使用 Log4Net 创建只读日志文件
我正在用 C# 开发应用程序，该应用程序创建 2 个日志文件（.txt 文件）：一个用于错误，另一个用于用户所做的修改。这两个文件是使用 log4net 创建的。我看到的问题是该文件可以被编辑，因此会被错误地更改。
我想将此文件设置为只读，并且 log4net 仍然可以对其进行写入。因为如果我只是更改文件中的属性，则不会写入下一个日志。
有办法做到这一点吗？
此外，应用程序的用户可以从应用程序内打开此日志文件。为此，我使用下一个代码：
System.IO.FileInfo finfo = new System.IO.FileInfo("path");
if (finfo.Exists)
{
//finfo.Attributes = System.IO.FileAttributes.ReadOnly;
// I don't use the previous line at the moment, because it blocks the followings logs.
System.Diagnostics.Process.Start("path");
}
这是创建和调用记录器的代码：
public static class CLogger
{
private static readonly ILog logger = LogManager.GetLogger(typeof(CLogger));
static CLogger()
{
XmlConfigurator.Configure(new System.IO.FileInfo("path to .config file"));
}
public static void WriteLog(ELogLevel logLevel, String log)
{
if (logLevel.Equals(ELogLevel.DEBUG))
{
logger.Debug(log);
}
else if (logLevel.Equals(ELogLevel.ERROR))
.
.
.
else if (logLevel.Equals(ELogLevel.WARN))
{
logger.Warn(log);
}
}
}
调用记录器：
CLogger.WriteLog(ELogLevel.ERROR, ex.ToString());
I'm developing application in c# that creates 2 log files (.txt files): one for errors and another for modifications made by users. This two files are created with log4net. The issue I see is that this files can be edited, and so altered by mistake.
I would like to set this files to readonly, and that log4net still could write on them. Because if I just change the property in the file, the next log wont be written.
There is a way to do that?
Also, the user of the app can open this logs file from within the app. For that I use the next code:
System.IO.FileInfo finfo = new System.IO.FileInfo("path");
if (finfo.Exists)
{
//finfo.Attributes = System.IO.FileAttributes.ReadOnly;
// I don't use the previous line at the moment, because it blocks the followings logs.
System.Diagnostics.Process.Start("path");
}
And this is the code to create and call the logger:
public static class CLogger
{
private static readonly ILog logger = LogManager.GetLogger(typeof(CLogger));
static CLogger()
{
XmlConfigurator.Configure(new System.IO.FileInfo("path to .config file"));
}
public static void WriteLog(ELogLevel logLevel, String log)
{
if (logLevel.Equals(ELogLevel.DEBUG))
{
logger.Debug(log);
}
else if (logLevel.Equals(ELogLevel.ERROR))
.
.
.
else if (logLevel.Equals(ELogLevel.WARN))
{
logger.Warn(log);
}
}
}
Calling to the logger:
CLogger.WriteLog(ELogLevel.ERROR, ex.ToString());

基本上，如果应用程序在用户的权限下运行，则用户最终必须有权访问这些文件：如果没有，应用程序也将无法写入该文件。
Basically, if the application runs under the rights of the user, than the user ultimately must have the rights to access the files: if he doesn't, the application wouldn't be able to write into this files either.
我会更改正在写入日志的文件夹的权限。 Web 服务器授予读/写权限，其他所有权限均为读权限。
I would change the rights on the folder where the logs are being written. The web server granted Read/Write, all other only Read.
