我有一些代码可以保存数据，创建数据和加载数据库。
但是，有没有办法优化此代码？比如for循环只是为了从列表中为模型赋值？我觉得这很麻烦，因为我有更多的条目要保存并在以后添加。
创建我的表，如果它们不存在：
using (IRISInSiteLiveEntities DB = new IRISInSiteLiveEntities()) { ProjectDetails_Deployment projectdetails_Deployment = new ProjectDetails_Deployment(); ProjectDetails_DeskTopReview projectdetails_DeskTopReview = new ProjectDetails_DeskTopReview(); ProjectDetails_Handover projectdetails_Handover = new ProjectDetails_Handover(); ProjectDetails_SiteDetails projectdetails_SiteDetails = new ProjectDetails_SiteDetails(); ProjectDetails_Survey projectdetails_Survey = new ProjectDetails_Survey(); //Deployment projectdetails_Deployment.ProjectID = id; projectdetails_Deployment.SiteID = siteid; projectdetails_Deployment.Visit = visit; projectdetails_Deployment.SiteName = sitename; //Handover projectdetails_Handover.ProjectID = id; projectdetails_Handover.SiteID = siteid; projectdetails_Handover.Visit = visit; projectdetails_Handover.SiteName = sitename; //DesktopReview projectdetails_DeskTopReview.ProjectID = id; projectdetails_DeskTopReview.SiteID = siteid; projectdetails_DeskTopReview.Visit = visit; projectdetails_DeskTopReview.SiteName = sitename; //SiteDetails projectdetails_SiteDetails.ProjectID = id; projectdetails_SiteDetails.SiteID = siteid; projectdetails_SiteDetails.Visit = visit; projectdetails_SiteDetails.SiteName = sitename; //Survey projectdetails_Survey.ProjectID = id; projectdetails_Survey.SiteID = siteid; projectdetails_Survey.Visit = visit; projectdetails_Survey.SiteName = sitename; DB.ProjectDetails_Deployment.Add(projectdetails_Deployment); DB.SaveChanges(); DB.ProjectDetails_Handover.Add(projectdetails_Handover); DB.SaveChanges(); DB.ProjectDetails_SiteDetails.Add(projectdetails_SiteDetails); DB.SaveChanges(); DB.ProjectDetails_DeskTopReview.Add(projectdetails_DeskTopReview); DB.SaveChanges(); DB.ProjectDetails_Survey.Add(projectdetails_Survey); DB.SaveChanges(); }
将数据保存到我的数据库（使用循环而不是分配每个？）
