CodeGo.net>天空驱动器System.Dynamic.DynamicObject

我正在尝试获取SkyDrive上已登录用户的所有文件夹的列表.

LiveOperationResult operationResult = await client.GetAsync("me/skydrive/files");
dynamic result = operationResult.Result;

我希望能够执行以下操作：

Dictionary<string, object> folderData = (Dictionary<string, object>)result;
List<object> folders = (List<object>)folderData["data"];

foreach (object item in folders)
{
    Dictionary<string, object> folder = (Dictionary<string, object>)item;
    if (folder["name"].ToString() == "Folder Name")
    {
        showToastMessage(folder["id"].ToString());
        return;
    }
}

但是,在这一行：

Dictionary<string, object> folderData = (Dictionary<string, object>)result;

我收到一个错误：

Cannot convert type ‘System.Dynamic.DynamicObject’ to
‘System.Collections.Generic.Dictionary’

有谁知道我该如何解决这个问题？

解决方法:

问题在于LiveOperationResult.Result不一定保证是Dictionary< string,object>.但是,将其定义为IDictionary< string,object>.

请注意,您甚至不需要将Result属性转换为任何类型的字典.您应该能够使用动态变量直接访问要迭代的列表.

List<object> folders = (List<object>)result.data;
