在C sharp中使用IniParser对ini配置文件进行读写操作

Mon, 18 Mar 2024 00:00:00 +0000

简介:

在这篇文章记录了在C sharp 编程中使用IniParse 对ini配置文件进行读写的操作.

读取ini文件中的Mysql数据库配置文件进行数据库连接:

如果你想从一个 .ini 文件中读取配置信息，可以使用第三方库，如 IniParser。以下是如何使用 IniParser 库来实现：

首先，你需要使用 NuGet 包管理器安装 IniParser。在 Visual Studio 中，可以通过 NuGet 包管理器控制台执行以下命令：
Install-Package IniParser
然后，创建一个 config.ini 文件，并添加以下内容：

[Database]
Server=your_server
User=your_user
Password=your_password
Database=your_database

接着，修改你的 mysqldata 类如下：

using System;
using IniParser;
using IniParser.Model;
using MySql.Data.MySqlClient;
using Sunny.UI;

namespace ExpressManageSystem
{
 internal class mysqldata
 {
 private static readonly string configFile = "config.ini";
 private static readonly FileIniDataParser parser = new FileIniDataParser();
 private static readonly IniData configData = parser.ReadFile(configFile);

 public static string connection_string
 {
 get
 {
 var databaseSection = configData["Database"];
 return $"server={databaseSection["Server"]};user={databaseSection["User"]};password={databaseSection["Password"]};database={databaseSection["Database"]}";
 }
 }

 public MySqlConnection mySqlConnection = new MySqlConnection(connection_string);

 //连接数据库
 public bool connect_db()
 {
 try
 {
 mySqlConnection.Open();
 return true;
 }
 catch (Exception ex)
 {
 UIMessageBox.Show(ex.Message);
 return false;
 }
 }

 //关闭数据库链接
 public bool close_db()
 {
 try
 {
 mySqlConnection.Close();
 return true;
 }
 catch (Exception ex)
 {
 UIMessageBox.Show(ex.Message);
 return false;
 }
 }
 }
}

在这个修改后的代码中，使用了 IniParser 库来读取 config.ini 文件中的配置信息。这样，你就可以通过修改 config.ini 文件来更改数据库连接信息，而无需修改代码。

网吧延迟启动工具以及源代码

Wed, 06 Dec 2023 00:00:00 +0000

缘由

好久没给网吧维护了，最近给日本网吧维护的时候，由于要在工作站开机启动之后执行一些初始化程序，要用到一个延迟启动程序。（程序是前辈写的，帮了很多忙。鞠躬）
但是在日本语系统下无法正常运行

报错如下：

如果要解决该错误，需要在区域选项中，将程式区域改为中国即可。如此一来会产生一个新的问题，某些程式会用区域来判断用户的location, 会导致一些软件无法正常运行。

于是我依葫芦画瓢，手搓了一个能在日本语系统下正常运行的延迟启动工具

功能和用法

简介
- 该延迟启动工具的本体只有一个exe执行文件和ini配置文件
- 执行文件会读取ini文件中的配置，然后执行相关任务
配置文件说明
- 配置文件包含TargetPath，FileExtensions，Timeout选项
- TargetPath：所需要执行的目录路径（绝对路径）
- FileExtenions: 需要执行的文件格式
- Timeout: 延迟时间毫秒为单位
用法
- 在给工作站开超级时，将Hiderun.exe 添加到系统启动项
- 根据你自身需求，在配置文件中“config.ini”填写相对应的路径和文件格式，以及时间。
日志
- 程序会在程序根目录生成log文件记录执行状态和报错，遇到问题可以在日志中查看明细。

C# Multidimensional Arrays

Tue, 04 Oct 2022 00:00:00 +0000

C# Multidimensional Arrays

As discussed in the previous chapter, Arrays in C# will support multi-dimensional arrays. In c#, a multidimensional array is an array that contains more than one dimension to represent the elements in a tabular format like rows and columns.
In c#, multidimensional arrays can support either two or three-dimensional series. To create multi-dimensional arrays, we need to use a comma (,) separator inside the square brackets.

C# Multi-Dimensional Array Declaration

In c#, Multidimensional Arrays can be declared by specifying the data type of elements followed by the square brackets [] with comma (,) separator. The following are examples of creating two or three-dimensional arrays in the c# programming language.
