1. 编辑项目文件

添加如下NuGet包

<PackageReference Include=Microsoft.Extensions.Configuration.Binder Version=6.0.0 />
<PackageReference Include=Microsoft.Extensions.Configuration.Json Version=6.0.0 />
<PackageReference Include=Microsoft.Extensions.Configuration.EnvironmentVariables Version=6.0.0 />

2.配置文件添加

appsettings.json文件

{
	AccessKeyId: abcdefghijklmnopqrst
}

3.读取配置文件

在方法中添加

using Microsoft.Extensions.Configuration;

//读取配置文件
IConfiguration config = new ConfigurationBuilder()
    .AddJsonFile(appsettings.json)
    .AddEnvironmentVariables()
    .Build();
string AccessKeyId = config[AccessKeyId];
string PostgreSQL= config.GetConnectionString(PostgreSQL);

扩展

static HomeClass()
{
    //读取配置文件
    IConfiguration config = new ConfigurationBuilder()
        .AddJsonFile(appsettings.json)
        .AddEnvironmentVariables()
        .Build();
    RedisConnectionString = config.GetConnectionString(Redis);
}
/// <summary>
/// 配置数据库地址
/// </summary>
private static readonly string RedisConnectionString;
