Read string of json values from config file c#

Question

I have json object which is reading like configuration.Getsection("XYZconfig").Get(); in code it is working fine in local. After inserting the config values in azure keyvault the XYZconfig section is taking as below, The quotation is appending before and after brackets. so it is unable to read using configuration.Getsection("XYZconfig").Get(). How to read this config values.

"XYZconfig": "{ "key1":"vaule1", "key2":"value2", "key3":"value3" }"

you can use Trim like var configSection = configuration.GetSection("XYZconfig").Value.Trim('"'); — Vivek Nuna

Hi @Jajula Siva, have you tried using Newtonsoft.Json to handle escaped strings which like mjb said: var XYZconfig = _configuration.GetSection("XYZconfig").Value; var key1 = JObject.Parse(XYZconfig).GetValue("key1");? — Chen

To access the configuration values you stored in Azure KeyVault from your ASP.NET Core web app, you can refer to following code snippet:

public static IHostBuilder CreateHostBuilder(string[] args) =>
    Host.CreateDefaultBuilder(args)
    .ConfigureAppConfiguration((context, config) =>
    {

        var root = config.Build();
        config.AddAzureKeyVault($"https://{your_keyvault_name_here}.vault.azure.net/", $"{clientid_here}", $"{client_secret_here}");
    })
    .ConfigureWebHostDefaults(webBuilder =>
    {
        webBuilder.UseStartup<Startup>();
    });

Read configuration value:

private readonly ILogger<HomeController> _logger;
private readonly IConfiguration _config;

public HomeController(ILogger<HomeController> logger, IConfiguration config)
{
    _logger = logger;
    _config = config;
}

public async Task<IActionResult> Index()
{
    var val = _config["XYZconfig"];
