internet-connection

I have a C# code that basically uploads a file via FTP protocol (using FtpWebRequest). I'd like, however, to first determine whether there is a working internet connection before trying to upload the file (since, if there isn't there is no point in trying, the software should just sleep for a time and check again).

Is there an easy way to do it or should I just try to upload the file and in case it failed just try again, assuming the network connection was down?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
