Question

我正在尝试执行转移到View的原始SQL语句。我需要有一个模型来保存所有信息，还是只需传递DataTable？这是我的代码。我只是需要帮助将数据提供给视图才能看到它。

namespace DataBaseTest.Controllers
{
    public class HomeController : Controller
    {
        DataTable dtFindResults = new DataTable();
        public ActionResult Index()
        {
            //// define a list of CustomerModel objects
            DataSet tempDS = new DataSet();

            string xSQL = "SELECT PropertyAddress FROM KDOR_vwPropertyGeneral ORDER BY PropertyAddress";
            System.Data.SqlClient.SqlDataAdapter DbCmd = new System.Data.SqlClient.SqlDataAdapter();

            //// populate a list of CustomerModel objects from database
            string MyConnectionString = ConfigurationManager.ConnectionStrings["WLConnection"].ConnectionString;
            System.Data.SqlClient.SqlConnection cnn = new System.Data.SqlClient.SqlConnection(MyConnectionString);
            System.Data.SqlClient.SqlCommand cmd = new System.Data.SqlClient.SqlCommand(xSQL, cnn);
            cmd.CommandTimeout = 30000;
            DbCmd.SelectCommand = cmd;

            DbCmd.Fill(tempDS,"ResultSet");
            dtFindResults = tempDS.Tables["ResultSet"];
            var x = dtFindResults.Rows.Count;
            cnn.Close();

            //// return the list of CustomerModel objects to our View
            return View(dtFindResults);
        }

您需要一个ViewModel。

public class CustomerModel
{
    public string PropertyAddress { get; set; }
}

var vm = new List<CustomerModel>();
foreach (var item in dtFindResults)
{
    vm.Add(new CustomerModel { PropertyAddress = /* value from DataSet */ });
}

return View(vm);

最后，您的DataSet应该来自一个单独的问题，比如Repository。此存储库应返回可以发送到View的ViewModel列表。

DataTable传输到视图
