我尝试使用SendGrid在用户注册后向用户发送确认电子邮件，这样一旦他们点击它，他们的帐户就会被确认，他们可以访问该网站。
我已经按照本教程进行了操作：http://www.asp.net/webforms/overview/security/create-a-secure-aspnet-web-forms-app-with-user-registration-email-confirmation-and-password-reset
甚至已经下载了源代码，一旦我注册用户，仍然会出现错误。确切的错误是：mscorlib.dll中出现“Exceptions.InvalidApiRequestException”类型的异常，但未在用户代码中处理
其他信息：错误请求检查Errors以获取API返回的错误列表。
我今天已经工作了8个小时，我真的迷路了。我将展示相关文件，任何帮助或方向将受到高度赞赏！

答案 0 :(得分：1)
在您的web.config文件中，从
更改它add key="emailServiceUserName" value="[mySendGridUsername]"
add key="emailServicePassword" value="[MySendGridPassword]"
到此：
add key="emailServiceUserName" value="mySendGridUsername"
add key="emailServicePassword" value="MySendGridPassword"
删除[] s。问题解决了！ ：）
