How to check folder exist or not and how to upload image using URL using C#

Didn't get much about SvaeUrlAsync but I used this and it worked perfectly.

List<Images> fiveElements = Images.GetRange(0, 5);
            foreach (var image in fiveElements)
            {
                WebClient webclient = new WebClient();
                var stream = new MemoryStream(webclient.DownloadData(image.ImageURL));
                var fileName = "Test1.jpg";
                var response = await client.Files.UploadAsync(path + "/" + fileName, WriteMode.Overwrite.Instance, true, body: stream);
            }

And for try catch I used your code but not working well as it throws me out of this method and goes to catch(Exception e) of parent method.

try
            {
                await client.Files.GetMetadataAsync(path);
            }
            catch (ApiException<Dropbox.Api.Files.GetMetadataError> e)
            {
                if (e.ErrorResponse.IsPath && e.ErrorResponse.AsPath.Value.IsNotFound)
                {
                    Console.WriteLine("Nothing found at path.");
                }
                else
                {
                    // different issue; handle as desired
                    Console.WriteLine(e);
                }
            }

Please let me know where I am going wrong.
Thank you.

Thank you so much for the help. Using await and removing result worked for me.

try
            {
                await client.Files.GetMetadataAsync(path);
            }
            catch (ApiException<Dropbox.Api.Files.GetMetadataError> e)
            {
                if (e.ErrorResponse.IsPath && e.ErrorResponse.AsPath.Value.IsNotFound)
                {
                    Console.WriteLine("Nothing found at path.");
                }
                else
                {
                    // different issue; handle as desired
                    Console.WriteLine(e);
                }
            }
