我正在尝试用CloudFormation生成C#文件。不幸的是，无论我作为NetworkInterfaces在CfnInstance中传递什么，我都会得到一个错误。我翻阅了整个文档，找不到解决问题的办法。

这是我的C#堆栈。

                }
            };

            var networkInterface = new CfnNetworkInterface(this, "NetworkInterface", new CfnNetworkInterfaceProps()
            {
                GroupSet = new[] { sg.ToString() },
                SubnetId = subnet.Ref
            });

            new CfnInstance(this, "EC2", new CfnInstanceProps()

                InstanceType = "m5.xlarge",

                UserData = "test"
            });
        }
    }

不幸的是，异常的堆栈跟踪并没有清楚地说明问题。下面是堆栈跟踪本身：

我也曾试图通过

代码语言：javascript
复制
NetworkInterfaces = networkInterface
NetworkInterfaces = networkInterface.ToString()
NetworkInterfaces = new[] {networkInterface}
NetworkInterfaces = new[] {networkInterface.ToString()}

如果我从NetworkInteraces中删除CfnNetworkInterface属性，那么上面的代码可以正常工作。

我不明白问题出在哪里。我更改的所有内容都会导致上述情况下的相同异常。任何帮助都是非常感谢的。

提前谢谢你。

我能够使用TypeScript重新创建并修复API问题。我能合成堆栈。我相信这同样适用于C#。

代码语言：javascript
复制
new CfnInstance(this, "EC2", {
  networkInterfaces: [{
    deviceIndex: '0',
    groupSet: [sg.toString()],
    subnetId: subnet.ref
  }],
  imageId: "ami-id",
  instanceType: "t2.micro",
  keyName: "keyName",
  userData: "test"
});

问题在于CfnNetworkInterface在CfnInstance中的使用。CfnInstance中的属性CfnInstance.NetworkInterfaceProperty or cdk.IResolvable需要一个类型为CfnInstance.NetworkInterfaceProperty or cdk.IResolvable的数组。您现在提供给它的内容(CfnNetworkInterface)与预期的类型不匹配。我也很困惑地发现，我无法在上面的TS代码中导入CfnInstance.NetworkInterfaceProperty，但能够将对象表示法强制转换为IResolvable。

还请注意，当您使用CfnInstance.NetworkInterfaceProperty时，您还必须提供deviceIndex。希望这将解决C#代码中的问题。

PS:为了简洁起见，我已经将blockDeviceMappings从我的方法中删除了。
