DropBox: how to upload files to DropBox using code

DropBox is a great little service that simply “just works”. If you have a DropBox account and wish to operate this from code, you have to know a great deal about REST and other “webby” stuff to communicate with the DropBox account. But, a great little library exists that shields you from all of this. On “github” (what ever that means?) ) you will find the DropNet library that helps you out here. It will allow you to operate the DropBox account quite easily.

How to do ?
1) Register a developer account at Dropbox.com
2) Obtain the ‘key’ and ‘secret’ from DropBox.com (found under ‘My Apps’)
3) Call into the users DropBox account like below

static void Main(string[] args)
var client = new DropNet.DropNetClient("32131rwzxynxo50t", "fwwesodkiwud8");

client.Login("user@domain.com", "password");

Console.WriteLine("Uploading file...");

//update file (testfile1.txt) -> dropbox
byte[] rawData = File.ReadAllBytes("textfile1.txt");
var result = client.UploadFile("Test", "textfile1.txt", rawData);

Console.WriteLine("Status = {0}", result.StatusCode);

As evident from the sample, you can stream the file to DropBox using the client.UploadFile(<folder>, <filename>, <raw bytes>).

Hello Sir,

Could you explain these lines of code:

var client = new DropNet.DropNetClient("32131rwzxynxo50t", "fwwesodkiwud8");

client.Login("user@domain.com", "password");

var client = ...: Instantiation of a new client object. The arguments passed here are dropbox specific keys to identity your client applicication to Dropbox(NOT you as a user!)

clint.login(...): To authenticate yourself to dropbox.

How do we download a file from dropbox using .net

And when we upload does it generate any link?

client.Login("...", "..."); is no longer supported in the last version of DropNet. How is it replaced?
