Contoh

Contoh kode berikut menyediakan contoh INameCreationService.CreateName implementasi metode. Metode ini dapat membuat nama berdasarkan nama jenis tertentu yang unik untuk nama komponen dalam kontainer yang ditentukan.

// Creates an identifier for a particular data type that does not conflict 
// with the identifiers of any components in the specified collection.
virtual String^ CreateName( System::ComponentModel::IContainer^ container, System::Type^ dataType )
{
   // Create a basic type name string.
   String^ baseName = dataType->Name;
   int uniqueID = 1;
   bool unique = false;

   // Continue to increment uniqueID numeral until a 
   // unique ID is located.
   while (  !unique )
   {
      unique = true;

      // Check each component in the container for a matching 
      // base type name and unique ID.
      for ( int i = 0; i < container->Components->Count; i++ )
      {
         // Check component name for match with unique ID string.
         if ( container->Components[ i ]->Site->Name->StartsWith( String::Concat( baseName, uniqueID ) ) )
         {
            // If a match is encountered, set flag to recycle 
            // collection, increment ID numeral, and restart.
            unique = false;
            uniqueID++;
            break;
         }
      }
   }

   return String::Concat( baseName, uniqueID );
}

// Creates an identifier for a particular data type that does not conflict 
// with the identifiers of any components in the specified collection.
public string CreateName(System.ComponentModel.IContainer container, System.Type dataType)
{
    // Create a basic type name string.
    string baseName = dataType.Name;
    int uniqueID = 1;

    bool unique = false;            
    // Continue to increment uniqueID numeral until a 
    // unique ID is located.
    while( !unique )
    {
        unique = true;
        // Check each component in the container for a matching 
        // base type name and unique ID.
        for(int i=0; i<container.Components.Count; i++)
        {
            // Check component name for match with unique ID string.
            if( container.Components[i].Site.Name.StartsWith(baseName+uniqueID.ToString()) )
            {
                // If a match is encountered, set flag to recycle 
                // collection, increment ID numeral, and restart.
                unique = false;
                uniqueID++;
                break;
            }
        }
    }
    
    return baseName+uniqueID.ToString();
}

' Creates an identifier for a particular data type that does not conflict 
' with the identifiers of any components in the specified collection
Public Function CreateName(ByVal container As System.ComponentModel.IContainer, ByVal dataType As System.Type) As String Implements INameCreationService.CreateName

        Dim i As Integer
        For i = 0 To container.Components.Count - 1
            ' Check component name for match with unique ID string.
            If container.Components(i).Site.Name.StartsWith((baseName + uniqueID.ToString())) Then
                ' If a match is encountered, set flag to recycle

                Exit For
            End If
        Next i
    End While

    Return baseName + uniqueID.ToString()
End Function

Keterangan

Metode ini mengembalikan nama untuk objek baru yang unik dalam kontainer yang ditentukan.

Catatan Bagi Implementer

Jenis layanan ini sering diimplementasikan untuk membuat nama objek unik dari nama jenis data, sering ditambahkan dengan angka yang memungkinkan nama menjadi pengidentifikasi unik. Misalnya, ListBox1 untuk ListBox objek .
