C# sorting strings small and capital letters

Question

Is there a standard functionality which will allow me to sort capital and small letters in the following way or I should implement a custom comparator:

stude         


        

Answer 1

I believe you want to group those strings which starts with lower case and upper case, then sort them separately.

You can do:

list = list.Where(r => char.IsLower(r[0])).OrderBy(r => r)
      .Concat(list.Where(r => char.IsUpper(r[0])).OrderBy(r => r)).ToList();

First select those string which starts with lower case, sort them, then concatenate it with those strings which start with upper case(sort them). So your code will be:

List list = new List();
list.Add("student");
list.Add("students");
list.Add("Student");
list.Add("Students");
list = list.Where(r => char.IsLower(r[0])).OrderBy(r => r)
      .Concat(list.Where(r => char.IsUpper(r[0])).OrderBy(r => r)).ToList();
for (int i = 0; i < list.Count; i++)
    Console.WriteLine(list[i]);

and output:

student
students
Student
Students
