Examples

The following code example uses the Count property to print the number of properties on button1. It requires that button1 and textBox1 have been instantiated on a form.

private:
   void GetCount()
   {
      // Creates a new collection and assign it the properties for button1.
      PropertyDescriptorCollection^ properties = TypeDescriptor::GetProperties( button1 );
      
      // Prints the number of properties on button1 in a textbox.
      textBox1->Text = properties->Count.ToString();
   }
private void GetCount() {
    // Creates a new collection and assign it the properties for button1.
    PropertyDescriptorCollection properties = TypeDescriptor.GetProperties(button1);
 
    // Prints the number of properties on button1 in a textbox.
    textBox1.Text = properties.Count.ToString();
 }

Private Sub GetCount()
    ' Creates a new collection and assign it the properties for button1.
    Dim properties As PropertyDescriptorCollection = TypeDescriptor.GetProperties(button1)
       
    ' Prints the number of properties on button1 in a textbox.
    textBox1.Text = properties.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. Because the collection is zero-based, be sure to use Count - 1 as the upper boundary of the loop.
