Hello You can use HttpContext class to get the server path and it will automatically work based on the server. HttpContext.Current.Server.MapPath() Thanks

you can also inject IOptions wherever you need to access the configuration settings public class MailService { private readonly AppSettings _appSettings; public MailService(IOptions appSettings) { _appSettings = appSettings.Value; } public void SendMail() { string serverPath = _appSettings.ServerPath; // use serverPath to construct the button URL } }

You can define the configuration settings in the appsettings.json file, like this: { "AppSettings": { "ServerPath": "https://qa-server.com" } } and in your Startup.cs file, add the following code to read the configuration settings: public IConfiguration Configuration { get; } public Startup(IConfiguration configuration) { Configuration = configuration; } public void ConfigureServices(IServiceCollection services) { services.Configure (Configuration.GetSection("AppSettings")); // other service configurations } Here, AppSettings is a class that defines the configuration settings, public class AppSettings { public string ServerPath { get; set; } }

To make the server path configurable based on the environment, you can use the built-in configuration system in .NET Core.
