Elmah和DbEntityValidationException
我已经使用Elmah和EF4.1 Code First建立了一个项目。
该项目抛出“ 0”，但是Elmah没有提供足够的详细信息来确定验证失败的原因。所有记录的是：
System.Data.Entity.Validation.DbEntityValidationException: Validation failed for one or more entities. See \'EntityValidationErrors\' property for more details.

List<IUserFeedback> errors = new List<IUserFeedback>(); try { _dbContext.SaveChanges(); Updated(this, HasUnsavedChanges); } catch (DbEntityValidationException ex) { foreach (var x in ex.EntityValidationErrors) { foreach (var y in x.ValidationErrors) { if (!String.IsNullOrWhiteSpace(y.PropertyName)) errors.Add(new UserFeedback() { FeedbackFlags = TypeOfUserFeedbackFlags.Error, Message = String.Format(\"Unable to save {0} due to an issue with its \\\"{1}\\\" value. The error returned was \\\"{2}\\\"\",x.Entry.Entity, y.PropertyName, y.ErrorMessage) }); else errors.Add(new UserFeedback() { FeedbackFlags = TypeOfUserFeedbackFlags.Error, Message = String.Format(\"Unable to save {0} due to the error \\\"{1}\\\"\", x.Entry, y.ErrorMessage) }); } } } return errors;
