示例1: IsFormatSupported
/// <summary>
/// Determines if the specified output format is supported in shared mode
/// </summary>
/// <param name="shareMode">Share Mode</param>
/// <param name="desiredFormat">Desired Format</param>
/// <param name="closestMatchFormat">Output The closest match format.</param>
/// <returns>True if the format is supported</returns>

return shareMode != AudioClientShareMode.Exclusive;
}
Marshal.ThrowExceptionForHR(hresult);
// shouldn't get here
throw new NotSupportedException("Unknown hresult " + hresult);
