PropertyDescriptorCollection

Eine PropertyDescriptorCollection, die die Eigenschaftenbezeichner für die Bindung darstellt.

Beispiele

Im folgenden Codebeispiel wird die GetItemProperties Methode verwendet, um eine PropertyDescriptorCollection. Im Beispiel wird der Wert und der Name Wert des aktuellen DataColumn Ausdrucks mit der GetValue Methode der 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)

Beispiele

Im folgenden Codebeispiel wird die GetItemProperties Methode verwendet, um eine PropertyDescriptorCollection für eine BindingManagerBase. Das Beispiel druckt dann die Name einzelnen PropertyType PropertyDescriptor Elemente in der Auflistung aus.

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))
