Use this single line of code:

int selectedCount = chkselectedItems.Items.Cast<ListItem>().Count(li => li.Selected);

Edit

int numSelected = 0;
foreach (ListItem li in chkselectedItems.Items)
{
if (li.Selected)
{
numSelected = numSelected + 1;
}
}
Response.Write("Total Number Of CheckBoxes Selected:");
Response.Write(numSelected);

pre

public string[] CheckboxListSelections(System.Web.UI.WebControls.CheckBoxList list)
{
 ArrayList values = new ArrayList();
 for(int counter = 0; counter < list.Items.Count; counter++)
 {
  if(list.Items[counter].Selected)
  {
   values.Add(list.Items[counter].Value);
  }    
 }
 return (String[]) values.ToArray( typeof( string ) );
}

We will iterate through the checkboxlist and use a counter variable for counting selected items. For every item in checkboxlist we will add 1 to counter variable selCount if item is checked

int selCount = 0;   

for(int i= 0; i< chklst.Items.Count; i++) 
  if(chklst.Items[i].Selected)
      selCount++;

// Now selCount will contain the count of selected items
