201.C# Configuration读取Ini文件

摘要

C# 是一种常用的面向对象编程语言，常用于开发 Windows 应用程序、Web 应用程序和游戏等。C# 的开发者可以使用 Configuration 类来读取 INI 文件。INI 文件是一种常见的配置文件格式，它可以存储一些配置信息，如程序的数据、用户的偏好设置等。

安装Microsoft.Extensions.Configuration.Ini

创建一个ini文件

[DbInfo]
Server=127.0.0.1
Uid=sa
password=123
DataBase="TestDb"

[EmailInfo]
Email="[email protected]"
Name="admin"
Password="123"
SmtpServer="[email protected]"
           

创建一个DbInfo类

public class DbInfo
{
    public static string Uid { get; set; }
    public static string Password { get; set; }
    public static string Ip { get; set; }

}

           

读取配制

ConfigurationBuilder builder = new ConfigurationBuilder();
builder.AddIniFile("config.ini");
IConfigurationRoot root= builder.Build();

DbInfo.Ip =root["DbInfo:Server"];
DbInfo.Uid = root["DbInfo:Uid"];
DbInfo.Password = root["DbInfo:Password"];

           

映射到类

var emailInfo=root.GetSection("EmailInfo").Get<EmailInfo>();
           

读取到界面

private void btnRead_Click(object sender, EventArgs e)
{
    ConfigurationBuilder builder = new ConfigurationBuilder();
    builder.AddIniFile("config.ini");
    IConfigurationRoot root = builder.Build();

    DbInfo.Ip = root["DbInfo:Server"];
    DbInfo.Uid = root["DbInfo:Uid"];
    DbInfo.Password = root["DbInfo:Password"];

    var emailInfo = root.GetSection("EmailInfo").Get<EmailInfo>();

    txtUid.Text = DbInfo.Uid;
    txtDbPassword.Text = DbInfo.Password;
    txtIp.Text = DbInfo.Ip;

    txtEmail.Text = emailInfo.Email;
    txtPassword.Text= emailInfo.Password;
    txtName.Text = emailInfo.Name;
    txtSmtp.Text = emailInfo.SmtpServer;
}
