The following examples contains code snippets that use methods and properties from:
Combine URLs:
// Example #1 - item URL string itemUrl = SPUrlUtility.CombineUrl(siteUrl, myList.DefaultViewUrl); // Example #2 - item properties URL string itemPropertiesUrl = SPUrlUtility.CombineUrl(siteUrl, myList.DefaultDisplayFormUrl) + "?id=" + myListItem.ID.ToString();
Obtain a query string parameter:
SPHttpUtility.UrlKeyValueDecode(Request.QueryString["MyParam"])
Redirect to a 'newUrl':
SPUtility.Redirect(newUrl, SPRedirectFlags.RelativeToLayoutsPage, HttpContext.Current);
Convert a DateTime value to ISO8601 DateTime format (yyyy-mm-ddThh:mm:ssZ):
string now = Microsoft.SharePoint.Utilities.SPUtility.CreateISO8601DateTimeFromSystemDateTime(DateTime.Now);
Send an email:
private void SendMail(SPWeb web, string from, string to, string subject, string body, bool isBodyHtml, string cc, string bcc) { try { StringDictionary headers = new StringDictionary(); headers.Add("from", from); headers.Add("to", to); headers.Add("subject", subject); if (!String.IsNullOrEmpty(cc)) headers.Add("cc", cc); if (!String.IsNullOrEmpty(bcc)) headers.Add("bcc", bcc); headers.Add("content-type", "text/html"); SPUtility.SendEmail(web, headers, body); } catch (Exception exc) { // ... log the exception } }
Send an email using SmtpClient instead of SPUtility.SendEmail:
public void SendMail1(SPWeb web, string from, string to, string subject, string body, bool isBodyHtml, string cc, string bcc) { try { SmtpClient client = new SmtpClient(); client.Host = web.Site.WebApplication.OutboundMailServiceInstance.Server.Address; MailMessage message = new MailMessage(from, to, subject, body); if (!String.IsNullOrEmpty(cc)) { MailAddress addressCC = new MailAddress(cc); message.CC.Add(addressCC); } if (!String.IsNullOrEmpty(bcc)) { MailAddress addressBcc = new MailAddress(bcc); message.Bcc.Add(addressBcc); } message.IsBodyHtml = isBodyHtml; client.Send(message); } catch (Exception exc) { // ... log the exception } }
Check if the protocol (http, https, etc.) is allowed:
if (SPUrlUtility.IsProtocolAllowed(url)) { // ... }
