I have an ArrayList that contains,

[0] = \"1\"
[1] = \"10\"
[2] = \"2\"
[3] = \"15\"
[4] = \"17\"
[5] = \"5\"
[6] = \"6\"
[7] = \"27\"
[8] = \"8\"
[9] = \"9\"

    This is the safest way

    aryList is your ArrayList instance 

                    object[] list = aryList.ToArray();
                Array.Sort
                    (
                        list,
                        delegate(object x, object y)
                        {
                            int a = 0, b = 0;
                            if (x == y) return 0;
                            if (x == null || y == null)
                                return x == null ? -1 : 1;
                            int.TryParse(x.ToString(), out a);
                            int.TryParse(y.ToString(), out b);
                            return a.CompareTo(b);
                        }
                    );



    result saved into "list" object array
    
    
    
             
    
                                                        
    
            
            
    
              
                
                0
