本文实例讲述了C#文件合并的方法。分享给大家供大家参考。具体实现方法如下：

using System;

using System.IO;

string filetomerge=@"C:/temp/data.bin";

string targetpath=@"D:/store";

string strFileName = filetomerge.Substring(filetomerge.LastIndexOf(Path.DirectorySeparatorChar) + 1);

FileStream fsr1 = new FileStream(targetpath+ Path.DirectorySeparatorChar + strFileName + "1", FileMode.Open, FileAccess.Read);

FileStream fsr2 = new FileStream(targetpath+ Path.DirectorySeparatorChar + strFileName + "2", FileMode.Open, FileAccess.Read);

byte[] btArr = new byte[fsr1.Length+fsr2.Length];

fsr1.Read(btArr, 0, Convert.ToInt32(fsr1.Length));

fsr2.Read(btArr, Convert.ToInt32(fsr1.Length), Convert.ToInt32(fsr2.Length));

fsr1.Close();

fsr2.Close();

FileStream fsw = new FileStream(%%2 + Path.DirectorySeparatorChar+ strFileName, FileMode.Create, FileAccess.Write);

fsw.Write(btArr, 0, btArr.Length);

fsw.Flush();

fsw.Close();
