Hi,
    I have a C# StringBuilder with the below strings:

2.1.1 ICSS
2.1.1 ICSS
2.1.1 ICSS
2.1.4 User Interface
2.1.4 User Interface  
2.1.5 Alarm Management  
2.1.5 Alarm Management  
2.1.5 Alarm Management  
2.1.5 Alarm Management

How can I loop through these strings & count the total of each type. e.g. The results would be:
2.1.1. ICSS = 3
2.1.4 User Interface = 2
2.1.5 Alarm management = 4

Thanks
Paul.

How are they delimited?

Regardless, use a HashTable type structure and add a counter variable to it using the strings as the key.  If the key already exists then increment the value already stored there.

What version C# are you using?

Idle_Mind,
                I am using Visual Web Developer 2005. I have never used hash tables before. Any help on these appreciated.

Thanks
Paul.

I don't do web development...but hopefully this should give a good idea of how it can be done:
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
 
        private StringBuilder sb = new StringBuilder();
 
        private void Form1_Load(object sender, EventArgs e)
        {
            sb.Append("2.1.1 ICSS" + ",");
            sb.Append("2.1.1 ICSS" + ",");
            sb.Append("2.1.1 ICSS" + ",");
            sb.Append("2.1.4 User Interface" + ",");
            sb.Append("2.1.4 User Interface" + ",");
            sb.Append("2.1.5 Alarm Management" + ",");
            sb.Append("2.1.5 Alarm Management" + ",");
            sb.Append("2.1.5 Alarm Management" + ",");
            sb.Append("2.1.5 Alarm Management");
        }
 
        private void button1_Click(object sender, EventArgs e)
        {
            Dictionary<string, int> counts = new Dictionary<string, int>();
            foreach (String value in sb.ToString().Split(",".ToCharArray()))
            {
                if (!counts.ContainsKey(value))
                {
                    counts.Add(value, 1);
                }
                else
                {
                    counts[value] = counts[value] + 1;
                }
            }
 
            foreach (String key in counts.Keys)
            {
                MessageBox.Show(key + " = " + counts[key].ToString());
            }
        }
 
    }
