谁能帮助我如何在 ASP.net MVC3 (MS Visual Studio 2010) 查看页面上使用 UniDynArray？
我设法将引用（U2.Data.Client）添加到项目中，并且可以在控制器中使用它，但不能在视图页面中使用。
使用 UniDynArray 的原因是，我想将动态数组从 Controller 传递给 View 并返回给控制器。这样我就不必将每个字段都设置为 VIEWDATA 以便在 View 中使用。

我想解释一下如何通过以下方式将 UniDynArray 从 Controller 传递给 MVC View：
- MVVM 模式（原始 UniDynArray）
- ViewBag 模式（原始 UniDynArray）
- MVVM 模式（将 UniDynArray、UniDynArray 展平为 .NET 对象数据表）
- MVVM 模式（将 UniDynArray、UniDynArray 展平为 POCO 对象）
在这篇文章中，我将回答 MVVM Pattern (Raw UniDynArray)。稍后我将介绍休息。
创建 ASP.NET MVC3 项目

添加控制器
创建视图
打开“CustomerViewModel.cs”文件并粘贴以下代码
命名空间 Test_MvcApplication.Models {
public class CustomerViewModel
{
public Customer MyCustomer { get; set; }
public CustomerViewModel(Customer pCustomer)
{
MyCustomer = pCustomer;
}
}
public class Customer
{
private UniDynArray myVar;
public UniDynArray MyUniDynArray
{
get
{
U2ConnectionStringBuilder conn_str = new U2ConnectionStringBuilder();
conn_str.UserID = "user";
conn_str.Password = "pass";
conn_str.Server = "localhost";
conn_str.Database = "HS.SALES";
conn_str.ServerType = "UNIVERSE";
conn_str.AccessMode = "Native"; // FOR UO
conn_str.RpcServiceType = "uvcs"; // FOR UO
conn_str.Pooling = false;
string s = conn_str.ToString();
U2Connection con = new U2Connection();
con.ConnectionString = s;
con.Open();
Console.WriteLine("Connected.........................");
// get RECID
UniSession us1 = con.UniSession;
UniSelectList sl = us1.CreateUniSelectList(2);
// Select UniFile
UniFile fl = us1.CreateUniFile("CUSTOMER");
fl.RecordID = "2";
myVar = fl.Read();
return myVar;
}
set
{
myVar = value;
}
}
}
}
打开“MyUniDynArrayController.cs”并粘贴以下代码。当您注意到您正在将对象传递给视图并且该对象具有 UniDynArray
命名空间 Test_MvcApplication.Controllers { public class MyUniDynArrayController : Controller { // // GET: /MyUniDynArray/
public ActionResult Index()
{
Customer c = new Customer();
UniDynArray r = c.MyUniDynArray;
var l = new CustomerViewModel(c);
return View(l);
}
}
}
打开“MyUniDynArray\ Index.cshtml”并粘贴以下代码。@Model 包含 ViewModel 对象 (UniDynArray)
@{ ViewBag.Title = "索引"; }
MyUniDynArray
===================
@Model.MyCustomer.MyUniDynArray
打开“Shared\Layout.cshtml”文件并添加以下行
<nav>
<ul id="menu">
<li>@Html.ActionLink("MyUniDynArray", "Index", "MyUniDynArray")</li>
<li>@Html.ActionLink("Home", "Index", "Home")</li>
<li>@Html.ActionLink("About", "About", "Home")</li>
</ul>
</nav>
运行应用程序并按“MyUniDynArray”。您将在视图中看到 UniDynArray。我不确定您将如何将 UniDynArray 与 HTML5/Razor 控件绑定。这就是为什么我建议你扁平化 UniDynArray。

在这篇文章中，我想描述“MVVM Pattern (flatten UniDynArray, UniDynArray to .NET Object Object)”。

