C# 控制台彩色深度打印 工具类

前言

有时候我们想要靠打印获得程序信息，因为Dubeg模式需要一点一点断点进入进出，但是我们觉得断点运行实在是太慢了，还是直接打印后找结果会好一点。

Nuget 环境安装

想自己写的话可以看我之前的文章

C# 控制台彩色打印

代码

新建一个Utils，里面放一个LogHelper

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Console = Colorful.Console;
namespace PubSubTest.Utils
{
    public static class LogHelper
    {
        /// 

        /// 打印等级
        /// 
        public static int PrintLevel = 0;

        /// 

        /// 堆栈追踪
        /// 
        /// 追踪深度,0为打印当前，1为打印上一层
        /// 
        private static string TraceMethodInfo(int deep)
        {
            //Color.Brown
            deep += 2;
            string info = "";
            try
            {
                StackFrame st = new System.Diagnostics.StackTrace(deep, true).GetFrame(0);
                info = $"{st.GetMethod().DeclaringType.FullName} :{st.GetFileLineNumber()}";
            }
            catch (Exception e)
            {
                Console.WriteLine(e.Message);
            }
            //Color.Brown;
            return info;
        }

        /// 

        /// 彩色深度打印
        /// 
        /// 信息
        /// 深度
        /// 等级
        public static void Log(string msg, int deep = 0, LogLevel state = LogLevel.Debug)
        {
            if ((int)state >= PrintLevel)
            {
                
                ColorPrint($"{state.ToString()}\t" +msg, (int)state);
                var deepMsg = TraceMethodInfo(deep);
                Console.WriteLine("\t" + deepMsg, (int)state);
            }
        }



        private static void ColorPrint(string msg, int state)
        {
            switch (state)
            {
                case 0:
                    Console.WriteLine(msg);
                    break;
                case 1:
                    Console.WriteLine(msg, Color.LightGreen);
                    break;
                case 2:
                    Console.WriteLine(msg, Color.Yellow);
                    break;
                case 3:
                    Console.WriteLine(msg, Color.Red);
                    break;
                case 4:
                    Console.WriteLine(msg, Color.LightPink);
                    break;
            }

        }



    }

    /// 

    /// 日志等级
    /// 
    public enum LogLevel : int
    {
        Debug = 0,
        Info = 1,
        Warn = 2,
        Error = 3,
        Must = 4
    }
}

Tips:using Console = Colorful.Console;这句话别忘记了

使用

    internal class Program
    {
        public static Action action;

        public static PubSubHelper helper = new PubSubHelper();
        static void Main(string[] args)
        {
            Test();
            //Console.WriteLine(LogLevel.Warn.ToString());
            Console.ReadLine();
        }


        public static void Test()
        {
            LogHelper.Log("打印测试",0);
            LogHelper.Log("打印测试",1);
            LogHelper.Log("打印测试",1,LogLevel.Debug);
            LogHelper.Log("打印测试",1,LogLevel.Info);
            LogHelper.Log("打印测试",1,LogLevel.Warn);
            LogHelper.Log("打印测试",1,LogLevel.Error);
            LogHelper.Log("打印测试",1,LogLevel.Must);

        }
    }

打印结果

总结

大家可以根据深度和色彩自己自定义工具输出。
