dotenv.net 2.1.0

dotenv.net

dotenv.net is a zero-dependency module that loads environment variables from a .env environment variable file into System.Environment.

Usage

Conventional

First install the library as a dependency in your application from nuget

Install-Package dotenv.net

or

dotnet add package dotenv.net

or for paket

paket add dotenv.net

Create a file with no filename and an extension of .env.

A sample .env file would look like this:

DB_HOST=localhost
DB_USER=root
DB_PASS=s1mpl3

in the Startup.cs file or as early as possible in your code add the following:

using dotenv.net;

...

DotEnv.Config();

At times the .env would not be in the same directory as your assembly, in that case the following would apply

using dotenv.net

...

var success = DotEnv.AutoConfig();
if(success)
{
  // env successfully found and read
}

this looks through your assembly's folder and three folders up for a .env file and loads that.

the values saved in your .env file would be availale in your application and can be accessed via:

Environment.GetEnvironmentVariable("DB_HOST"); // would output 'localhost'
