Best way to get a file's URL

Greg,

Is is possible you could post a snippet of C# code that shows how to call an async method from another class?   I want to have a class called DropboxManager where I can put all of the Dropbox code in and then call those methods.  But I can't figure out how to pass parameters without another level of indirection.  Here are some code snippets to help you understand.  This is in the Form_Load method of my Windows Form application

this.dbx = DropboxManager.GetUserToken(this.DropboxDevelopmentAccessToken);

Task<FullAccount> task = Task.Run(GetCurrentAccount);
task.Wait();
this.full = task.Result;

this.lblDropboxUserName.Text = full.Name.DisplayName;
this.lblDropboxEmailAddress.Text = full.Email;

Task<List<string>> task1 = Task.Run(ListFolders);
task1.Wait();
int i = task1.Result.Count;

Here are the functions that are another level of indirection and in the same class as the Form_Load method.

async Task<List<string>> ListFolders()
{
	DropboxManager dm = new DropboxManager();
	List<string> FolderList = await dm.ListFolders(dbx);

	return FolderList;
}

async Task<FullAccount> GetCurrentAccount()
{
	try
	{
		DropboxManager dm = new DropboxManager();
		return await dm.GetCurrentAccount(dbx);
	}
	catch (Exception e)
	{
		throw e;
	}
}

Here are the methods that are called in my DropboxManager class:

public async Task<List<string>> ListFolders(DropboxClient dbx)
{
	try
	{
		List<string> FolderList = new List<string>();
		var list = await dbx.Files.ListFolderAsync(string.Empty);

		foreach (var item in list.Entries.Where(i => i.IsFolder))
		{
			FolderList.Add(item.Name);
		}

		return FolderList;
	}
	catch (Exception ex)
	{
		throw ex;
	}
}

public static DropboxClient GetUserToken(string oauth2AccessToken)
{
	try
	{
		DropboxClient dbx = new DropboxClient(oauth2AccessToken);
		return dbx;
	}
	catch (Exception e)
	{
		throw e;
	}
}

public async Task<FullAccount> GetCurrentAccount(DropboxClient dbx)
{
	try
	{
		return await dbx.Users.GetCurrentAccountAsync();
	}
	catch (Exception e)
	{
		throw e;
	}
}

So you can see that the only way I can pass parameters is by executing a Run() on an async function that calls another async function.  I can't figure out how to pass parameters from that first level.  Is that even possible?

Thanks.
