Speed up File.Exists for non existing network shares

Question

I have to check if a set of file paths represent an existing file.

It works fine except when the path contains a network share on a machine that\'s not on the curren

Answer 1

Another "thread solution":

/// Check if file exists with timeout
/// source
/// The number of milliseconds to wait,
///  or  (-1) to wait indefinitely.
/// Gets a value indicating whether a file exists.
public static bool Exists(this FileInfo fileInfo, int millisecondsTimeout)
{
    var task = new Task(() => fileInfo.Exists);
    task.Start();
    return task.Wait(millisecondsTimeout) && task.Result;
}

There are some concerns about "drive not responding fast enough", so this is compromise between speed and "the truth". Don't you use It if you want to be sure 100%.
