How to get "drop down button" size of ComboBox in C# winforms

How can I get the size of the DropDown Button on a ComboBox?

For anyone unsure of what I mean, it is the Button usually found on the right hand side of a ComboBox containing a downward facing arrow. When clicked this expands the DropDown section.

For further clarification, it is the button in the red circle in the below image.

For such constants you can use GetSystemMetrics API function; C# quick analogue is SystemInformation class:

  using System.Windows.Forms;

  ...

  int arrowWidth = SystemInformation.VerticalScrollBarWidth;
