
The text representation of the value of the current Nullable<T> object if the HasValue property is true, or an empty string ("") if the HasValue property is false.

The following code example displays the value of the current Nullable<T> object.


// This code example demonstrates the 
// Nullable<T>.ToString method.

using System;

class Example
{
   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {
      DateTime? nullableDate;

      // Display the current date and time.
      nullableDate = DateTime.Now;
      Display(outputBlock, "1)", nullableDate);

      // Assign null (Nothing in Visual Basic) to nullableDate, then 
      // display its value.
      nullableDate = null;
      Display(outputBlock, "2)", nullableDate);
   }

   // Display the text representation of a nullable DateTime.
   public static void Display(System.Windows.Controls.TextBlock outputBlock, string title, DateTime? dspDT)
   {
      string msg = dspDT.ToString();

      outputBlock.Text += String.Format("{0} ", title);
      if (String.IsNullOrEmpty(msg))
         outputBlock.Text += "The nullable DateTime has no defined value." + "\n";
      else
         outputBlock.Text += String.Format("The current date and time is {0}.", msg) + "\n";
   }
}
