#### [ .NET ]

**適用於 .NET 的 SDK**  
 GitHub 上提供更多範例。尋找完整範例，並了解如何在 [AWS 程式碼範例儲存庫](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/dotnetv3/Organizations#code-examples)中設定和執行。

```
    using System;
    using System.Threading.Tasks;
    using Amazon.Organizations;
    using Amazon.Organizations.Model;

    /// <summary>
    /// Lists the AWS Organizations organizational units that belong to an
    /// organization.
    /// </summary>
    public class ListOrganizationalUnitsForParent
    {
        /// <summary>
        /// Initializes the Organizations client object and then uses it to
        /// call the ListOrganizationalUnitsForParentAsync method to retrieve
        /// the list of organizational units.
        /// </summary>
        public static async Task Main()
        {
            // Create the client object using the default account.
            IAmazonOrganizations client = new AmazonOrganizationsClient();

            var parentId = "r-0000";

            var request = new ListOrganizationalUnitsForParentRequest
            {
                ParentId = parentId,
                MaxResults = 5,
            };

            var response = new ListOrganizationalUnitsForParentResponse();
            try
            {
                do
                {
                    response = await client.ListOrganizationalUnitsForParentAsync(request);
                    response.OrganizationalUnits.ForEach(u => DisplayOrganizationalUnit(u));
                    if (response.NextToken is not null)
                    {
                        request.NextToken = response.NextToken;
                    }
                }
                while (response.NextToken is not null);
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
        }

        /// <summary>
        /// Displays information about an Organizations organizational unit.
        /// </summary>
        /// <param name="unit">The OrganizationalUnit for which to display
        /// information.</param>
        public static void DisplayOrganizationalUnit(OrganizationalUnit unit)
        {
            string accountInfo = $"{unit.Id} {unit.Name}\t{unit.Arn}";

            Console.WriteLine(accountInfo);
        }
    }

#### [ CLI ]

**AWS CLI**  
**擷取父 OU 或根帳戶中的 OU 清單**  
下列範例示範如何取得指定根帳戶中的 OU 清單：  

```
aws organizations list-organizational-units-for-parent --parent-id r-examplerootid111
```
輸出顯示指定的根帳戶包含兩個 OU 並顯示每個的詳細資訊：  

```
{
        "OrganizationalUnits": [
                {
                        "Name": "AccountingDepartment",
                        "Arn": "arn:aws:organizations::o-exampleorgid:ou/r-examplerootid111/ou-examplerootid111-exampleouid111"
                },
                {
                        "Name": "ProductionDepartment",
                        "Arn": "arn:aws:organizations::o-exampleorgid:ou/r-examplerootid111/ou-examplerootid111-exampleouid222"
                }
        ]
}
```
