昨晚我想开始一个新项目，但我遇到一个奇怪的错误！如果有人使用过Translation API，请帮忙！
错误提示是： The Application Default Credentials are not available. They are available if running in Google Compute Engine. Otherwise, the environment variable GOOGLE_APPLICATION_CREDENTIALS must be defined pointing to a file defining the credentials. See https://developers.google.com/accounts/docs/application-default-credentials for more information.
我的代码也是Here .
private void Form1_Load(object sender, EventArgs e)
{
TranslationClient cli = TranslationClient.Create();
var word = cli.TranslateText("hello","fa");
MessageBox.Show(word.TranslatedText.ToString());
}
