在catch或c#中每个方法的内部调用日志方法的位置

实际上，我想以这样一种方式记录数据，它应该具有应用程序在c#中经历的方法，如果有错误，那么错误内容也应该被记录。问题是在哪里调用日志方法的catch内部或内部的每个方法?因为我有将近200个方法。

我写的代码是这样的:

    public static bool Logging(System.Reflection.MethodBase methodInfo)
     {
        var fullMethodName = methodInfo.DeclaringType.FullName + "." + methodInfo.Name;
        if (error_flag == false)
        {
            using (StreamWriter outputFile = new StreamWriter(path + @"'log.txt", true))
            {
                outputFile.WriteLine(fullMethodName + ": OK");
            }
        }
        else
        {
            using (StreamWriter outputFile = new StreamWriter(path + @"'log.txt", true))
            {
                outputFile.WriteLine("'n'n --> Error in : " + fullMethodName);
            }
        }
        return true;
    }
    //Logging Method 2
    public static bool WriteErrorLog(Exception ErrorMessage)
    {
        using (StreamWriter outputFile = new StreamWriter(path + @"'log.txt", true))
        {
            outputFile.WriteLine("{0} Exception caught.", ErrorMessage);
        }
        return true;
    }

，我必须从哪里调用这些方法??

static void Main()
{
    try
    {
        Log.Info("Start of process");
        string input = StepOne();
        StepTwo(input);
        Log.Info("End of process");
    }
    catch(Exception e)
    {
        Log.Error(e);
    }
}
public static string StepOne()
{
    Log.Info("StepOne Completed");
    return "Step One";
}
public static void StepTwo(string input)
{
    Log.Info("StepTwo, input: " + input);
    throw new ArgumentNullException("input");
}
