Remarks

The SmtpPermission and SmtpPermissionAttribute classes control access to SMTP host computers. The SmtpClient class demands an SmtpPermission when sending electronic mail to the SMTP host for delivery.

The SmtpAccess enumeration specifies the level of access controlled by an instance of this permission.

Example

The following code example creates an instance of an SmtpPermission.

C++

Copy

public static SmtpPermission CreateConnectPermission()
{
    SmtpPermission connectAccess = new 
        SmtpPermission(SmtpAccess.Connect);
    Console.WriteLine("Access? {0}", connectAccess.Access);
    return connectAccess;
}

Copy

public static SmtpPermission CreateConnectPermission()
{
    SmtpPermission connectAccess = new SmtpPermission(SmtpAccess.Connect);
    Console.WriteLine("Access? {0}", connectAccess.get_Access());
    return connectAccess;
} //CreateConnectPermission
