C#文件相关的操作

static string ReadAllText(string log_file) //读取文件

{

FileStream fs = null;

StreamReader sr = null;

try

{

fs = new FileStream(log_file, FileMode.Open, FileAccess.Read, FileShare.ReadWrite);

sr = new StreamReader(fs, Encoding.UTF8);

return sr.ReadToEnd();

}

catch (Exception)

{

Console.Error.WriteLine(“Can’t read log {0}”, Path.GetFileName(log_file));

}

finally

{

if (sr != null) sr.Close();

if (fs != null) fs.Close();

}

return “”;

}

写文件也可用：

File.AppendAllText(“D:\Hexu\TestLog.txt”, sLogFilePath[0] + “\r\n”);

当然也可以用WriteStream的方法
