Identifying a custom indexer using reflection in C#

Question

I have a class with a custom indexer like so

public string this[VehicleProperty property]
{
  // Code
}

How can I identify the custom index

Answer 1

You can also look for index parameters, using the the PropertyInfo.GetIndexParameters method, if it returns more than 0 items, it's an indexed property:

foreach (PropertyInfo pi in typeof(MyClass).GetProperties())
{
    if (pi.GetIndexParameters().Length > 0)
    {
       // Indexed property...
    }
}
