Beberapa informasi terkait produk prarilis yang dapat diubah secara signifikan sebelum dirilis. Microsoft tidak memberikan jaminan, tersirat maupun tersurat, sehubungan dengan informasi yang diberikan di sini.

Mendapatkan nama jenis yang sepenuhnya memenuhi syarat, termasuk namespace layanannya tetapi bukan assembly-nya.

public:
 abstract property System::String ^ FullName { System::String ^ get(); };

public abstract string FullName { get; }

public abstract string? FullName { get; }

member this.FullName : string

Public MustOverride ReadOnly Property FullName As String

Nilai Properti

String

Nama jenis yang sepenuhnya memenuhi syarat, termasuk namespace layanannya tetapi bukan assembly-nya; atau null jika jenis tidak dapat diwakili oleh nama yang sepenuhnya memenuhi syarat. Jenis yang tidak dapat diwakili oleh nama yang sepenuhnya memenuhi syarat termasuk jenis yang berisi parameter generik yang tidak terselesaikan (ContainsGenericParameters adalah true) dan jenis yang berisi penunjuk fungsi.

Penerapan

FullName

Contoh

Contoh berikut menampilkan nama lengkap jenis yang ditentukan.

using System;
class TestFullName
{
public static void Main()
    {
    Type t = typeof(Array);
    Console.WriteLine("The full name of the Array type is {0}.", t.FullName);
    }
}

/* This example produces the following output:

The full name of the Array type is System.Array.
 */

open System

let t = typeof<Array>
printfn $"The full name of the Array type is {t.FullName}."

(* This example produces the following output:

The full name of the Array type is System.Array.
 *)

Class TestFullName
   
    Public Shared Sub Main()
        Dim t As Type = GetType(Array)
        Console.WriteLine("The full name of the Array type is {0}.", t.FullName)
    End Sub
End Class

' This example produces the following output:
'
'The full name of the Array type is System.Array.
'

Keterangan

Misalnya, nama jenis yang String sepenuhnya memenuhi syarat adalah System.String. Berbeda dengan nama assembly-qualified yang dikembalikan oleh AssemblyQualifiedName properti , yang terdiri dari nama lengkap ditambah nama rakitan lengkap.

Jika jenis saat ini mewakili jenis generik tertutup, argumen jenis dalam string yang dikembalikan oleh FullName properti memenuhi syarat dengan nama rakitan lengkapnya, meskipun representasi string dari jenis generik itu sendiri tidak memenuhi syarat dengan nama rakitan lengkapnya. Contoh berikut mengilustrasikan perbedaan dalam properti FullName untuk jenis yang mewakili definisi jenis generik dan yang mewakili jenis generik tertutup.

using System;
using System.Collections.Generic;

public class Example
{
   public static void Main()
   {
      Type t = typeof(List<>);
      Console.WriteLine(t.FullName);
      Console.WriteLine();

      List<String> list = new List<String>();
      t = list.GetType();
      Console.WriteLine(t.FullName);
   }
}

// ResizeArray<'T> is an F# type abbreviation for System.Collection.Generic.List<'T>

      Dim t As Type = GetType(List(Of))

Objek saat ini Type mewakili parameter jenis jenis generik.

Contoh berikut mengambil parameter jenis jenis Nullable<T> dan mencoba menampilkan propertinya FullName .

Objek saat ini Type mewakili jenis array, jenis penunjuk, atau byref jenis yang didasarkan pada parameter jenis generik.

Contoh berikut mendefinisikan jenis generik, Generictype1<T>, dengan tiga metode: Display(T[]), yang diteruskan array jenis T; HandleT(T), yang diteruskan objek T; dan ChangeValue(ref T), yang diteruskan objek T berdasarkan referensi. Karena C# dan Visual Basic tidak memungkinkan kami untuk mendefinisikan T sebagai penunjuk dalam HandleT metode , kita harus memanggil MakePointerType metode pada Type objek yang mewakili jenis parameter metode untuk membuat penunjuk ke jenis generik. Output dari contoh menunjukkan bahwa dalam ketiga kasus, FullName propertinya adalah null.

   public void Display(T[] elements)
