我有一个名为 ICompleteConsumer 的接口，它只有一种方法，并且该接口有多个实现。

前任：

public class SampleClass1: ICompleteConsumer {

 public async Task Complete(Model model) {
  // do the work
 }
}

public class SampleClass2: ICompleteConsumer {

 public async Task Complete(Model model) {
  // do the work
 }
}

我像这样在启动中注册了这些

services.AddScoped<ICompleteConsumer, SampleClass1>(),
services.AddScoped<ICompleteConsumer, SampleClass2>(), 

我注入这些依赖项如下

public class ConsumerHandlerService(string message) {

 private readonly ICompleteConsumer completeConsumer;

 public ConsumerHandlerService(ICompleteConsumer completeConsumer) {
  this.completeConsumer = completeConsumer
 }

 switch (MessageType) {
  case (MessageType .1) //I want SampleClass1 implementation  to here
  var model = JsonConvert.DeserializeObject < Model > …
