推荐答案

使用自制的记录方法，您将面临许多问题。不要这样做。



我已经回答了你的其他问题，所以请使用我的建议：我可以用这段代码知道文件存储在哪里？并且日志代码是否可行？ [ ^ ]。

-SA

With your home-baked logging approach, you will face many problems. Don't do it.

I already answered you other question, so please use my advice: May I know with this code where will the files be stored to? and is the logging code workable?[^].

—SA

这是可能的。

您必须创建对象并在该对象上调用该方法，如下所示：



LogObject o = new LogObject（）;

o.log（这是我的信息）;



或



var myMessage =这是我的信息;

o.log（myMessage）;



第二个选项是让方法保持静态



而且你可以像这样调用它：

LogObject .log（这是我的信息）;



这是你想知道的吗？或者您正在寻找完全不同的东西？



评论后更新：



如果我说对了你试图把异常写入日志文件。

试试这个：



试试

{

//你的代码

}

catch（例外e）

{

LogObject .log（e.Message）;

}



这就是你需要的吗？

It is possible.
You have to create object and call that method on that object like this:

LogObject o = new LogObject();
o.log("This is my message");

or

var myMessage = "This is my message";
o.log(myMessage);

Second option is make the method static

And than you can call it like this:
LogObject.log("This is my message");

Is this what you wanted to know? or are you looking for something completely different?

Updated after comment:

If I get it right you are trying to write exception into a log file.
try this:

try
{
//your code
}
catch(Exception e)
{
LogObject.log(e.Message);
}

Is this what you need?
