例

次のコード例では、メソッドを GetItemProperties 使用して PropertyDescriptorCollection. この例では、次の Name メソッドを使用して現在 DataColumn の値と値を GetValue 出力します 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)))
End Sub

例

次のコード例では、メソッドを GetItemProperties 使用して for a PropertyDescriptorCollection を BindingManagerBase返します。 次に、コレクション内のそれぞれのPropertyDescriptor出力を出力NamePropertyTypeします。

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);
   }
