	/// <summary>
	 /// 拆分文件
	 /// </summary>
	 static void Cut()
	 {
	 try
	 {
	 string path = @"C:\Users\zkk\Desktop\123.rar";
	 System.IO.FileStream fs = new System.IO.FileStream(path, System.IO.FileMode.Open, System.IO.FileAccess.Read, System.IO.FileShare.ReadWrite);
	 long len = fs.Length;
	 int temp = 1024 * 1024 * 2;
	 long shenxia = len;
	 byte[] bytes = new byte[temp];
	 string p1 = string.Empty;
	 int i = 0;
	 while (shenxia > 0)
	 {
	 p1 = @"D:\cut\";
	 i++;
	 if (!System.IO.Directory.Exists(p1)) System.IO.Directory.CreateDirectory(p1);
	 p1 = p1 + DateTime.Now.AddSeconds(i).AddTicks(100).ToString("yyyyMMddHHmss") + ".rar";
	 if (shenxia < temp)
	 temp = (int)shenxia;
	 fs.Read(bytes, 0, temp);

	 shenxia = shenxia - temp;

	 System.IO.FileStream f = new System.IO.FileStream(p1, System.IO.FileMode.Create, System.IO.FileAccess.Write);
	 f.Write(bytes, 0, temp);
	 f.Flush();
	 f.Close();

	
	 }
	 }
	 catch (Exception ex)
	 {
	 Console.WriteLine(ex.Message);
	 }
	 }

	 /// <summary>
	 /// 合并文件
	 /// </summary>
	 static void Meg()
	 {
	 string p = @"D:\cut\";
	 string pp=p+DateTime.Now.ToString("yyyyMMddHHmss") + ".rar";
	 string[] files = System.IO.Directory.GetFiles(p, "*.rar");
	 Array.Sort(files);

	 System.IO.FileStream fileStreamReader;
	 //追加流
	 System.IO.FileStream fileStreamWriter=new System.IO.FileStream(pp, System.IO.FileMode.Create, System.IO.FileAccess.Write);
	 foreach (string s in files)
	 {
	 fileStreamReader = new System.IO.FileStream(s, System.IO.FileMode.Open, System.IO.FileAccess.Read);
	 byte[] bytes = new byte[fileStreamReader.Length];
	 fileStreamReader.Read(bytes, 0, bytes.Length);
	 fileStreamReader.Close();

	 //byte数组追加
	 fileStreamWriter.Write(bytes, 0, bytes.Length);

	 }
	 fileStreamWriter.Flush();
	 fileStreamWriter.Close();
	

	 }

试试其它关键字

　拆分文件　　合并文件　　合并byte　

同语言下
