内容导读

1 概述
本篇文章主要从操作上简要分析Controller<=>View之间相互传值，关于页面之间传值，如果感兴趣，可参考我另外一篇文章ASP.NET 页面之间传值的几种方式 。
Controller=》View：Model,ViewBag,ViewData,TempData,ViewBag=>ViewData,ViewData=>ViewBag,ViewModel,JqGrid,AJAX+第三方插件等；
View=》Controller：QueryString,Form,FormCollection,Ajax,自定义模型绑定等；
2 Controller向View传递数据
2.1 Model传递数据
(1)DB表：
(2)Model
1 public class CustomerInfo
2 {
3 public string EmployeeID { get; set; }
4 public string EmployeeName { get; set; }
5 public string EmployeeMajor { get; set; }
6 public string EmployeeDepartment { get; set; }
7 public string EmployeeTel { get; set; }
8 public string EmployeeEmail { get; set; }
9 public string EmployeeJiGuan { get; set; }
10 public string EmployeeAddress { get; set; }
11 public string EmployeePosition { get; set; }
12 public string EmployeeBirthday { get; set; }
13 }
(3)Controller
a.控制器action
public ActionResult ModelDataToView()
{
//定义集合
List<CustomerInfo> ltPI = new List<CustomerInfo>();
DataTable dt = GetCustomerInfoToDataTable();
for (int i = 0; i < dt.Rows.Count; i++)
{
CustomerInfo custInfo = new CustomerInfo();
custInfo.EmployeeID = dt.Rows[i]["EmployeeID"].ToString();
custInfo.EmployeeName = dt.Rows[i]["EmployeeName"].ToString();
custInfo.EmployeeMajor = dt.Rows[i]["EmployeeMajor"].ToString();
custInfo.EmployeeDepartment = dt.Rows[i]["EmployeeDepartment"].ToString();
custInfo.EmployeeTel = dt.Rows[i]["EmployeeTel"].ToString();
custInfo.EmployeeEmail = dt.Rows[i]["EmployeeEmail"].ToString();
custInfo.EmployeeJiGuan = dt.Rows[i]["EmployeeJiGuan"].ToString();
custInfo.EmployeeAddress = dt.Rows[i]["EmployeeAddress"].ToString();
custInfo.EmployeePosition = dt.Rows[i]["EmployeePosition"].ToString();
custInfo.EmployeeBirthday = dt.Rows[i]["EmployeeBirthday"].ToString();
ltPI.Add(custInfo);
}
return View("Index",ltPI);
}
b.ADO.NET 获取CustomerInfo数据
1 //获取用户实体
2 public DataTable GetCustomerInfoToDataTable()
3 {
4 //连接字符串
5 string conStr = ConfigurationManager.ConnectionStrings["conStr"].ConnectionString;
6 string strSql = @"SELECT * FROM EmployeeInfo";
7 using (SqlConnection conn = new SqlConnection(conStr))
8 {
9 conn.Open();
10 SqlCommand cmd = new SqlCommand(strSql, conn);
11 cmd.ExecuteNonQuery();
12 SqlDataAdapter sda = new SqlDataAdapter(strSql, conn);
13 DataSet ds = new DataSet();
14 sda.Fill(ds,"CustomerInfo");
15 return ds.Tables["CustomerInfo"];
16 }
17 }
(4)View

2 Layout = null;

关于第三方插件，类型比较多，如Bootstrap-table等，希望广大读者朋友去研究。JqGrid，其功能很强大，在本篇文章中，仅仅是提及，下篇文章将重点分析JqGrid,与广大读者朋友分享。
2.6 ViewBag=》ViewData
2.7 ViewData=》ViewBag
