示例1: Verify
/// <summary>
/// Computes the hash for the specified stream and compares
/// it to the value in this object. CRC hashes are not supported
/// because there is no built-in support in the .net framework and
/// a CRC implementation exceeds the scope of this project. If you
/// attempt to Verify() a CRC hash a NotImplemented() exception will
/// be thrown.
/// </summary>
/// <param name="istream">The stream to compute the hash for</param>
/// <returns>True if the computed hash matches what's stored in this object.</returns>
