SendGrid在发送邮件时抛出InvalidApiRequestExceptionSendGrid在发送邮件时抛出InvalidApiRequestException。我正在使用此代码：publicTaskSendEmailAsync(stringemail,stringsubject,stringmessage){//在此处插入您的电子邮件服务以发送电子邮件。varmyMessage=newSendGrid.SendGridMessage();myMessage.AddTo(电子邮件);myMessage.From=newMailAddress("varshney@shobhit.com","Shobhit",System.Text.Encoding.Default);myMessage.Subject=主题;myMessage.Text=消息；myMessage.Html=消息；varcredentials=newNetworkCredential(Options.SendGridUser,Options.SendGridKey);//创建用于发送电子邮件的Web传输。vartransportWeb=newSendGrid.Web(credentials);//发送邮件。if(transportWeb!=null){返回transportWeb.DeliverAsync(myMessage);}else{返回Task.FromResult(0);}}堆垛跟踪是：InvalidApiRequestException:BadRequest检查`Errors`以获取API返回的错误列表。SendGrid.ErrorChecker.CheckForErrors(HttpResponseMessageresponse,Streamstream)SendGrid.ErrorChecker.d__1.MoveNext()---来自p的堆栈跟踪结束抛出异常的上一个位置---System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess（任务任务）System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification（任务任务）d__7.MoveNext()---从抛出异常的先前位置开始的堆栈跟踪结束---System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess（任务任务）System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification（任务任务）System.Runtime.CompilerServices.TaskAwaiter.GetResult()MessageBoard.Controllers.AccountController.d__9.MoveNext()inAccountController.csawait_emailSender.SendEmailAsync(model.Email,"Confirmyouraccount",---从之前位置开始的堆栈跟踪结束抛出异常---System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess（任务任务）System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Tasktask)System.Runtime.CompilerServices.TaskAwaiter`1.GetResult()Microsoft.AspNet.Mvc.Controllers.ControllerActionExecutor.d__8`1.MoveNext()---从抛出异常的先前位置开始的堆栈跟踪结束---System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess（任务任务）System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification（任务任务）System.Runtime.CompilerServices.TaskAwaiter`1.GetResult()Microsoft.AspNet.Mvc.Controllers.ControllerActionInvoker.d__6.MoveNext()---从抛出异常的先前位置开始的堆栈跟踪结束---System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess（任务任务）System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification（任务任务）系统.Runtime.CompilerServices.TaskAwaiter`1.GetResult()Microsoft.AspNet.Mvc.Controllers.FilterActionInvoker.d__53.MoveNext()---来自pre的堆栈跟踪结束抛出异常的vious位置---System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()Microsoft.AspNet.Mvc.Controllers.FilterActionInvoker.d__44.MoveNext()---从抛出异常的先前位置开始的堆栈跟踪结束---System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess（任务任务）System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification（任务任务）System.Runtime.CompilerServices.TaskAwaiter.GetResult()Microsoft.AspNet.Mvc.Infrastructure.MvcRouteHandler.d__6.MoveNext()---从抛出异常的先前位置开始的堆栈跟踪结束---System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess（任务任务）System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification（任务任务）System.Runtime.CompilerServices.TaskAwaiter.GetResult()Microsoft.AspNet.Routing.Template.TemplateRoute.d__27.MoveNext()---上一个位置的堆栈跟踪结束n抛出异常的地方---System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess（任务任务）System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification（任务任务）.RouteCollection.d__9.MoveNext()---从先前抛出异常的位置开始的堆栈跟踪结束---System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess（任务任务）)System.Runtime.CompilerServices.TaskAwaiter.GetResult()Microsoft.AspNet.Builder.RouterMiddleware.d__4.MoveNext()---从先前抛出异常的位置开始的堆栈跟踪结束---System.Runtime.CompilerServices.TaskAwaiter。ThrowForNonSuccess（任务任务）System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification（任务任务）System.Runtime.CompilerServices.TaskAwaiter.GetResult()Microsoft.AspNet.IISPlatformHandler.IISPlatformHandlerMiddleware.d__8.MoveNext()---从上一个抛出异常的位置开始的堆栈跟踪结束---System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Tasktask)System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Tasktask)System.Runtime.CompilerServices.TaskAwaiter.GetResult()Microsoft.AspNet.Diagnostics.Entity.MigrationsEndPointMiddleware.d__5.MoveNext()---异常所在位置的堆栈跟踪结束抛出---System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess（任务任务）System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification（任务任务）System.Runtime.CompilerServices.TaskAwaiter.GetResult().d__6.MoveNext()---从抛出异常的先前位置开始的堆栈跟踪结束---System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()Microsoft.AspNet.Diagnostics.Entity.DatabaseErrorPageMiddleware.d__6.MoveNext()---从先前抛出异常的位置开始的堆栈跟踪结束---System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Tasktask)System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Tasktask)System.Runtime.CompilerServices.TaskAwaiter.GetResult()Microsoft.AspNet.Diagnostics.DeveloperExceptionPageMiddleware.d__7.MoveNext()确保您使用的是SendGridC#库版本6.3那里是.x或更高版本之前的库版本中的错误。对于您的凭据，您使用的是Sendgrid用户名和密码吗？还是您的API密钥？从您的变量名看来，您正在传递一个AP
