NLog.Appsettings.Standard 1.0.0

An NLog Layout Renderer be used to access appsettings.json with .NET Standard 2.0.

Attention

The older package NLog.Appsetting.Standard is no longer updated and maintained. It is recommended to be replaced this new version.

How To Use

Install the NLog.Appsettings.Standard package from NuGet. You need add NLog 4.5 or higher, then put the syntax in your NLog configuration below:

<nlog>
    <extensions>
        <add assembly="NLog.Appsettings.Standard" />
    </extensions>
</nlog>

Configuration Syntax & Parameters

The layout renderer's name is appsettings, and syntax is ${appsettings:name=String.String2.String3:default=String}

• name - Key in your appsettings.<EnvironmentName>.json file. If it has a multi-level hierarchy that you want to access, you can separate by a dot. Required.
• default - Default value if not present. Optional.

Example

Target appsettings.json

{
    "Mode":"Prod",
    "Options":{
        "StorageConnectionString":"abcdefg123456789",
        "Container":"YourProdContainer"
    }
}

• ${appsettings:name=Mode} - Get "Prod" in this case.
• ${appsettings:name=Options.StorageConnectionString} - Get "abcdefg123456789" in this case.
• ${appsettings:name=Options.StorageConnectionString2:default=DefaultString} - Get "DefaultString" in this case.
