asp.net core 配置

Core中配置涉及的类结构

 

 

 

ConfgurationSource:相当于配饰的数据源，可以是内存，可以是配置文件。

ConfigurationBuilder ：配饰数据源的组装车间，负责取出数据源供配置类消费Configuration。

Configuration ：配置数据的映射

 

配置类定义：

 

public class CompanyInfoOptions

{

public CompanyInfoOptions(IConfiguration config)

{

this.Name=config["name"];

this.Address=config["address"];

this.CreateDate = DateTime.Parse( config["createDate"]);

}

public String Name

{

get;

set;

}

 

public String Address

{

get;

set;

}

 

public DateTime CreateDate

{

get;

set;

}

}

 

{
"companyInfo": {
"Name": "hbb0b0",
"address": "Xi‘AN JinYeLu number6",
"createDate": "2017/08/06"
}
}

注意配置文件在运行目录，与以前配置不同的配置文件不用拷贝到Bin目录。

 

Main中调用：

 

class Program

{

//Section 节名称

const string str_SectionCompanyInfo="companyInfo";

static void Main(string[] args)

{

Console.WriteLine(Directory.GetCurrentDirectory());

//ConfigtionBuilder初始化

var config = new ConfigurationBuilder()

.SetBasePath(Directory.GetCurrentDirectory())

.AddJsonFile("companyinfo.json", optional:true,reloadOnChange:true)

.Build();

//初始化CompanyInfoOptions

CompanyInfoOptions options= new CompanyInfoOptions(config.GetSection(str_SectionCompanyInfo));

 

//输出

Console.WriteLine($"name:{options.Name}");

Console.WriteLine($"address:{options.Address}");

Console.WriteLine($"createDate:{options.CreateDate.ToString()}");

}

}
