前言

我将简单的HandyControl的消息打印系统和Nlog搭配使用，简化我们的代码书写

.NET 控制台NLog 使用

WPF-UI HandyControl 控件简单实战

C#更改控制台文字输出颜色

Nlog配置

这里安装这个文章配置就行了，但是彩色控制台打印需要修改一下，Console.Colorful官网好像被占用了，只能用原生的方法改颜色了

.NET 控制台NLog 使用

C#更改控制台文字输出颜色

using NLog.Config;
using NLog;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace WpfApp1.Utils
{public static class NLogHelper{private static Logger logger;static NLogHelper(){LogManager.Configuration = new XmlLoggingConfiguration(string.Format("{0}/NLog.config", AppDomain.CurrentDomain.BaseDirectory.ToString()));logger = NLog.LogManager.GetCurrentClassLogger();}public static void Debug(string msg){Console.WriteLine(msg);logger.Debug(msg);}public static void Info(string msg){ConsoleWirte(msg,ConsoleColor.Green);logger.Info(msg);}public static void Error(string msg){ConsoleWirte(msg, ConsoleColor.Red);logger.Error(msg);}public static void Warning(string msg){ConsoleWirte(msg, ConsoleColor.Yellow);logger.Warn(msg);}public static void ConsoleWirte(string msg,ConsoleColor color){Console.ForegroundColor = color;Console.WriteLine(msg);Console.ResetColor();}}
}

HandyControl配置

修改了一下HandyControl的打印逻辑

using HandyControl.Controls;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;namespace WpfApp1.Utils
{public static class MsgHelper{public enum MsgType { Info, Warn, Error, Success, Fatal }/// <summary>/// 打印消息/// </summary>/// <param name="msg"></param>/// <param name="type"></param>/// <param name="isGlobal"></param>public static void ShowMsg(string msg, MsgType type, bool isGlobal = false){if (isGlobal){switch (type){case MsgType.Info:NLogHelper.Info(msg);Growl.InfoGlobal(msg);break;case MsgType.Warn:NLogHelper.Warning(msg);Growl.WarningGlobal(msg);break;case MsgType.Error:NLogHelper.Error(msg);Growl.ErrorGlobal(msg);break;case MsgType.Success:NLogHelper.Info(msg);Growl.SuccessGlobal(msg);break;case MsgType.Fatal:NLogHelper.Error(msg);Growl.FatalGlobal(msg);break;}}else{switch (type){case MsgType.Info:NLogHelper.Info(msg);Growl.Info(msg);break;case MsgType.Warn:NLogHelper.Warning(msg);Growl.Warning(msg);break;case MsgType.Error:NLogHelper.Error(msg);Growl.Error(msg);break;case MsgType.Success:NLogHelper.Info(msg);Growl.Success(msg);break;case MsgType.Fatal:NLogHelper.Error(msg);Growl.Fatal(msg);break;}}}/// <summary>/// 询问回调/// </summary>/// <param name="msg"></param>/// <param name="callback"></param>/// <param name="isGlobal"></param>public static void Ask(string msg, Action<bool> callback, bool isGlobal = false){NLogHelper.Info(msg);if (isGlobal){Growl.AskGlobal(msg, isConfrimed =>{callback(isConfrimed);return true;});}else{Growl.Ask(msg, isConfrimed =>{callback(isConfrimed);return true;});}}/// <summary>/// 强制清空全部消息/// </summary>public static void CleanAll(){Growl.Clear();Growl.ClearGlobal();}public static void Info(string msg){NLogHelper.Info(msg);Growl.Info(msg);}public static void Warning(string msg){NLogHelper.Warning(msg);Growl.Warning(msg);}public static void Error(string msg) {NLogHelper.Error(msg);Growl.Error(msg);}public static void Fatal(string msg) {NLogHelper.Error(msg);Growl.Fatal(msg);}public static void Success(string msg) {NLogHelper.Info(msg);Growl.Success(msg);}public static void InfoGlobal(string msg){NLogHelper.Info(msg);Growl.InfoGlobal(msg);}public static void WarningGlobal(string msg){NLogHelper.Warning(msg);Growl.WarningGlobal(msg);}public static void ErrorGlobal(string msg){NLogHelper.Error(msg);Growl.ErrorGlobal(msg);}public static void FatalGlobal(string msg){NLogHelper.Error(msg);Growl.FatalGlobal(msg);}public static void SuccessGlobal(string msg){NLogHelper.Info(msg);Growl.SuccessGlobal(msg);}}
}

文本内容

全局异常捕捉

博客园 WPF 捕捉全局异常

将里面弹窗代码改成我们的弹窗代码

using System.Configuration;
using System.Data;
using System.Text;
using System.Windows;
using System.Windows.Threading;
using WpfApp1.Utils;namespace WpfApp1
{/// <summary>/// Interaction logic for App.xaml/// </summary>public partial class App : Application{public App(){//首先注册开始和退出事件this.Startup += new StartupEventHandler(App_Startup);this.Exit += new ExitEventHandler(App_Exit);}void App_Startup(object sender, StartupEventArgs e){//UI线程未捕获异常处理事件this.DispatcherUnhandledException += new DispatcherUnhandledExceptionEventHandler(App_DispatcherUnhandledException);//Task线程内未捕获异常处理事件TaskScheduler.UnobservedTaskException += TaskScheduler_UnobservedTaskException;//非UI线程未捕获异常处理事件AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException);}void App_Exit(object sender, ExitEventArgs e){//程序退出时需要处理的业务}void App_DispatcherUnhandledException(object sender, System.Windows.Threading.DispatcherUnhandledExceptionEventArgs e){try{e.Handled = true; //把 Handled 属性设为true，表示此异常已处理，程序可以继续运行，不会强制退出      MsgHelper.Error("UI线程异常:" + e.Exception.Message);//MessageBox.Show("UI线程异常:" + e.Exception.Message);}catch (Exception ex){//此时程序出现严重异常，将强制结束退出//MessageBox.Show("UI线程发生致命错误！");MsgHelper.FatalGlobal("UI线程发生致命错误！"+ex.ToString());}}void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e){StringBuilder sbEx = new StringBuilder();if (e.IsTerminating){sbEx.Append("非UI线程发生致命错误");}sbEx.Append("非UI线程异常：");if (e.ExceptionObject is Exception){sbEx.Append(((Exception)e.ExceptionObject).Message);}else{sbEx.Append(e.ExceptionObject);}//MessageBox.Show(sbEx.ToString());MsgHelper.Error(sbEx.ToString());}void TaskScheduler_UnobservedTaskException(object sender, UnobservedTaskExceptionEventArgs e){//task线程内未处理捕获MsgHelper.Error("Task线程异常：" + e.Exception.Message);//MessageBox.Show("Task线程异常：" + e.Exception.Message);e.SetObserved();//设置该异常已察觉（这样处理后就不会引起程序崩溃）}}}

异常代码

        public RelayCommand ErrorNull { get; set; }public RelayCommand ErrorTask { get; set; }public RelayCommand ErrorReadNull { get; set; }public List<int> Errors { get; set; }
......ErrorNull = new RelayCommand(() =>{Errors.Add(0);});ErrorReadNull = new RelayCommand(() =>{var res = File.ReadAllLines("读取文件");});ErrorTask = new RelayCommand(() =>{Task.Run(() =>{Errors.Add(0);});});

运行结果

也可以进入断点

但是有时候不能进入Task异常，有点奇怪，如果是Task异常需要自己主动Try,catch。
