How To Read / Access Email Setting In Appsettings.json In Asp.Net Core 6 in Controller Using C#.Net

In this article i will show you how you can access or read the email setting from Appsettings.json file in asp.net core 6 / MVC application using c#.net. So for this first we will create a new asp.net core web application and add open the Appsettings.json file. In Appsettings.json file we will first add the email server setting as shown below.

"Smtp": {     "Host": "smtp.xxxx.com",     "EnableSsl": true,     "UserName": "admin@xxxx.com",     "FromEmail": "admin@xxxxx.com",     "Password": "iNxxxx123",     "DefaultCredentials": false,     "Port": 123   }

 

After this we will add the below code into the controller to access the email server setting or SMTP server setting from appsetting.json file.

var builder = new ConfigurationBuilder().SetBasePath(Directory.GetCurrentDirectory()).AddJsonFile("appsettings.json", optional: false);             IConfiguration config = builder.Build();             string host = config.GetValue<string>("Smtp:Host");             string username = config.GetValue<string>("Smtp:UserName");             string fromemailid = config.GetValue<string>("Smtp:FromEmail");             string password = config.GetValue<string>("Smtp:Password");             string defaultcredentials = config.GetValue<string>("Smtp:DefaultCredentials");             string port = config.GetValue<string>("Smtp:Port");             string enablessl = config.GetValue<string>("Smtp:EnableSsl");

 In 

In above code i have used ConfigurationBuilder to read the appsettings.json file. The name space for ConfigurationBuilder is Microsoft.Extensions.Configuration. Now we will add the code to display it on controller view. 

public IActionResult Index()         {             var builder = new ConfigurationBuilder().SetBasePath(Directory.GetCurrentDirectory()).AddJsonFile("appsettings.json", optional: false);             IConfiguration config = builder.Build();             string host = config.GetValue<string>("Smtp:Host");             string username = config.GetValue<string>("Smtp:UserName");             string fromemailid = config.GetValue<string>("Smtp:FromEmail");             string password = config.GetValue<string>("Smtp:Password");             string defaultcredentials = config.GetValue<string>("Smtp:DefaultCredentials");             string port = config.GetValue<string>("Smtp:Port");             string enablessl = config.GetValue<string>("Smtp:EnableSsl");             StringBuilder stringBuilder = new StringBuilder();             stringBuilder.Append("Host: " + host + "<br/>");             stringBuilder.Append("UserName: " + username + "<br/>");             stringBuilder.Append("FromEmail: " + fromemailid + "<br/>");             stringBuilder.Append("Password: " + password + "<br/>");             stringBuilder.Append("DefaultCredentials: " + defaultcredentials + "<br/>");             stringBuilder.Append("Port: " + port + "<br/>");             stringBuilder.Append("EnableSsl: " + enablessl + "<br/>");             ViewBag.Data = stringBuilder.ToString();             return View();         }

 

Now lets write code to display the accessed configuration setting in controller view.

@{     ViewData["Title"] = "Home Page"; } <div>     @ViewBag.Data </div>

 

Now we have done run the code and check the output. But before checking the final output lets put the break point and check whether we are able to access the detail or not.  so here we can see we are able to access the detail.

Now lets check the output.
