这是我在Form1代码：为什么当试图将视频文件上传到YouTube时，我收到InvalidCredentialsException？

DialogResult result = MessageBox.Show("By clicking 'upload,' " +
"you certify that you own all rights to the content or that you are authorized" +
"by the owner to make the content publicly available on YouTube, and that it otherwise" +
"complies with the YouTube Terms of Service located at http://www.youtube.com/t/terms", "Aggrement",

if (result == DialogResult.Yes)
{
UploadVideo();
}
}
private void button2_Click(object sender, EventArgs e)
{
this.Close();
}
}
}
唯一的例外是上线：
request.Upload(video);
在谷歌发展的网站我创建的应用程序将其称为YouTube上载。 而我在我的c＃应用程序中使用的密钥是客户端ID结尾：apps.googleusercontent.com
但我不确定这是否是正确的关键。 至于我使用我用来登录YouTube的我的gmail电子邮件的用户名。 和密码。
在我的代码中，cmbCat和cmbPrivacy是comboBoxes。
