C#文件合并的方法

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();

希望本文所述对大家的c#程序设计有所帮助。
