java - Reading data from a server and detecting network unavailability in C# -

I have a simple task: to read data from a server, if the server is unrecoverable (server down or bad network) Load data (potentially stale) from local disk cache.

How Java code looks like this is a simple pseudo representation:

  try {// read from server //} (iOException ioe) {// Most likely That socket timeout read from the local disk exception} {{free I / O resource}}   
 but implementing it does not appear in C # It seems that the  WebClient , whenever there is no internet access on the host machine, then through the catch block, that situation So there is no way out and back into the local cache. I am aware of the async API of the  WebClient  and instead the fun callback series, but I consider it very strange and do not properly adhere to my design goals. Is there any way that I can do this in C # as easily as the Java Skeleton Code shown above? Thank you.   
 
 
 WebClient will be timeout, but only after 100  
 I would recommend that instead you use HttpWebRequest it has a fixed timeout asset.
