加载视图与之前的现有数据进行编辑记录在运行update存储过程之前?

我有下面的控制器操作方法。

public int BulkUpdate(List employees) {

       Connection();
       employees = GetAllEmployees().ToList();
        // using reflection, i mean why did i use this ??
        //used it for converting the generic list into datatables.
       DataTable dt = new DataTable(typeof(Employee).Name);
       PropertyInfo[] props = typeof(Employee).GetProperties(BindingFlags.Public | BindingFlags.Instance);
       foreach (var prop in props)
       {
           dt.Columns.Add(prop.Name);
       }

       foreach (var employee in employees)
       {
           var values = new object[props.Length];
           for (int i = 0; i < props.Length; i++)
           {
               values[i] = props[i].GetValue(employee, null);
           }

           dt.Rows.Add(values);
       }
       //
       using (SqlCommand cmd = new SqlCommand("BulkUpdateEmployee", con))
       {
           cmd.CommandType = CommandType.StoredProcedure;
           SqlParameter parameter = cmd.Parameters.AddWithValue("@tblEmployeeType", dt);
           parameter.SqlDbType = SqlDbType.Structured;
           parameter.TypeName = "dbo.EmployeeType";


           con.Open();
           var rowsAffected = cmd.ExecuteNonQuery();
           con.Close();

           return rowsAffected;
       }//using ends here

   }

and this method is being called in main controller:

[AcceptVerbs(HttpVerbs.Get | HttpVerbs.Post)] public JsonResult BulkUpdateOrInsert(List employees) { int rowsAffected=empRepo.BulkUpdate(employees); return Json(rowsAffected, JsonRequestBehavior.AllowGet);

这是视图文件:

@using System.Collections
@model IEnumerable<Employee_Management_System.Models.Employee>

@{
    ViewBag.Title = "BulkUpdateOrInsert";
    Layout = "~/Views/Shared/_Layout.cshtml";

问题是,视图不加载更新记录。我的要求是负载与SQL Server数据库中已有的数据视图。编辑记录使用HTML.EditFor返回通用的列表更新记录- - >将其转换成数据表,并通过数据表存储过程。 (本我)。问题是我不能加载视图更新数据库中的条目。直接存储过程正在加载视图之前执行。

存储过程:

USE EMPLOYEE_Db GO SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO

CREATE PROCEDURE [dbo].[BulkUpdateEmployee] @tblEmployeeType [dbo].[EmployeeType] READONLY AS BEGIN SET NOCOUNT ON; UPDATE dbo.EMPLOYEE SET Employee.Name=et.Name, Employee.City=et.City, Employee.Department=et.Department, Employee.Gender=et.Gender

FROM dbo.EMPLOYEE INNER JOIN @tblEmployeeType AS et ON dbo.EMPLOYEE.EmployeeId=et.EmployeeId

END
