I have class library called Persistence.EFCore contains this method
public static IServiceCollection AddPersistenceServices(this IServiceCollection services, IConfiguration configuration)
{
services.AddDbContext<SIMContext>(options =>
options.UseSqlServer(configuration.GetConnectionString("ConnectionString")));
services.AddTransient<IUnitOfWork, UnitOfWork>();
return services;
}
and this is my code from Program.cs in winform project
public static IConfiguration Configuration { get; }
[STAThread]
static void Main()
{
ApplicationConfiguration.Initialize();
var builder = new HostBuilder()
.ConfigureAppConfiguration((hostContext, builder) =>
{
builder.AddJsonFile("apsettings.json", optional: true, reloadOnChange: true);
})
.ConfigureServices((hostContext, services) =>
{
services.AddScoped<XtraMain>();
services.AddPersistenceServices(Configuration);
services.AddApplicationServices();
services.AddTransient<FrmExpressionOfNeeds>();
services.AddSingleton<IFormFactory, FormFactory>();
});
var host = builder.Build();
using (var serviceScope = host.Services.CreateScope())
{
IServiceProvider services = serviceScope.ServiceProvider;
XtraMain mainform = services.GetRequiredService<XtraMain>();
System.Windows.Forms.Application.Run(mainform);
}
}
I can't find a way to set the Configuration value.
The Configuration from IConfiguration supposed to get his value from
Configuration = builder.Build();
But in my case the
services.AddPersistenceServices(Configuration);
came before the build
CodePudding user response:
The first parameter of ConfigureService((context, services)=>{ ... }) is HostBuilderContext which gives you access to configuration, using its Configuration property.
So assuming you have a service extension method which accepts configuration, then you can easily pass configuration to it using context.Configuration
.
Example
using Microsoft.Extensions.Hosting;
using Microsoft.Extensions.DependencyInjection;
internal static class Program
{
[STAThread]
static void Main()
{
ApplicationConfiguration.Initialize();
var host = CreateHostBuilder().Build();
Application.Run(host.Services.GetRequiredService<Form1>());
}
static IHostBuilder CreateHostBuilder() =>
Host.CreateDefaultBuilder()
.ConfigureServices((context, services) =>
{
services.AddHelloServices(context.Configuration);
services.AddTransient<Form1>();
});
}
