Using DataGridViewRowCollection object in LINQ

Question

I\'d like to use a DataGridViewRowCollection in a LINQ expression using extension methods and lambda expressions. Unfortunately, the extension methods are for t

Answer 1

Yes, do this:

var rows = yourDataGridViewRowCollection
               .Cast<DataGridViewRow>()
               .Where(row => row.index > 4);

This uses the Enumerable.Cast extension method:

The Cast<TResult>(IEnumerable) method enables the standard query operators to be invoked on non-generic collections by supplying the necessary type information. For example, ArrayList does not implement IEnumerable<T>, but by calling Cast<TResult>(IEnumerable) on the ArrayList object, the standard query operators can then be used to query the sequence.
