Question

Hi,

How to get list of registered services and run it manually?

            var app = WebApplication.Create();

            using var scope = app.Services.CreateScope();
            var services = scope.ServiceProvider;
            var itest = services.GetRequiredService<ITest>();

Answer 1

Hi @winanjaya could you try modifying your code to:

var app = WebApplication.Create();

using var scope = app.Services.CreateScope();
var services = scope.ServiceProvider;

var serviceList = services.GetServices<object>();

foreach (var service in serviceList) 
{
    Console.WriteLine(service.GetType().FullName);
}

var itest = services.GetRequiredService<ITest>();

Hello winanjaya,

Please try below code.

var app = WebApplication.Create();

using var scope = app.Services.CreateScope();
var services = scope.ServiceProvider;
var serviceList = services.GetServices<ITest>();

foreach (var service in serviceList)
{
    service.Run();
}

I have tried it, it returns empty.

below is one of my service that I put it in program.cs

builder.Services.AddSingleton<ITest, Test>();
builder.Services.AddHttpClient<ITest, Test>("test", c1 =>
{
    c1.BaseAddress = new Uri("https://xxx.xxxxx.com/api");
    c1.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
    c1.DefaultRequestHeaders.CacheControl = new CacheControlHeaderValue { NoCache = true };
    c1.Timeout = TimeSpan.FromMinutes(3);
})
    .SetHandlerLifetime(TimeSpan.FromMinutes(3))
    .ConfigureHttpClient((c2) =>
        new HttpClientHandler
        {
            ServerCertificateCustomValidationCallback = (sender, cert, chain,
            sslPolicyErrors) =>
            {
                return sslPolicyErrors == SslPolicyErrors.None;
            }
        }
    );
