上传文件Dropbox使用VB.NET

Question

    Dim _client = New DropNetClient("xxxxxxxxxxxxxxxxx", "xxxxxxxxxxxxxxxxx")
    Dim arq As String = "d:\teste.txt"
    Dim filebytes = New FileInfo(arq)
    Dim content As Byte() = _client.GetFileContentFromFS(filebytes)
    Dim result = _client.UploadFile("/", arq, content) '<<<<erro: "use the "new" keyword to create an objtect instance
    MsgBox(result.ToString())

错误：“使用”new“关键字来创建对象实例!!!

谢谢。
