Sorting a List in C#

Question

public class BatchProcess
    {
        public string process { get; set; }
        public DateTime runtime { get; set; }
        public bool running { get; set; }
    }

So I have a list of these guys - List<BatchProcess> list.

How would I sort based one each of those columns? I've heard I can do it with LINQ but I'm so bad with LINQ. How would that look?

Thanks.

You could sort by runtime, for example, via:

var orderedByRuntime = list.OrderBy(p => p.runtime);

If you wanted to sort by "process" in descending order, you can use:

var orderedByProcessDesc = list.OrderByDecending(p => p.process);

Here's an example of using LINQ (lambda syntax) to create a list that's sorted by process.

var listByProcess = list.OrderBy(bp => bp.process);

Use OrderBy:

var sortedList = list.OrderBy(p => p.runtime).ToList();

If you want to sort by all of them, as it seems this is what you are asking you can just do the following

var sorted = list.OrderBy(p => p.process).ThenBy(r => r.runtime);
