Type.ToString Method ()

 

Returns a String representing the name of the current Type.

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

public override string ToString()

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.

using System;

namespace MyNamespace
{
    class MyClass
    {
    }
}

public class Example
{
    public static void Main()
    {
         Type myType = typeof(MyNamespace.MyClass);
         Console.WriteLine("Displaying information about {0}:", 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());
    }
}
// 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.

using System;
using System.Collections.Generic;
using System.Globalization;

public class Example
{
   public static void Main()
   {
      Type t = typeof(String);
      ShowTypeInfo(t);

      t = typeof(System.Collections.Generic.List<>);
      ShowTypeInfo(t);

      var list = new List<String>();
      t = list.GetType();
      ShowTypeInfo(t);

      Object v = 12;
      t = v.GetType();
      ShowTypeInfo(t);

      t = typeof(IFormatProvider);
      ShowTypeInfo(t);

      IFormatProvider ifmt = NumberFormatInfo.CurrentInfo;
      t = ifmt.GetType();
      ShowTypeInfo(t);
   }

   private static void ShowTypeInfo(Type t)
   {
      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();
   }
}
