How to get index using LINQ? [duplicate]

Question

Given a datasource like that:

var c = new Car[] {   new Car{ Color="Blue", Price=28000},   new Car{ Color="Red", Price=54000},   new Car{ Color="Pink", Price=9999},   // .. }; 

How can I find the index of the first car satisfying a certain condition with LINQ?

EDIT:

I could think of something like this but it looks horrible:

int firstItem = someItems.Select((item, index) => new     {         ItemName = item.Color,         Position = index     }).Where(i => i.ItemName == "purple")       .First()       .Position; 

Will it be the best to solve this with a plain old loop?

Answer 1

myCars.Select((v, i) => new {car = v, index = i}).First(myCondition).index; 

or the slightly shorter

myCars.Select((car, index) => new {car, index}).First(myCondition).index; 

or the slightly shorter shorter

myCars.Select((car, index) => (car, index)).First(myCondition).index;
