使用dropnet上传大文件

Question

I'm using dropnet to upload files to the dropbox. Until then everything is working well, but only for small files on it. The following code I'm using to send:

private void btnEnviar_Click(object sender, EventArgs e)
{
    var _client = new DropNetClient("xxxxxxxxxxxxx", "xxxxxxxxxxxxxx", "xxxxxxxxxxxxx", "xxxxxxxxxxxxxxxx");
    _client.UseSandbox = true;

    string arq = "";
    string path = "";
    foreach (DataGridViewRow dr in dgvArquivos.Rows)
    {
        if (dr.Cells[0].Value != null)
        {
            arq = dr.Cells[3].Value.ToString();
            path = "//server/documentos/Scanner_/exames";
            try
            {

                var filebytes = new FileInfo(@path+"/"+arq);
                byte[] content = _client.GetFileContentFromFS(filebytes);
                var result=_client.UploadFile("/exames",arq,content);
                this.lblMsg.Text = result.ToString();
                dr.Cells[4].Value = "17/12/2014";
            }
            catch (Exception ex)
            {

                this.lblMsg.Text= ex.Message.ToString();
            }
        }

    }
}

How do I send files larger on average than 50mb?

Depending on the actual error you're getting the answer might change. ie, if its out of memory or a HTTP error from the API.

DropNet does have support for chunked uploading of files which you might want to have a look at. Documentation for it is a little lacking at the moment but looking at the source should tell you how to use it. https://github.com/DropNet/DropNet/blob/master/DropNet/Client/Files.Sync.cs#L224

Making a call to StartChunkedUpload to start the upload, call AppendChunkedUpload to append more bytes to the upload then call CommitChunkedUpload to complete the upload. Use this with a streaming read of the file if possible to reduce the memory usage.
