我有一个服务需要在项目管道内注入和使用
//Register Service
builder.Services.AddScoped<IDbInitializer, DbInitializer>();
//Build App and Inject Service
var app = builder.Build();
var dbInitializer = app.Services.GetService<IDbInitializer>();
//Use
dbInitializer.Initialize();
我将在注入此服务(或任何其他服务)时更新以下问题
为了需要作用域服务，您需要启动一个作用域，它将位于其中:https://learn.microsoft.com/en-us/aspnet/core/fundamentals/dependency-injection?view=aspnetcore-7.0#resolve-a-service-at-app-start-up
//Register Service
builder.Services.AddScoped<IDbInitializer, DbInitializer>();
//Build App and Inject Service
var app = builder.Build();
using (IServiceScope scope = app.Services.CreateScope())
{
IDbInitializer dbInitializer = scope.ServiceProvider.GetRequiredService<IDbInitializer>();
//Use
dbInitializer.Initialize();
}
