To use Microsoft OneDrive API, you must register your application on https://account.live.com/developers/applications to get a clientId like 0000000000000000.
- Install the NuGet package:
Install-Package Meziantou.OneDriveClient.Windows
- Initialize the client:
// Initialize the client
var client = new OneDriveClient();
client.ApplicationId = "000000004418B915";
client.AuthorizationProvider = new AuthorizationCodeProvider(); // Provider to display the login window
// Optional
// Store the refresh token, so the application can re-authenticate automatically when the token expires
client.RefreshTokenHandler = new MemoryRefreshTokenHandler();
client.RefreshTokenHandler = new CredentialManagerRefreshTokenHandler("appname", CredentialPersistence.LocalMachine);
- Use the client:
var item = await Client.CreateDirectoryAsync("sample");
var children = await item.GetChildrenAsync();
var newItem = await item.CreateFileAsync("sample.txt", stream, length: 1000, chunckSize: 100, OnChunkErrorHandler);
var stream = await newItem.DownloadAsync();
