Check Whether a Particular Folder Exists in Your OneDrive Using Live SDK

This is a quick post on how you can check whether a particular folder exists in your OneDrive using Live SDK. My requirement here was, for one of my Windows Phone 8 applications, I needed to check whether a particular folder exists in my OneDrive. Following is a very simple method for that.

private static async Task<string> CheckIfFolderExistsAsync(LiveConnectClient client, string folderName)

{

    LiveOperationResult operationResult = await client.GetAsync("me/skydrive/files?filter=folders,albums");

    dynamic result = operationResult.Result;

    foreach (var item in result.data)

    {

        if (item.name == folderName)

        {

            return item.id;

        }

    }

    return string.Empty;

}

If a folder exists under given name, it will return the id of the folder and if not, an empty string will be returned.

Happy Coding.
