Dynamic string formatting in c#

问题

I created log method that accept string. When I want to use it I write something like:

Log(string.Format("Message {0}", AdditionalInfo));

How should I implement Log method in order to be able to use string Format but do not have to write it explicitly in method arguments:

Log("Message {0}", AdditionalInfo);

I use .net 2.0

回答1:

public void Log(string formatString, params object[] parameters)
{
    Log(String.Format(formatString, parameters));
}

回答2:

public void Log(string format, params object[] args)
{
    DoTheLog(string.Format(format, args));
}

回答3:

void Log(string format, params object[] args)
{
  Log(string.Format(format, args));
}

回答4:

Try something like:

public void Log(string format, params object[] arguments)
{
    string message = string.Format(format, arguments);
    // Do something with message.
}

回答5:

You could perhaps write a wrapper for your Log method. I hope something like this works.

public void Log(string format, object args)
{
    Do_Log(string.Format(format, args))
}

Now you can have Do_Log() as private and not expose it to consumers of your class.
