When you create a new Blazor project, you get an appsettings.json file in the structure to get the settings conatined therein at startup. How do you implement it for a .NET Core Console app?
There is a good reference on this Adding AppSettings.json Configuration to a .NET Core Console Application, Whist I found it did not work completely as specified, I was able to so with some tweeking.
The appseetting.json file
{
"PathToRepository": "C:\\Users\\me\\Downloads\\azure-iot-samples-csharp-master_src\\azure-iot-samples-csharp-master",
"PathToRepositoryAlt": "\\Users\\me\\source\\dotnet-iot\\iot",
}
Code to access it
string DefaultPath = Configuration.GetValue<string>("PathToRepository");
string DefaultPathAlt = Configuration.GetValue<string>("PathToRepositoryAlt");
Using Declaration
using Microsoft.Extensions.Configuration;
Packages to include
Get them via Nuget
<ItemGroup>
<PackageReference Include="Microsoft.Extensions.Configuration" Version="3.1.6" />
<PackageReference Include="Microsoft.Extensions.Configuration.Binder" Version="3.1.6" />
<PackageReference Include="Microsoft.Extensions.Configuration.Json" Version="3.1.6" />
<PackageReference Include="Microsoft.Extensions.DependencyInjection" Version="3.1.6" />
<PackageReference Include="Microsoft.Extensions.FileProviders.Physical" Version="3.1.6" />
</ItemGroup>
Note not all of these packages are required for the functionality demonstrated here.
The Scaffolding at the start of the appp
var builder = new ConfigurationBuilder()
.SetBasePath(Directory.GetCurrentDirectory())
.AddJsonFile("appsettings.json", optional: true, reloadOnChange: true);
Microsoft.Extensions.Configuration.IConfiguration Configuration = builder.Build();
