Как записать данные в appsettings.json в консольном приложении (.net Core)? ⇐ C#

[Anonymous]

Чтобы прочитать данные из appsettings.json я используюConfigurationBuilder, ConfigurationBinder.

 
 ConfigurationBuilder,ConfigurationBinder allow you to read data from appsettings.json.

Questions:

- How to write data to appsettings.json in a console application?

Can I write data to appsettings.json usingConfigurationBuilder, ConfigurationBinder?

Или мне нужно использовать JsonConvert.DeserializeObject (fileText) для записи данных в appsettings.json?

Другими словами, если вы используете JsonConvert.DeserializeObject, то мне следует:

- прочитать данные appsettings.json;

- измените данные в нужном
разделе;

- сохраните данные в appsettings.json.

 Мне нужно понимаете логику работы с appsettings.json?

Код AppSettings.cs

namespace ConsoleAppCore
{
class AppSettings
{
public string KeyA_SecMain { get; set; }
public string KeyB_SecMain { get; set; }
}
}


Код appsettings.json

{
"SectionMain": {
"KeyA_SecMain": "KeyA_SecMain_Value",
"KeyB_SecMain": "KeyB_SecMain_Value"
}
}


Код ReadWriteAppSettings.cs

using Microsoft.Extensions.Configuration;
using System.IO;

namespace ConsoleAppCore
{
class ReadWriteAppSettings
{
///
/// Read GetSection AppSettings
///
///
public string ReadGetSectionAppSettings()
{
var builder = new ConfigurationBuilder()
.SetBasePath(Directory.GetCurrentDirectory())
.AddJsonFile("appsettings.json", optional: true, reloadOnChange: true);

IConfigurationRoot configuration = builder.Build();

string result = configuration.GetSection("SectionMain:KeyA_SecMain").Value;

return result;
}

///

{
AppSettings appSettings = new AppSettings();

var builder = new ConfigurationBuilder()
.SetBasePath(Directory.GetCurrentDirectory())
.AddJsonFile("appsettings.json", optional: true, reloadOnChange: true);

var configuration = builder.Build();

var configurationResult = configuration.GetSection("SectionMain");

ConfigurationBinder.Bind(configurationResult, appSettings);

string result_KeyA_Sec1 = appSettings.KeyA_SecMain;
string result_KeyB_Sec1 = appSettings.KeyB_SecMain;
}
}
}


Код Program.cs

namespace ConsoleAppCore
{
class Program
{
static void Main(string[] args)
{
ReadGetSectionAppSettings();
BindAppSettings();
}

static public string ReadGetSectionAppSettings()
{
ReadWriteAppSettings readWriteAppSettings = new ReadWriteAppSettings();
string str = readWriteAppSettings.ReadGetSectionAppSettings();

return str;
}

static public void BindAppSettings()
{
ReadWriteAppSettings readWriteAppSettings = new ReadWriteAppSettings();
readWriteAppSettings.BindAppSettings();
}

}
}
