This is a code snippet showing how you may call the “mailto” to open your mail program.
private void SendEmail(string email, string subject, string body)
{
Uri uri = new Uri(String.Format("mailto:{0}?subject={1}&body={2}", email, subject, body));
System.Windows.Browser.HtmlPage.Window.Navigate(uri);
}
The code helps to you navigate to an external link or website using code and HyperlinkButton. Please not that if you are running the application in out of browser mode, the C# will not work . In such case, you have to use HyperlinkButton to open an external link.
using System.Windows.Browser;
private void Button_Click(object sender, RoutedEventArgs e)
{
Uri uri = new Uri("http://silverlike.net", UriKind.Absolute);
HtmlPage.PopupWindow(uri, "_blank", new HtmlPopupWindowOptions() { Width = 800, Height = 600};
// or
HtmlPage.Window.Navigate(uri, "_blank");
}
<HyperlinkButton Content="Silverlike" NavigateUri="http://silverlike.net" TargetName="_blank"/>
Integrate with the browser cookie for saving and accessing data in the cookie.
// sample usage
CookieManager.SetCookie("key", "value", TimeSpan.FromSeconds(3600));
string value = CookieManager.GetCookie("value");
// cookie manager class
public class CookieManager
{
public static void SetCookie(string key, string val, TimeSpan? expires)
{
SetCookie(key, val, expires, null, null, false);
}
public static void SetCookie(string key, string val, TimeSpan? expires, string path, string domain, bool secure)
{
StringBuilder fullCookie = new StringBuilder();
fullCookie.Append(string.Concat(key, "=", val));
if (expires.HasValue)
{
DateTime expire = DateTime.UtcNow + expires.Value;
fullCookie.Append(string.Concat(";expires=", expire.ToString("R")));
}
if (path != null)
{
fullCookie.Append(string.Concat(";path=", path));
}
if (domain != null)
{
fullCookie.Append(string.Concat(";domain=", domain));
}
if (secure)
{
fullCookie.Append(";secure");
}
HtmlPage.Document.SetProperty("cookie", fullCookie.ToString());
}
public static string GetCookie(String key)
{
String[] cookies = HtmlPage.Document.Cookies.Split(';');
String result = (from c in cookies let keyValues = c.Split('=') where
keyValues.Length == 2 && keyValues[0].Trim() == key.Trim()
select keyValues[1]).FirstOrDefault();
return result;
}
public static void DeleteCookie(String key){
DateTime expir =DateTime.UtcNow -TimeSpan.FromDays(1);
string cookie =String.Format("{0}=;expires={1}",
key, expir.ToString("R"));
HtmlPage.Document.SetProperty("cookie", cookie);
}
public static bool Exists(String key, String value)
{
return HtmlPage.Document.Cookies.Contains(String.Format("{0}={1}", key, value));
}
}
