Binding DatagridView with HashTable

If you have your data into an HashTable, and you wanna bind a DataGrdiView, look at the following code as example.

private void BindYourDataGridView()
            // here put data into the HashTable, but you can already have data
            // in you hashtable, in this case delete this lines -----------
            Hashtable YourData= new Hashtable();

            for (int i = 0; i < something; i++)
                YouData.Add(i, something[i]);
            DataSet ds = new DataSet();
            DataTable dt = ds.Tables.Add("data");

            dt.Columns.Add("A", typeof(string));

            IDictionaryEnumerator enumerator = YourData.GetEnumerator();

            DataRow row = null;
            //adding row in the datatable
            while (enumerator.MoveNext())
                int index = (int)enumerator.Key;
                string value = (string)enumerator.Value;
                row = dt.NewRow();
                row["A"] = index;
                row["B"] = value;

      Your_DataGridView.DataSource = ds.Tables[0];

My Two Cents ...
