推荐答案

您可以使用的 Assembly.GetManifestResourceStream 获得流读取你的资源。然后，只需将它复制到的FileStream 。如果您使用.NET 4中，你可以使用 Stream.CopyTo 做出这么简单：

You can use Assembly.GetManifestResourceStream to get a stream to read your resource from. Then just copy it to a FileStream. If you're using .NET 4, you could use Stream.CopyTo to make that easy:

private void CopyResource(string resourceName, string file)
{
    using (Stream resource = GetType().Assembly
                                      .GetManifestResourceStream(resourceName))
    {
        if (resource == null)
        {
            throw new ArgumentException("No such resource", "resourceName");
        }
        using (Stream output = File.OpenWrite(file))
        {
            resource.CopyTo(output);
        }
    }
}
