# 你好 EventBridge
<a name="example_eventbridge_Hello_section"></a>

以下代码示例展示了如何开始使用 EventBridge。

------
#### [ .NET ]

**适用于 .NET 的 SDK**  
 还有更多相关信息 GitHub。在 [AWS 代码示例存储库](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/dotnetv3/EventBridge#code-examples)中查找完整示例，了解如何进行设置和运行。

```
using Amazon.EventBridge;
using Amazon.EventBridge.Model;

namespace EventBridgeActions;

public static class HelloEventBridge
{
    static async Task Main(string[] args)
    {
        var eventBridgeClient = new AmazonEventBridgeClient();

        Console.WriteLine($"Hello Amazon EventBridge! Following are some of your EventBuses:");
        Console.WriteLine();

        // You can use await and any of the async methods to get a response.
        // Let's get the first five event buses.
        var response = await eventBridgeClient.ListEventBusesAsync(
            new ListEventBusesRequest()
            {
                Limit = 5
            });

        foreach (var eventBus in response.EventBuses)
        {
            Console.WriteLine($"\tEventBus: {eventBus.Name}");
            Console.WriteLine($"\tArn: {eventBus.Arn}");
            Console.WriteLine($"\tPolicy: {eventBus.Policy}");
            Console.WriteLine();
        }
    }
}
