entity framework 5 更新指定字段

dbSet.Attach(good);            var stateEntry = ((IObjectContextAdapter)context).ObjectContext.            ObjectStateManager.GetObjectStateEntry(good);            stateEntry.SetModified();            stateEntry.SetModifiedProperty("Title");            stateEntry.SetModifiedProperty("UpdateDate");            context.SaveChanges();

  如果出现

对一个或多个实体的验证失败。有关详细信息,请参见“EntityValidationErrors”属性

还需在SaveChanges前先关闭验证实体有效性(ValidateOnSaveEnabled)这个开关

最终代码
dbSet.Attach(good);            var stateEntry = ((IObjectContextAdapter)context).ObjectContext.            ObjectStateManager.GetObjectStateEntry(good);            stateEntry.SetModified();            stateEntry.SetModifiedProperty("Title");            stateEntry.SetModifiedProperty("UpdateDate");            context.Configuration.ValidateOnSaveEnabled = false;            context.SaveChanges();            context.Configuration.ValidateOnSaveEnabled = true;
