two loops should do it.  Note that this was coded by hand so there may be a couple of compiler errors.

int m = DateTime.Now.Month;

for (int y = DateTime.Now.Year; y <= DateTime.Now.Year + 12; y++)
{
  while (m <= 12)
  {
     string val = String.Format("{0:D2}/{1}", m, y.ToString().Substring(2,2));   
    //add val to dropdown list.
    m++;
  }
   m = 1;
}

..why not just have two dropdowns?  ..usually it's one dropdown for months, one for years.. on most websites.

Nowadays, monitoring is a mixture of tools, systems, and codes—making it a very complex process. And with this complexity, comes variables for failure. Get DZone’s new Guide to Performance to learn how to proactively find these variables and solve them before a disruption occurs.

Here's an alternative without the need for 2 loops - just use the AddMonths() method:

DateTime expiryDate = DateTime.Today;

// Loop through for 36 months
for (int i = 0; i < 36; i++)
{
	// Add the value to your dropdown
	comboBoxExpiryDate.Items.Add((object)expiryDate.ToString("MM/yy"));
	
	// Add a month
	expiryDate = expiryDate.AddMonths(1);
}

And here is an example that uses linq:
foreach (var cc in (from d in Enumerable.Range(0, 144) let now = DateTime.Now.AddMonths(d) select now.ToString("MM/yy")))
	comboBoxExpiryDate.Items.Add(cc);