打开模型文件 (Models\CustomerViewModel2.cs) 并粘贴代码
命名空间 Test_MvcApplication.Models {
public class Customer2
{
public int ID { get; set; }
public string Name { get; set; }
public DateTime HireDate { get; set; }
}
public class Customer2Repository
{
private List<Customer2> m_custList = new List<Customer2>();
public List<Customer2> CustomerList
{
get
{
U2ConnectionStringBuilder l = new U2ConnectionStringBuilder();
l.Server = "localhost";
l.UserID = "user";
l.Password = "pass";
l.Database = "HS.SALES";
l.ServerType = "universe";
string lconnstr = l.ToString();
U2Connection c = new U2Connection();
c.ConnectionString = lconnstr;
c.Open();
U2Command command = c.CreateCommand();
command.CommandText = "CALL MV_TO_DATASET_SELECT_SUBROUTINE(?,?)"; // UniVerse subroutine
command.CommandType = CommandType.StoredProcedure;
U2Parameter p1 = new U2Parameter();
p1.Direction = ParameterDirection.InputOutput;
p1.Value = "";
p1.ParameterName = "@arg1";
U2Parameter p2 = new U2Parameter();
p2.Direction = ParameterDirection.InputOutput;
p2.Value = "";
p2.ParameterName = "@arg2";
command.Parameters.Add(p1);
command.Parameters.Add(p2);
command.ExecuteNonQuery();
string lRetValue = (string)command.Parameters[1].Value;
//command.Parameters[1].MV_To_POCO<int>();
m_custList = command.Parameters[1].MV_To_POCO<Customer2>();
return m_custList;
}
set
{
m_custList = value;
}
}
}
public class CustomerViewModel2
{
public Customer2 MyCustomer2 { get; set; }
public List<Customer2> CustomerList { get; set; }
public CustomerViewModel2(Customer2 pCustomer)
{
MyCustomer2 = pCustomer;
}
public CustomerViewModel2(List<Customer2> pCustomerList)
{
CustomerList = pCustomerList;
}
}
}
打开控制器文件 (Controllers\MyUniDynArray2Controller.cs)
命名空间 Test_MvcApplication.Controllers { public class MyUniDynArray2Controller : Controller { // // GET: /MyUniDynArrayController2/
public ActionResult Index()
{
Customer2Repository lvar = new Customer2Repository();
List<Customer2> lCustomer2List = lvar.CustomerList;
var l = new CustomerViewModel2(lCustomer2List);
return View(l);
}
}
}
打开视图文件 (Views\MyUniDynArray2\Index.cshtml)
@{
ViewBag.Title = "Index";
}
<h2>Index</h2>
<table border="1">
<tr>
<td>ID</td>
<td>Name</td>
<td>HireDate</td>
</tr>
@foreach (var myItem in Model.CustomerList)
{
<tr>
<td>@myItem.ID</td>
<td>@myItem.Name</td>
<td>@myItem.HireDate</td>
</tr>
}
</table>
打开“Shared\Layout.cshtml”文件并添加以下行
<nav>
<ul id="menu">
<li>@Html.ActionLink("MyUniDynArray2", "Index", "MyUniDynArray2")</li>
<li>@Html.ActionLink("MyUniDynArray", "Index", "MyUniDynArray")</li>
<li>@Html.ActionLink("Home", "Index", "Home")</li>
<li>@Html.ActionLink("About", "About", "Home")</li>
</ul>
</nav>
运行应用程序并按“MyUniDynArray2”。您将看到 Flatten UniDynArray。基本上 UniDynArray 成为 .NET 对象的数组（列表）
使用的宇宙子程序
SUBROUTINE MV_TO_DATASET_SELECT_SUBROUTINE(ARG_INPUT,ARG_OUTPUT)
x = ARG_INPUT
ARG_OUTPUT = "100":@VM:"101":@VM:"102":@VM:"103":@FM:"Nancy":@VM:"Andrew":@VM:"Janet":@VM :"玛格丽特":@FM:"01/06/1991":@VM:"06/07/1996":@VM:"11/08/1999":@VM:"12/10/2001"
