Cannot upload Image file with Dropbox API in C# - uploading corrupt image instead
Hello.
I am trying to upload an image file into my dropbox account with the dropbox api. The image is being uploaded using this code, but it's a corrupt image.
Here is my code:
public async Task UploadToDropbox() { using (var dbx = new DropboxClient(dbToken)) { string srcFilePath = @"~\useruploads\"; string srcFileName = "image1.png"; string srcFile = srcFilePath + srcFileName; string targetFolder = "/uploads"; string targetFileName = "userupload_" + DateTime.Now.ToString("yymmssfff") + ".png"; //byte[] readContent = Encoding.UTF8.GetBytes(srcFile); //uploading corrupt file //byte[] readContent = UTF8Encoding.UTF8.GetBytes(srcFile); //uploading corrupt file //var readContent = System.IO.File.ReadAllBytes(srcFile); //uploading nothing //byte[] readContent = System.IO.File.ReadAllBytes(srcFile); //uploading nothing
using (var mem = new MemoryStream(readContent)) { var updated = await dbx.Files.UploadAsync( targetFolder + "/" + targetFileName, WriteMode.Overwrite.Instance, body: mem); } } }
Thank you for any help.
If you want to upload a local file, you can just do something like this:
using (var file = new FileStream(srcFile, FileMode.Open)) { var updated = await dbx.Files.UploadAsync( targetFolder + "/" + targetFileName, WriteMode.Overwrite.Instance, body: file); }
You'll probably want to add some checking/exception handling to make sure the local file actually exists at that path though.

Unfortunately, with that change, the program isn't going into the using bracket. I tried it out with a try/finally and it seems to just go back to the main method after the "var file = new FileStream(srcFile, FileMode.Open)" line. Any idea why that's happening?
Edit: This was happening because the route was incorrect - your reply worked, thank you!
