示例1: ForceDisposeStreamReader
/// <summary>
/// In some scenarios, a StreamReader will be blocked on read() when trying to dispose it.
/// On OS X under mono, read() will block any close() syscalls on the file descriptor for the stream.
/// Therefore, we write a byte to unblock the read() and allow close() to succeed.
/// Callers to this function should document why read() might be blocked.
/// </summary>
/// <param name="reader">The StreamReader to forcibly dispose</param>
protected static void ForceDisposeStreamReader(StreamReader reader)
{
try
