将 ListRoles 与 Amazon SDK 或命令行工具配合使用

    /// <summary>
    /// List IAM roles.
    /// </summary>
    /// <returns>A list of IAM roles.</returns>
    public async Task<List<Role>> ListRolesAsync()
    {
        var listRolesPaginator = _IAMService.Paginators.ListRoles(new ListRolesRequest());
        var roles = new List<Role>();

        await foreach (var response in listRolesPaginator.Responses)
        {
            roles.AddRange(response.Roles);
        }

        return roles;
    }

要列出当前账户的 IAM 角色

以下 list-roles 命令将列出当前账户中的 IAM 角色。

aws iam list-roles

输出：
