雅蠛蝶，救命啊。。。ICSharpCode问题，路径访问被拒绝啊

private string CreateZIPFile(string path, int M)

            System.IO.FileStream fs = System.IO.File.OpenRead(path + "\\" + DateTime.Now.ToString("yyyyMMddHH"));
            long pai = 1024 * 1024 * M;//每M兆写一次
            long forint = fs.Length / pai + 1;
            byte[] buffer = null;
            ZipEntry entry = new ZipEntry(System.IO.Path.GetFileName(path + "\\" + DateTime.Now.ToString("yyyyMMddHH")));
            entry.Size = fs.Length;
            entry.DateTime = DateTime.Now;
            zipout.PutNextEntry(entry);
            for (long i = 1; i <= forint; i++)
            {
                if (pai * i < fs.Length)
                {
                    buffer = new byte[pai];
                    fs.Seek(pai * (i - 1), System.IO.SeekOrigin.Begin);
                }
                else
                {

                    {
                        buffer = new byte[fs.Length - pai * (i - 1)];
                        fs.Seek(pai * (i - 1), System.IO.SeekOrigin.Begin);
                    }
                }
                fs.Read(buffer, 0, buffer.Length);
                crc.Reset();
                crc.Update(buffer);
                zipout.Write(buffer, 0, buffer.Length);
                zipout.Flush();
            }
            fs.Close();
            zipout.Finish();
            zipout.Close();
            System.IO.File.Delete(path);

        {
            string str = ex.Message;
            return null;
        }
    }

path到底是写文件路径，还是目录啊？目录跟我说访问拒绝，文件路径跟我说文件被另一个进程用着。压缩 ICSharpCode --------------------编程问答-------------------- 打开文件目录啊    --------------------编程问答--------------------
