ThenBy - Comparer

Query

public void Linq36()
{
    string[] words = { "aPPLE", "AbAcUs", "bRaNcH", "BlUeBeRrY", "ClOvEr", "cHeRry" };
  
    var sortedWords =
        words.OrderBy(a => a.Length)
             .ThenBy(a => a, new CaseInsensitiveComparer());
  
    ObjectDumper.Write(sortedWords);
}

Lambda Expression

public void Linq36()
{
    string[] words = { "aPPLE", "AbAcUs", "bRaNcH", "BlUeBeRrY", "ClOvEr", "cHeRry" };
 
    var sortedWords =
        words.OrderBy(a => a.Length)
             .ThenBy(a => a, new CaseInsensitiveComparer());
 
    // Another way.
    var sortedWords2 = words.OrderBy(word => word.Length);
    var sortedWords3 = sortedWords2.ThenBy(a => a, new CaseInsensitiveComparer());
 
    ObjectDumper.Write(sortedWords);
 
    ObjectDumper.Write(sortedWords3);
}

Utility Method

public class CaseInsensitiveComparer : IComparer
{
    public int Compare(string x, string y)
    {
        return string.Compare(x, y, StringComparison.OrdinalIgnoreCase);
    }
}

Output
