Examples
(.env [environment variables])
MyConfigItem=Test Value
Subclass_MyConfigSubItem=Test Subitem Value
(MyConfiguration.cs)
public class MyConfiguration
{
public string MyConfigItem { get; set; }
public MyConfigSubClass Subclass { get; set; }
}
public class MyConfigSubClass
{
public string MyConfigSubItem { get; set; }
}
(Program.cs)
public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.UseEnvironmentConfiguration<MyConfiguration>()
.....
(Startup.cs)
public class Startup
{
private readonly MyConfiguration _configuration;
public Startup(MyConfiguration configuration)
{
_configuration = configuration;
}
public void ConfigureServices(IServiceCollection services)
{
...
Console.WriteLine(_configuration.MyConfigItem);
Console.WriteLine(_configuration.Subclass.MyConfigSubItem);
...
}
}
If you want, you can re-map the name of the items using [ConfigurationItem]: (Do note, [ConfigurationItem] is not required and only needed if you want to set the requirement policy of a property or change the name of the environment variable)
public class MyConfiguration
{
[ConfigurationItem("MyItem")]
public bool Item { get; set; }
// OR
[ConfigurationItem(Name = "MyOtherItem")]
public int OtherItem { get; set; }
[ConfigurationItem("Test")
public SubConfiguration MySubClass { get; set; }
}
public class SubConfiguration
{
[ConfigurationItem]
public bool SubItem { get; set; }
}
If you want to ignore parsing certain properties in a class, you can use [ConfigurationItem(Ignore = true)]:
public class MyConfiguration
{
[ConfigurationItem("MyItem")]
public bool Item { get; set; }
public int OtherItem { get; set; }
[ConfigurationItem(Ignore = true)]
public SubConfiguration MySubClass { get; set; }
}
The environment variables for this would look like as follows:
MyItem=Value
MyOtherItem=Value
Test_SubItem=Value
You can also set if the item is required to be set in the environment or not. By default, items are required.
public class MyConfiguration
{
[ConfigurationItem(Required = false)]
public bool NotRequiredItem { get; set; }
// OR
[ConfigurationItem(Name = "MyOtherItem", Required = true)]
public int OtherItem { get; set; }
}
If you want to specify a default value for an item if it's not required:
public class MyConfiguration
{
[ConfigurationItem(Required = false, Default = true)]
public bool NotRequiredItem { get; set; }
// OR
[ConfigurationItem(Required = false, Default = 123)]
public int OtherItem { get; set; }
}
Conversions across types are supported for defaults, for instance:
(string)"123" => (int)123
(string)"true" => (bool)True
(string)"false" => (bool)False
(int)1 => (bool)True
(int)0 => (bool)False
...etc
From an Env File:
Most of this applies from above, except instead your IWebHostBuilder would look like:
// Program.cs
public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.UseEnvironmentConfiguration<MyConfiguration>(fileName: "filename.env", configurationTypeEnum: ConfigurationTypeEnum.PreferEnvironment)
.....
Non-DI:
To parse environment variables directly:
public void MyFunction()
{
var output = ConfigurationParser.Parse<MyClass>();
// Access your class via output variable
}
To parse from an environment file:
public void MyFunction()
{
var output = ConfigurationParser.Parse<MyClass>(fileName: "file.env");
// Access your class via output variable
}
Preferences
You can choose one of the following preferences:
- Prefer Environment Over File
- Prefer File Over Environment
- Use Environment Only
- Use File Only
The default functionality is Prefer Environment over File.
To use this functionality, there's two ways, both DI and non-DI:
DI
// Program.cs
public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.UseEnvironmentConfiguration<MyConfiguration>(fileName: "filename.env", configurationTypeEnum: ConfigurationTypeEnum.PreferEnvironment)
.....
Non-DI
public void MyFunction()
{
var output = ConfigurationParser.Parse<MyClass>(fileName: "file.env", configurationTypeEnum: ConfigurationTypeEnum.PreferEnvironment);
.....
}
Manual-DI (for non asp.net core projects)
public void Main()
{
var servicesBuilder = new ServiceCollection();
var output = ConfigurationParser.Parse<MyClass>(fileName: "file.env", configurationTypeEnum: ConfigurationTypeEnum.PreferEnvironment);
servicesBuilder.AddSingleton(output);
var services = servicesBuilder.BuildServiceProvider();
// Access MyClass in constructor or like below
var config = services.GetService<MyClass>();
.....
}
POSIX style variables
public void MyFunction()
{
var output = ConfigurationParser.ParseConfigurationPosix<MyClass>();
.....
}
// or with options
public void MyFunction()
{
var output = ConfigurationParser.ParsePosix<MyClass>(fileName: "file.env", configurationTypeEnum: ConfigurationTypeEnum.PreferEnvironment);
.....
}
or builder syntax:
// Program.cs
public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.UseEnvironmentConfigurationPosix<MyConfiguration>(fileName: "filename.env", configurationTypeEnum: ConfigurationTypeEnum.PreferEnvironment)
.....
Json Support
If you want to support json objects, you can do so via the Json
attribute.
[ConfigurationItem(Json = true)]
public List<string> MyList { get; set; }
Config:
MyList = ["Item1","Item2","Item3","Item4"]
Multiline
You can also use multiline capability for more easily readable json objects.
public class MyItem
{
public string Name { get; set; }
public int Value { get; set; }
}
// in your config class:
...
[ConfigurationItem(Json = true)]
public MyItem Item { get; set; }
Config:
Item = `{
"Name": "My Item!",
"Value": 42
}`
