duplicates

I've got a List that contains duplicates and I need to find the indexes of each.

What is the most elegant, efficient way other than looping through all the items. I'm on .NET 4.0 so LINQ is an option. I've done tons of searching and connect find anything.

Sample data:

var data = new List{"fname", "lname", "home", "home", "company"}();

I need to get the indexes of "home".

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
