Type.ToString Method ()

Returns a String representing the name of the current Type.

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

Public Overrides Function ToString As String

Return Value

Type: System.String

A String representing the name of the current Type.

This method returns the fully qualified common language runtime namespace and name for all primitive types. For example, the C# instruction, (long)0.Type().ToString() returns "System.Int64" instead of merely "Int64".

If the current Type represents a generic type, the type and its type arguments are qualified by namespace and by nested type, but not by assembly. If the current Type represents a type parameter in the definition of a generic type or generic method, this method returns the unqualified name of the type parameter.

This following example demonstrates a use of the Namespace and Module properties and the ToString method of Type.

Namespace MyNamespace
    Class [MyClass]
    End Class 
End Namespace 

Public Class Example
    Public Shared Sub Main()
         Dim myType As Type = GetType(MyNamespace.MyClass)
         Console.WriteLine(", myType)
         ' Get the namespace of the MyClass class.
         Console.WriteLine("   Namespace: {0}.", myType.Namespace)
         ' Get the name of the module.
         Console.WriteLine("   Module: {0}.", myType.Module)
         ' Get the fully qualified type name.
         Console.WriteLine("   Fully qualified name: {0}.", myType.ToString())
    End Sub
End Class
' The example displays the following output:
'       Displaying information about MyNamespace.MyClass:
'          Namespace: MyNamespace.
'          Module: type_tostring.exe.
'          Fully qualified name: MyNamespace.MyClass.

The following example compares the strings returned by the ToString method and the Name, FullName, and AssemblyQualifiedName properties.

Imports System.Collections.Generic
Imports System.Globalization

Module Example
   Public Sub Main()
      Dim t As Type = GetType(String)
      ShowTypeInfo(t)

      t = GetType(System.Collections.Generic.List(Of))
      ShowTypeInfo(t)

      Dim list As New List(Of String)()
      t = list.GetType()
      ShowTypeInfo(t)

      Dim v As Object = 12
      t = v.GetType()
      ShowTypeInfo(t)

      t = GetType(IFormatProvider)
      ShowTypeInfo(t)

      Dim ifmt As IFormatProvider = NumberFormatInfo.CurrentInfo
      t = ifmt.GetType()
      ShowTypeInfo(t)
   End Sub

   Private Sub ShowTypeInfo(t As Type)
      Console.WriteLine("Name: {0}", t.Name)
      Console.WriteLine("Full Name: {0}", t.FullName)
      Console.WriteLine("ToString:  {0}", t.ToString())
      Console.WriteLine("Assembly Qualified Name: {0}", t.AssemblyQualifiedName)
      Console.WriteLine()
   End Sub
End Module
