【CSharp】 byte[]和文件FileStream相互转化

作者:xiaofengfeng / 发布于2014/5/26/ 499


	using System.IO;

	//读filename到byte[]

	 private byte[] ReadFile(string fileName)

	 {

	 FileStream pFileStream = null;

	 byte[] pReadByte = new byte[0];

	 try

	 {

	 pFileStream = new FileStream(fileName, FileMode.Open, FileAccess.Read);

	 BinaryReader r = new BinaryReader(pFileStream);

	 r.BaseStream.Seek(0, SeekOrigin.Begin); //将文件指针设置到文件开

	 pReadByte = r.ReadBytes((int)r.BaseStream.Length);

	 return pReadByte;

	 }

	 catch

	 {

	 return pReadByte;

	 }

	 finally

	 {

	 if (pFileStream != null)

	 pFileStream.Close();

	 }

	 }

	 //写byte[]到fileName

	 private bool writeFile(byte[] pReadByte, string fileName)

	 {

	 FileStream pFileStream = null;

	 try

	 {

	 pFileStream = new FileStream(fileName, FileMode.OpenOrCreate);

	 pFileStream.Write(pReadByte, 0, pReadByte.Length);

	

	 }

	 catch

	 {

	 return false;

	 }

	 finally

	 {

	 if (pFileStream != null)

	 pFileStream.Close();

	 }

	 return true;

	 }

	 测试

	 private void button6_Click(object sender, EventArgs e)

	 {

	 //by 闫磊 Email:Landgis@126.com,yanleigis@21cn.com 2007.11.23

	byte[] b = ReadFile(@"c:\u.jpg");

	 if (writeFile(b, @"c:\u1.jpg"))

	 {

	 MessageBox.Show("成功");

	 }

	 else { MessageBox.Show("失败"); }

	 }

试试其它关键字

　FileStream　

同语言下

可能有用的
