控制器端代码：
using System; using System.Collections.Generic; using System.Linq; using System.Web; namespace MvcApplication5注册验证.Models { public class ZhuceBF { private mydboDataContext _Context = new mydboDataContext(); public List<zhuce> Select() { return _Context.zhuce.ToList(); } public zhuce Selectbyid(string id) { var query = _Context.zhuce.Where(p=>p.ID==id); if (query.Count()>0) { return query.First(); } return null; } public bool Selectid(string id) { var query = _Context.zhuce.Where(p => p.ID == id); if (query.Count() > 0) { return true; } return false; } public void Insert(string id,string username,string userpwd) { if (username == "" || username == " ") { } else { zhuce data = new zhuce(); data.ID = id; data.Username = username; data.Userpwd = userpwd; _Context.zhuce.InsertOnSubmit(data); _Context.SubmitChanges(); } } public void Update(string id, string username, string userpwd) { var query = _Context.zhuce.Where(p=>p.ID==id); if (query.Count()>0) { zhuce data = query.First(); data.ID = id; data.Username = username; data.Userpwd = userpwd; } _Context.SubmitChanges(); } public void Delete(string id) { var query = _Context.zhuce.Where(p=>p.ID==id); if (query.Count()>0) { zhuce data = query.First(); _Context.zhuce.DeleteOnSubmit(data); _Context.SubmitChanges(); } } } }
视图端代码：

Model层方法代码：
using System; using System.Collections.Generic; using System.Linq; using System.Web; namespace MvcApplication5注册验证.Models { public class ZhuceBF { private mydboDataContext _Context = new mydboDataContext(); public List<zhuce> Select() { return _Context.zhuce.ToList(); } public zhuce Selectbyid(string id) { var query = _Context.zhuce.Where(p=>p.ID==id); if (query.Count()>0) { return query.First(); } return null; } public bool Selectid(string id) { var query = _Context.zhuce.Where(p => p.ID == id); if (query.Count() > 0) { return true; } return false; } public void Insert(string id,string username,string userpwd) { if (username == "" || username == " ") { } else { zhuce data = new zhuce(); data.ID = id; data.Username = username; data.Userpwd = userpwd; _Context.zhuce.InsertOnSubmit(data); _Context.SubmitChanges(); } } public void Update(string id, string username, string userpwd) { var query = _Context.zhuce.Where(p=>p.ID==id); if (query.Count()>0) { zhuce data = query.First(); data.ID = id; data.Username = username; data.Userpwd = userpwd; } _Context.SubmitChanges(); } public void Delete(string id) { var query = _Context.zhuce.Where(p=>p.ID==id); if (query.Count()>0) { zhuce data = query.First(); _Context.zhuce.DeleteOnSubmit(data); _Context.SubmitChanges(); } } } }
