C# Help With IF Value = 0 Do Something

Now I know the Title sounds like I should know the answer. But here is my problem and I dont know how to code it

I am fetching an xml response, Most of the time DS.Tables["Price"] is returned in the response. But if its not returned my update fails.

DS.Tables["Price"] is only actually returned if the value = 1 in DS.Tables["Offers"]

if the value = 0  my script crashes.

please can someone explain / show me how I can change my code below to check for it and put an else statement in if the value  = 0

for (int i = 0; i < DS.Tables["Price"].Rows.Count; i++)
              string s6 = DS.Tables["Price"].Rows[i]["FormattedPrice"].ToString().Replace("£", "").Replace(",", "");
              string s7 = "1";// DS.Tables["Price"].Rows[i]["OfferListing_Id"].ToString();
              string n70 = (s11); 
              string sqld = string.Format("update dbo.price set Price ='"+ s6 +"' where productid='" + n70 +"'");

              SqlConnection con = new SqlConnection();
              con.ConnectionString = "Data Source=xxx;Initial Catalog=xxx;User Id=xxx; Password=xxx";
              SqlCommand cmd = new SqlCommand();
              cmd.Connection = con;
              cmd.CommandText = sqld;
