使用亚马逊的ECS示例 AWS SDK for .NET

以下代码示例向您展示如何在 Amazon 中使用来执行操作和实现常见场景ECS。 AWS SDK for .NET

操作是大型程序的代码摘录，必须在上下文中运行。您可以通过操作了解如何调用单个服务函数，还可以通过函数相关场景的上下文查看操作。

场景是向您展示如何通过在一个服务中调用多个函数或与其他 AWS 服务结合来完成特定任务的代码示例。

每个示例都包含一个指向完整源代码的链接，您可以在其中找到有关如何在上下文中设置和运行代码的说明。

开始使用

以下代码示例显示了如何开始使用 Amazon ECS。

        // Use your AWS profile name, or leave it blank to use the default profile.
        using var host = Host.CreateDefaultBuilder(args).Build();

        // Now the client is available for injection.
        var amazonECSClient = new AmazonECSClient();

        // You can use await and any of the async methods to get a response.
        var response = await amazonECSClient.ListClustersAsync(new ListClustersRequest { });
