Using the code below, I get this error.

Using the generic type 'System.Collections.Generic.IComparer<T>' requires
'1' type arguments

Please tell me how to put this right.

// Implements the manual sorting of items by columns.

   class ListViewItemComparer : IComparer
   {
       private int col;
       public ListViewItemComparer()
       {
           col = 0;

       public ListViewItemComparer(int column)
       {
           col = column;
       }
       public int Compare(object x, object y)
       {
           return String.Compare(((ListViewItem)x).SubItems[col].Text,
((ListViewItem)y).SubItems[col].Text);

 // ColumnClick event handler.
       private void ColumnClick(object o, ColumnClickEventArgs e)
       {
           // Set the ListViewItemSorter property to a new
ListViewItemComparer object.
           this.listView1.ListViewItemSorter = new

           // Call the sort method to manually sort the column based on the
ListViewItemComparer implementation.
           listView1.Sort();
