Way of Reversing strings in C#

We can Reverse a String Array or List collection in many ways:-

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
       System.Collections.Generic.List<string> list = new System.Collections.Generic.List<string>();
       list.Add("Vishal");
       list.Add("Rajesh");
       list.Add("Pooja");
       list.Add("Vipin");
            
      //1st Way using Reverse method 
       list.Reverse();

       foreach (string value in list)
       {
           Response.Write("<br/>" + value);
       }

       //2nd Way 
       string[] str_names = new string[4] { "Vishal", "Rajesh", "Pooja", "Vipin" };

       if (str_names != null)
       {
                if (str_names.Length > 0)
                {
                    for (int index = str_names.Length - 1; index >= 0; index--)
                    {
                        Response.Write("<br/>" + str_names[index]);
                    }
                }
       }

       //3rd Way 
       string names = "Vishal,Rajesh,Pooja,Vipin";
       string[] comma_sep = names.Split(',');

       if (comma_sep != null)
       {
           if (comma_sep.Length > 0)
           {
                    for (int index = comma_sep.Length - 1; index >= 0; index--)
                    {
                        Response.Write("<br/>" + comma_sep[index]);
                    }
                }
           }
       }
    }

Output would be:-
Vipin
Pooja
Rajesh
Vishal
