how to covert integer value to double in listview subitems.

private void AddItems()
        {
            if (ListView1.Items.Count == 0)
            {
                ListViewItem lsv = new ListViewItem();
                cmbCategory.Enabled = true;
                cmbCategory.Enabled = true;
                lsv.SubItems.Add(txtItemCode.Text);
                lsv.SubItems.Add(txtProductName.Text);
                lsv.SubItems.Add(txtPrice.Text);
                lsv.SubItems.Add(txtAvailableQty.Text);
                lsv.SubItems.Add(textBox2.Text);
                lsv.SubItems.Add(txtTotalAmount.Text);
                lsv.SubItems.Add(cmbItem.SelectedValue.ToString());
                lsv.SubItems.Add(cmbCategory.Text);
                lsv.SubItems.Add(cmbItem.Text);
                ListView1.Items.Add(lsv);
                txtTotal.Text = subtot().ToString();

                return;
             }
public double subtot()
        {
            int i = 0;
            int j = 0;
            int k = 0;
            i = 0;
            j = 0;
            k = 0;
            try
            {
                j = ListView1.Items.Count;
                for (i = 0; i <= j - 1; i++)
                {
                    k = k + Convert.ToInt32(ListView1.Items[i].SubItems[6].Text);

                }
            }
}

This is my code. if the Subitems[6] value decimal means (that means total amount) i am getting input string is not valid error. how to i get even decimal value also

Try this:

public double subtot()
{
int i = 0;
int j = 0;
double k = 0;

try
{
j = ListView1.Items.Count;
for (i = 0; i <= j - 1; i++)
{
k = k + Convert.ToDouble(ListView1.Items[i].SubItems[6].Text);
}
}
catch(Exception ex)
{
MessageBox.Show(ex.Message);
return 0;
}

return k;
}
