String.ToString Method

Returns this instance of String; no actual conversion is performed.

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

'Declaration
Public Overrides Function ToString As String

Return Value

Type: System.String
The current string.

Because this method simply returns the current string unchanged, there is no need to call it directly. It is usually called implicitly in a composite formatting operation, as the example shows.

The following example demonstrates the ToString method. Note that the example does not explicitly call the ToString method. Instead, the method is called implicitly by the composite formatting feature.

Imports System
 _

Class stringToString

   Public Shared Sub Main()
      Dim str1 As [String] = "123" 
      Dim str2 As [String] = "abc"

      Console.WriteLine("Original str1: {0}", str1)
      Console.WriteLine("Original str2: {0}", str2)
      Console.WriteLine("str1 same as str2?: {0}", [Object].ReferenceEquals(str1, str2))

      str2 = str1.ToString()
      Console.WriteLine()
      Console.WriteLine("New str2:      {0}", str2)
      Console.WriteLine("str1 same as str2?: {0}", [Object].ReferenceEquals(str1, str2))
   End Sub 'Main
End Class 'Sample

'This code produces the following output: 
'Original str1: 123 
'Original str2: abc 
'str1 same as str2?: False 

'New str2:      123 
'str1 same as str2?: True 
'
