Question

I am having a bit of trouble figuring out the exact syntax to use string.compare in the Where clause of a linq query. Below is what I have so far.

filteredApplications = AllApplications.Where(x => x.Name.Contains(string.Compare(x.Name, txtSearch.Text, StringComparison.OrdinalIgnoreCase))).ToList();

Is this even possible or am I barking up the wrong tree?

If you want to check to see if Name contains the search text:

AllApplications.Where(x => x.Name.ToUpperInvariant().Contains(txtSearch.Text.ToUpperInvariant()))).ToList();

If you want to check for equality:

AllApplications.Where(x => string.Equals(x.Name, txtSearch.Text, StringComparison.OrdinalIgnoreCase)).ToList();

In your original query, you were checking to see if x.Name contains the result of string.Compare. I assume you weren’t trying to do this, since string.Compare returns an integer. string.Compare is used primarily for determining sort order.
