windows 文件清理工具
标签：错误 sha build close pen ring 实现 线程 清理工具
磁盘不够大，备份文件每天都生成，大概半个月就得手工清理一次，基于此，花了点时间写了个简单文件清理工具
采用WinForm 4.6.1实现，页面上需要拖放一个TextBox 控件
1、配置文件：
2、全局错误处理
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace FileClearTools
{
static class Program
{
///
/// 应用程序的主入口点。
///
[STAThread]
static void Main()
{
try
{
//处理UI线程异常
Application.ThreadException += new System.Threading.ThreadExceptionEventHandler(Application_ThreadException);
//处理非UI线程异常
AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException);
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new FileClear());
}
catch (Exception ex)
{
string str = GetExceptionMsg(ex, string.Empty);
MessageBox.Show(str, "系统错误", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
static void Application_ThreadException(object sender, System.Threading.ThreadExceptionEventArgs e)
{
string str = GetExceptionMsg(e.Exception, e.ToString());
MessageBox.Show(str, "系统错误", MessageBoxButtons.OK, MessageBoxIcon.Error);
//LogManager.WriteLog(str);
}
static void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)
{
string str = GetExceptionMsg(e.ExceptionObject as Exception, e.ToString());
MessageBox.Show(str, "系统错误", MessageBoxButtons.OK, MessageBoxIcon.Error);
//LogManager.WriteLog(str);
}
///
/// 生成自定义异常消息
///
/// 异常对象
/// 备用异常消息：当ex为null时有效
/// 异常字符串文本
static string GetExceptionMsg(Exception ex, string backStr)
{
StringBuilder sb = new StringBuilder();
sb.AppendLine("****************************异常文本****************************");
sb.AppendLine("【出现时间】：" + DateTime.Now.ToString());
if (ex != null)
{
sb.AppendLine("【异常类型】：" + ex.GetType().Name);
sb.AppendLine("【异常信息】：" + ex.Message);
sb.AppendLine("【堆栈调用】：" + ex.StackTrace);
}
else
{
sb.AppendLine("【未处理异常】：" + backStr);
}
sb.AppendLine("***************************************************************");
return sb.ToString();
}
}
}
