一个简易的C#信息展示板
本文中的展示板是用TextBox实现的，因为工作需要，我实现了一个向TextBox自动生成格式化信息的工具类DisplayBoardHelper
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace DisplayBoard
{
public class DisplayBoardHelper
{
/// <summary>
/// 事件等级
/// </summary>
public enum LogLevel
{
/// <summary>
/// 调试
/// </summary>
DEBUG = 0,
/// <summary>
/// 信息
/// </summary>
INFO = 1,
/// <summary>
/// 通知
/// </summary>
NOTICE = 2,
/// <summary>
/// 警告
/// </summary>
WARNING = 3,
/// <summary>
/// 错误
/// </summary>
ERROR = 4,
/// <summary>
/// 严重
/// </summary>
CRIT = 5,
/// <summary>
/// 危险
/// </summary>
ALERT = 6,
/// <summary>
/// 紧急
/// </summary>
EMERG = 7
}
/// <summary>
/// 将报警等级的枚举打印成字符串
/// </summary>
/// <param name="level">事件等级</param>
/// <param name="lang">输出字符串语言 CHS：简体中文 ENG：英语</param>
/// <returns></returns>
private static string LevelToString(LogLevel level, string lang = "CHS")
{
if (lang == "CHS")
{
switch (level)
{
case LogLevel.DEBUG: return "调试";
case LogLevel.INFO: return "信息";
case LogLevel.NOTICE: return "通知";
case LogLevel.WARNING: return "警告";
case LogLevel.ERROR: return "错误";
case LogLevel.CRIT: return "严重";
case LogLevel.ALERT: return "危险";
case LogLevel.EMERG: return "紧急";
default: return "未知";
}
}
else if (lang == "ENG")
{
switch (level)
{
case LogLevel.DEBUG: return "DEBUG";
case LogLevel.INFO: return "INFO";
case LogLevel.NOTICE: return "NOTICE";
case LogLevel.WARNING: return "WARNING";
case LogLevel.ERROR: return "ERROR";
case LogLevel.CRIT: return "CRIT";
case LogLevel.ALERT: return "ALERT";
case LogLevel.EMERG: return "EMERG";
default: return "UNKNOWN";
}
}
else
{
throw new Exception(lang + "：未知语言类型");
}
}
/// <summary>
/// 向指定的TextBox中添加一条新日志
/// </summary>
/// <param name="tb">TextBox对象</param>

public static void AddLog(System.Windows.Forms.TextBox tb,
LogLevel logLevel, string logInfo, string lang = "CHS")
{
string sNewLog = string.Format("[{0}][{1}]:{2}\r\n",
DateTime.Now.ToLongTimeString(),
LevelToString(logLevel, lang),
logInfo);
tb.Text += sNewLog;
tb.Select(tb.TextLength, 0);
tb.ScrollToCaret();
}
/// <summary>
/// 查看TextBox的设置是否符合库最佳使用环境（这个函数并不是必须的，可以选择性调用）
/// </summary>
/// <param name="tb">TextBox对象</param>
/// <param name="suggestion">建议（返回false时可查看）</param>
/// <returns>true:合理 false:不合理</returns>
public static bool IsConfigReasonable(
System.Windows.Forms.TextBox tb,
out string suggestion)
{
bool isConfigReasonable = true;
suggestion = "建议：\n";
//TextBox应被设置为支持多行
if (tb.Multiline == false)
{
suggestion += "控件" + tb.Name + "只支持单行文本（Multiline）\n";
isConfigReasonable = false;
}
//TextBox应被设置为支持纵向滚动条
if (tb.ScrollBars != System.Windows.Forms.ScrollBars.Vertical ||
tb.ScrollBars != System.Windows.Forms.ScrollBars.Both)
{
suggestion += "控件" + tb.Name + "缺少纵向滚动条（ScrollBars）\n";
isConfigReasonable = false;
}
//ReadOnly属性和Enable属性应至少设置一个确保TextBox只读
if (tb.ReadOnly == false && tb.Enabled == true)
{
suggestion += "控件" + tb.Name + "可任意修改（ReadOnly or Enabled）\n";
isConfigReasonable = false;
}
//没有问题，不需要建议
if (isConfigReasonable)
{
suggestion = "";
}
return isConfigReasonable;
}
}
}
下面是这个示例程序的实现，这个示例程序中只有一个Dock属性被设置为Fill的TextBox
程序代码：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace DisplayBoard
{
public partial class FormMain : Form
{
public FormMain()
{
InitializeComponent();
}
private void FormMain_Load(object sender, EventArgs e)
{
//写入一些日志
DisplayBoardHelper.AddLog(this.txtDisplayBoard,
DisplayBoardHelper.LogLevel.DEBUG, "这是一条测试信息");
DisplayBoardHelper.AddLog(this.txtDisplayBoard,
DisplayBoardHelper.LogLevel.INFO, "这是一条测试信息");
DisplayBoardHelper.AddLog(this.txtDisplayBoard,
DisplayBoardHelper.LogLevel.NOTICE, "这是一条测试信息");
DisplayBoardHelper.AddLog(this.txtDisplayBoard,
DisplayBoardHelper.LogLevel.WARNING, "这是一条测试信息");
DisplayBoardHelper.AddLog(this.txtDisplayBoard,
DisplayBoardHelper.LogLevel.ERROR, "这是一条测试信息");
DisplayBoardHelper.AddLog(this.txtDisplayBoard,
DisplayBoardHelper.LogLevel.CRIT, "这是一条测试信息");
DisplayBoardHelper.AddLog(this.txtDisplayBoard,
DisplayBoardHelper.LogLevel.ALERT, "这是一条测试信息");
DisplayBoardHelper.AddLog(this.txtDisplayBoard,
DisplayBoardHelper.LogLevel.EMERG, "这是一条测试信息");
//查看TextBox的设置是否符合库最佳使用环境
string suggestion;
bool b = DisplayBoardHelper.IsConfigReasonable(
this.txtDisplayBoard, out suggestion);
if (!b)
{
MessageBox.Show(suggestion);
}
}
}
}
运行结果示例
DisplayBoardHelper.IsConfigReasonable生成的使用环境建议
