Examples

The following code example uses the Count property to print the number of properties on button1 in a text box. It assumes that button1 and textBox1 have been created on a form.

private:
   void GetCount()
   {
      // Creates a new collection and assigns it the attributes for button1.
      AttributeCollection^ attributes;
      attributes = TypeDescriptor::GetAttributes( button1 );
      
      // Prints the number of items in the collection.
      textBox1->Text = attributes->Count.ToString();
   }

private void GetCount() {
    // Creates a new collection and assigns it the attributes for button1.
    AttributeCollection attributes;
    attributes = TypeDescriptor.GetAttributes(button1);

    // Prints the number of items in the collection.
    textBox1.Text = attributes.Count.ToString();
 }

Private Sub GetCount
    ' Creates a new collection and assigns it the attributes for button 1.
    Dim attributes As AttributeCollection
    attributes = TypeDescriptor.GetAttributes(button1)
    ' Prints the number of items in the collection.
    textBox1.Text = attributes.Count.ToString
End Sub

Remarks

You can use the Count property to set the limits of a loop that iterates through a collection of objects. If the collection is zero-based, be sure to use Count - 1 as the upper boundary of the loop.
