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{/// <summary>/// 打印等级/// </summary>public static int PrintLevel = 0;/// <summary>/// 堆栈追踪/// </summary>/// <param name="deep">追踪深度,0为打印当前，1为打印上一层</param>/// <returns></returns>private static string TraceMethodInfo(int deep){//Color.Browndeep += 2;string info = "";try{StackFrame st = new System.Diagnostics.StackTrace(deep, true).GetFrame(0);info = $"{st.GetMethod().DeclaringType.FullName} :{st.GetFileLineNumber()}";}catch (Exception e){Console.WriteLine(e.Message);}//Color.Brown;return info;}/// <summary>/// 彩色深度打印/// </summary>/// <param name="msg">信息</param>/// <param name="deep">深度</param>/// <param name="state">等级</param>public static void Log(string msg, int deep = 0, LogLevel state = LogLevel.Debug){if ((int)state >= PrintLevel){ColorPrint($"{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;}}}/// <summary>/// 日志等级/// </summary>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。
