I have a loop where i create some string value based on certain conditions. I did place StringBuilder object outside of the loop and each time i have new row in loop i need to clear StringBuilder appended values for this row. How do i clear those? StringBuilder sb = new StringBuilder(); foreach (DataRow row in recipientsList.Rows) { sb.Length = 0; sb.Append("<ul>"); if (row["needsToActivate"] == "1") { sb.AppendFormat("<li>{0}</li>", getUsersWithoutActivationTemplate()); } if (row["needsToEnterSite"] == "1") { sb.AppendFormat("<li>{0}</li>", getUsersWithoutEnteringWebsiteForTwoWeeksTemplate()); } if (row["needsPicture"] == "1") { sb.AppendFormat("<li>{0}</li>", getUsersWithoutPicturesTemplate()); } if (row["needsText"] == "1") { sb.AppendFormat("<li>{0}</li>", getUsersWithoutTextTemplate()); } if (row["needsCharacteristic"] == "1") { sb.AppendFormat("<li>{0}</li>", getUsersWithoutCharateristicsTemplate()); } if (row["needsHobby"] == "1") { sb.AppendFormat("<li>{0}</li>", getUsersWithoutHobbiesTemplate()); } sb.Append("</ul>"); } Code with accepted answer;
