用FileStream 读取文件流并显示给文件内容
string p = @"C:\Users\Administrator\Desktop\1.txt"; FileStream fsR = new FileStream(p, FileMode.Open, FileAccess.Read);
byte[] buff = new byte[2];//设置内存缓存区大小
while (true)
{
int r= fsR.Read(buff, 0, buff.Length);
if (r == 0)
break;
else
{
string str= System.Text.Encoding.Default.GetString(buff);
Console.Write(str );
}
fsR.Close();//关闭流 fsR.Dispose();//释放资源
//FileStream 读写文件流
string p = @"C:\Users\Administrator\Desktop\2.mp4"; using (FileStream fsR = new FileStream(p2, FileMode.Open, FileAccess.Read))
{
using (FileStream fsW = new FileStream(p, FileMode.OpenOrCreate, FileAccess.Write))
{
byte[] buff = new byte[1024 * 1024 * 5];//设置缓存区大小为5MB
while (true)
{
int r = fsR.Read(buff, 0, buff.Length);//读取
if (r == 0)
break;
else
{
fsW.Write(buff, 0, r);//写入
}
}
}
}
