标签:directory config str1 引用 com rect console 配置系统 新版
? 1.以前的配置文件格式为XML
? 2.新版的配置文件格式支持 { json ,xml, ini, memory, command, env..... }
Json文件 【Microsoft.Extensions.Configuration.Json】
添加配置文件json文件,并设置内容
{
"DataBase": {
"SqlServer": {
"ConnectionString": "server=.;database=testdb;uid=sa;pwd=123;"
},
"MySql": {
"IpAddress": "127.0.0.1",
"port": 3306
}
},
"endArray": [
{ "endId": 20 },
{ "endId": "30" }
]
}
获取数据
private static void Main(string[] args)
{
IConfiguration configuration = new ConfigurationBuilder()
.SetBasePath(Environment.CurrentDirectory)
.AddJsonFile("AppSettings.json",true,true)
.AddInMemoryCollection()
.Build();
var str1 = configuration["DataBase:SqlServer:ConnectionString"];
var str2 = configuration["endArray:0:endId"];
Console.WriteLine($"{str1}+---{str2}");
}
1.添加引用【Microsoft.Extensions.Configuration.Binder】
2.GetValue方式获取
private static void Main(string[] args)
{
IConfiguration configuration = new ConfigurationBuilder()
.SetBasePath(Environment.CurrentDirectory)
.AddJsonFile("AppSettings.json",true,true)
.AddInMemoryCollection()
.Build();
//GetValue获取方式
int val = configuration.GetValue<int>("endArray:0:endId");
Console.WriteLine(val);
}
3.实体映射方式
private static void Main(string[] args)
{
IConfiguration configuration = new ConfigurationBuilder()
.SetBasePath(Environment.CurrentDirectory)
.AddJsonFile("AppSettings.json",true,true)
.AddInMemoryCollection()
.Build();
//Bind 获取方式
Root root=new Root();
configuration.Bind(root);
var ip = root.DataBase.MySql.IpAddress;
var entid = root.endArray[0].endId;
Console.WriteLine($"{ip}{entid}");
//Get<T> 获取
var root = configuration.Get<Root>();
var ip = root.DataBase.MySql.IpAddress;
var entid = root.endArray[0].endId;
Console.WriteLine($"{ip}{entid}");
}
//这里是实体类
public class SqlServer
{
/// <summary>
///
/// </summary>
public string ConnectionString { get; set; }
}
public class MySql
{
/// <summary>
///
/// </summary>
public string IpAddress { get; set; }
/// <summary>
///
/// </summary>
public int port { get; set; }
}
public class DataBase
{
/// <summary>
///
/// </summary>
public SqlServer SqlServer { get; set; }
/// <summary>
///
/// </summary>
public MySql MySql { get; set; }
}
public class EndArray
{
/// <summary>
///
/// </summary>
public int endId { get; set; }
}
public class Root
{
/// <summary>
///
/// </summary>
public DataBase DataBase { get; set; }
/// <summary>
///
/// </summary>
public List<EndArray> endArray { get; set; }
}
