Retrieve keys from Authorization keys function level authorization in Azure using C#

Question

I need to get the keys through code, not through a portal. For doing this I have found REST API in Google. This is the link to Azure Key management API, but do this we need to do an authentication.

We have to develop all this using C# only.

Regarding the issue, please refer to the following code.

 #install Microsoft.Azure.Management.ResourceManager.Fluent and Microsoft.Azure.Management.Fluent    
string clientId = "client id";
     string secret = "secret key";
     string tenant = "tenant id";
     var functionName ="functionName";
     var webFunctionAppName = "functionApp name";
     string resourceGroup = "resource group name";
     var credentials = new AzureCredentials(new ServicePrincipalLoginInformation { ClientId = clientId, ClientSecret = secret}, tenant, AzureEnvironment.AzureGlobalCloud);
     var azure = Azure
              .Configure()
              .Authenticate(credentials)
              .WithDefaultSubscription();

     var webFunctionApp = azure.AppServices.FunctionApps.GetByResourceGroup(resourceGroup, webFunctionAppName);
     var ftpUsername = webFunctionApp.GetPublishingProfile().FtpUsername;
     var username = ftpUsername.Split('\\').ToList()[1];
     var password = webFunctionApp.GetPublishingProfile().FtpPassword;
     var base64Auth = Convert.ToBase64String(Encoding.Default.GetBytes($"{username}:{password}"));
     var apiUrl = new Uri($"https://{webFunctionAppName}.scm.azurewebsites.net/api");
     var siteUrl = new Uri($"https://{webFunctionAppName}.azurewebsites.net");
     string JWT;
     using (var client = new HttpClient())
      {
         client.DefaultRequestHeaders.Add("Authorization", $"Basic {base64Auth}");

         var result = client.GetAsync($"{apiUrl}/functions/admin/token").Result;
         JWT = result.Content.ReadAsStringAsync().Result.Trim('"'); //get  JWT for call funtion key
       }
     using (var client = new HttpClient())
     {
        client.DefaultRequestHeaders.Add("Authorization", "Bearer " + JWT);
        var key = client.GetAsync($"{siteUrl}/admin/functions/{functionName}/keys").Result.Content.ReadAsStringAsync().Result;
      }
