读写文件的问题！！！！！
本帖最后由 XiAnTianYiChuanMei 于 2013-09-11 19:17:54 编辑 FileStream fs = new FileStream(paht+@"\index.aspx", FileMode.Open, FileAccess.ReadWrite, FileShare.ReadWrite);
StreamReader sr = new StreamReader(fs);
string mb= sr.ReadToEnd();
mb = mb.Replace("$$$$$$$$$$$$$", textBox2.Text);
StreamWriter sTmp = new StreamWriter(fs);
sTmp.WriteLine(mb);
fs.Close();




这样的话，文件没有修改

FileStream fs = new FileStream(paht+@"\index.aspx", FileMode.Open, FileAccess.ReadWrite, FileShare.ReadWrite);
StreamReader sr = new StreamReader(fs);
string mb= sr.ReadToEnd();
mb = mb.Replace("$$$$$$$$$$$$$", textBox2.Text);
StreamWriter sTmp = new StreamWriter(paht + @"\index.aspx", false, Encoding.UTF8);
sTmp.WriteLine(mb);
fs.Close();
这样的话，又报错
文件“paht+@"\index.aspx"正由另一进程使用,因此该进程无法访问此文件。


怎么做，，不会了
[解决办法]

FileStream fs = new FileStream(@"test.txt", FileMode.Open, FileAccess.ReadWrite, FileShare.ReadWrite); 
 
            StreamReader sr = new StreamReader(fs);
            string mb = sr.ReadToEnd();
            mb = mb.Replace("$$$$$$$$$$$$$", "hello....");
            sr.Close();
            fs.Close();

            FileStream fs1 = new FileStream(@"test.txt", FileMode.Open, FileAccess.ReadWrite, FileShare.ReadWrite);
            StreamWriter sTmp = new StreamWriter(fs1);
            sTmp.WriteLine(mb);
            sTmp.Close();
            fs.Close();
