 ### Injecting DaprClient
 
+ABP registers the `DaprClient` class to the [dependency injection](../Dependency-Injection.md) system. So, you can inject and use it whenever you need:
+
+````csharp
+public class MyService : ITransientDependency
+{
+    private readonly DaprClient _daprClient;
+
+    public MyService(DaprClient daprClient)
+    {
+        _daprClient = daprClient;
+    }
+
+    public async Task DoItAsync()
+    {
+        // TODO: Use the injected _daprClient object
+    }
+}
+````
+
+Injecting `DaprClient` is the recommended way of using it in your application code. When you inject it, the `IAbpDaprClientFactory` service is used to create it, which is explained in the next section.
+
 ### IAbpDaprClientFactory
 
 `IAbpDaprClientFactory` can be used to create `DaprClient` or `HttpClient` objects to perform operations on Dapr. It uses `AbpDaprOptions`, so you can configure the settings in a central place.

 ### 注入DaprClient
 
+ABP 将 `DaprClient` 类注册到 [依赖注入](../Dependency-Injection.md) 系统中.因此,你可以在需要时注入并使用它:
+
+````csharp
+public class MyService : ITransientDependency
+{
+    private readonly DaprClient _daprClient;
+
+    public MyService(DaprClient daprClient)
+    {
+        _daprClient = daprClient;
+    }
+
+    public async Task DoItAsync()
+    {
+        // TODO: Use the injected _daprClient object
+    }
+}
+````
+
+注入 `DaprClient` 是在应用程序代码中使用它的推荐方法.当你注入它时,将使用 `IAbpDaprClientFactory` 服务创建它,这会在下一节中将进行说明.

 ### IAbpDaprClientFactory
 
 `IAbpDaprClientFactory` 可用于创建 `DaprClient` 或 `HttpClient` 对象来执行对 Dapr 的操作.它使用 `AbpDaprOptions`,因此你可以配置设置.
