Exemples

L’exemple de code suivant utilise la GetItemProperties méthode pour retourner un PropertyDescriptorCollection. L’exemple imprime la valeur et la Name valeur du courant DataColumn à l’aide de la GetValue méthode du PropertyDescriptor.

void ShowGetItemProperties()
{
   
   // Create a new DataTable and add two columns.
   DataTable^ dt = gcnew DataTable;
   dt->Columns->Add( "Name", Type::GetType( "System.String" ) );
   dt->Columns->Add( "ID", Type::GetType( "System.String" ) );
   
   // Add a row to the table.
   DataRow^ dr = dt->NewRow();
   dr[ "Name" ] = "Ann";
   dr[ "ID" ] = "AAA";
   dt->Rows->Add( dr );
   PropertyDescriptorCollection^ myPropertyDescriptors = this->BindingContext[ dt ]->GetItemProperties();
   PropertyDescriptor^ myPropertyDescriptor = myPropertyDescriptors[ "Name" ];
   Console::WriteLine( myPropertyDescriptor->Name );
   Console::WriteLine( myPropertyDescriptor->GetValue( dt->DefaultView[ 0 ] ) );
}

private void ShowGetItemProperties()
{
   // Create a new DataTable and add two columns.
   DataTable dt = new DataTable();
   dt.Columns.Add("Name", Type.GetType("System.String"));
   dt.Columns.Add("ID", Type.GetType("System.String"));
   // Add a row to the table.
   DataRow dr = dt.NewRow();
   dr["Name"] = "Ann";
   dr["ID"] = "AAA";
   dt.Rows.Add(dr);

   PropertyDescriptorCollection myPropertyDescriptors = 
   this.BindingContext[dt].GetItemProperties();
   PropertyDescriptor myPropertyDescriptor = 
   myPropertyDescriptors["Name"];
   Console.WriteLine(myPropertyDescriptor.Name);
   Console.WriteLine(myPropertyDescriptor.GetValue
   (dt.DefaultView[0]));
}

Private Sub ShowGetItemProperties()
   ' Create a new DataTable and add two columns.
   Dim dt As New DataTable()
   dt.Columns.Add("Name", Type.GetType("System.String"))
   dt.Columns.Add("ID", Type.GetType("System.String"))
   ' Add a row to the table.
   Dim dr As DataRow = dt.NewRow()
   dr("Name") = "Ann"
   dr("ID") = "AAA"
   dt.Rows.Add(dr)
     
   Dim myPropertyDescriptors As PropertyDescriptorCollection = _
   Me.BindingContext(dt).GetItemProperties()
   Dim myPropertyDescriptor As PropertyDescriptor = myPropertyDescriptors("Name")
   Console.WriteLine(myPropertyDescriptor.Name)
   Console.WriteLine(myPropertyDescriptor.GetValue(dt.DefaultView(0)))

Exemples

L’exemple de code suivant utilise la GetItemProperties méthode pour retourner une PropertyDescriptorCollection valeur pour un BindingManagerBase. L’exemple imprime ensuite les Name éléments et PropertyType les éléments de chaque PropertyDescriptor collection.

void PrintPropertyDescriptions( BindingManagerBase^ b )
{
   Console::WriteLine( "Printing Property Descriptions" );
   PropertyDescriptorCollection^ ps = b->GetItemProperties();
   for ( int i = 0; i < ps->Count; i++ )
   {
      Console::WriteLine( "\t{0}\t{1}", ps[ i ]->Name, ps[ i ]->PropertyType );

   }
}

private void PrintPropertyDescriptions(BindingManagerBase b)
{
   Console.WriteLine("Printing Property Descriptions");
   PropertyDescriptorCollection ps = b.GetItemProperties();
   for(int i = 0; i < ps.Count; i++)
   {
      Console.WriteLine("\t" + ps[i].Name + "\t" + ps[i].PropertyType);
   }
}

Private Sub PrintPropertyDescriptions(b As BindingManagerBase)
    Console.WriteLine("Printing Property Descriptions")
    Dim ps As PropertyDescriptorCollection = b.GetItemProperties()
    Dim i As Integer
    For i = 0 To ps.Count - 1
        Console.WriteLine((ControlChars.Tab & ps(i).Name & ControlChars.Tab & ps(i).PropertyType.ToString))
