I have the following code :
PropertyInfo[] originalProperties = myType.GetProperties();
I want to exclude from originalProperties
Another option is to use:
myType.GetProperties().Except(myType.GetDefaultMembers().OfType());
GetDefaultMembers will return all the compiler generated indexers in C#. This has the advantage of not needing to reflect on each individual property in order to find out which ones are indexers.
This might not be a general solution for all allowed .NET framework languages, but I am currently not aware of any counter-examples.
