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。

Coding Practice. Use an IP Guide retrieve your ip information

Intuduction

When we need to check some IP address information , do we have to open the browser, then type the googl domain and copy-paste the IP address?

In this article . I’m goinG to use python with IP GUIDE to check ipaddres information .This much better before.

Let’s started

Install Python

found what version can be match your OS , download it and installl .
https://www.python.org/downloads/

Install requests library

website: https://pypi.org/project/requests/
$ python -m pip install requests

Code

#import requests library
import requests

#get data from ip guide
response = requests.get(f'https://ip.guide/').json()

#function get_ip
def get_ip():
 return response["ip"]

#function get_location
def get_location():
 location_data = {
 "Latitude":response["location"]["latitude"],
 "Longitude" : response["location"]["longitude"],
 "City": response["location"]["city"],
 "Country": response["location"]["country"]
 }
 return location_data

#function get_network
def get_network():
 network_data = {
 "Cidr": response["network"]["cidr"],
 "Host Start" : response["network"]["hosts"]["start"],
 "Host end" : response["network"]["hosts"]["end"]
 }
 return network_data

#dictionary variable
network_data = get_network()
location_data = get_location()
ipaddress = get_ip()

# output information 
print(f"Your internet IPaddress is :{ipaddress}\n and below is this IPaddress other informations\n")

# for loop
for key,value in network_data.items():
 print(f"{key}: {value}")
print(" \n")

for key,value in location_data.items():
 print(f"{key}: {value}")
print(" \n")
