This method returns a human-readable string that is culture-sensitive. For example, for an instance of the Double class whose value is zero, the implementation of Double..::.ToString might return "0.00" or "0,00" depending on the current UI culture.

The default implementation returns the fully qualified name of the type of the Object.

Notes to Implementers:

This method can be overridden in a derived class to return values that are meaningful for that type. For example, the base data types, such as Int32, implement ToString so that it returns the string form of the value that the object represents. Derived classes that require more control over the formatting of strings than ToString provides must implement IFormattable, whose ToString method uses the current thread's CurrentCulture property.

The following code example demonstrates what ToString returns.

Public Class Sample
    Public Shared Sub Main()
        ' Displays: "System.Object"
        Dim o As New Object()
        Console.WriteLine(o.ToString())
    End Sub 
End Class 

using System;

public class Sample
{
    public static void Main() {

        // Prints out: "System.Object"
        Object o = new Object();
        Console.WriteLine (o.ToString());

    }
}

#using <System.DLL>

using namespace System;
ref class Sample
{
private:
   void Method()
   {

      // Prints out: "System.Object"
      Object^ o = gcnew Object;
      Console::WriteLine( o->ToString() );
   }

};

import System.*;

public class Sample
{
    void Method()
    {
        // Prints out: "System.Object"
        Object o = new Object();
        Console.WriteLine(o.ToString());
    } //Method 
} //Sample
