如何使用 [CallerMemberName], [CallerFilePath], 和 [CallerLineNumber]：写日志可能会用到

using System;
using System.Runtime.CompilerServices;

public class Logger
{
    public void Log(string message, 
                    [CallerMemberName] string memberName = "",
                    [CallerFilePath] string filePath = "",
                    [CallerLineNumber] int lineNumber = 0)
    {
        Console.WriteLine($"Message: {message}, Member: {memberName}, File: {filePath}, Line: {lineNumber}");
    }
}

public class Example
{
    private Logger logger = new Logger();

    public void TestMethod()
    {
        logger.Log("This is a test log.");
    }
}
 

class Program
{
    static void Main()
    {
        var example = new Example();
        example.TestMethod();
    }
}
输出：
Message: This is a test log., Member: TestMethod, File: /path/to/file.cs, Line: 25
