我有一个辅助类,它传递一个值数组,然后从我的模型传递给一个新类.如何验证给予此类的所有值是否有效？换句话说,如何在非控制器类中使用ModelState的功能.

从控制器:

public ActionResult PassData()
{
    Customer customer = new Customer();
    string[] data = Monkey.RetrieveData();
    bool isvalid = ModelHelper.CreateCustomer(data, out customer);
}

来自帮手:

public bool CreateCustomer(string[] data)
{
    Customter outCustomer = new Customer();
    //put the data in the outCustomer var
    //??? Check that it's valid

}

我有一个表单发布到MVC的一个动作.我想从操作中的FormCollection中提取所选的下拉列表项.我该怎么做？

我的Html表格:

<% using (Html.BeginForm())
    {%>
    <select name="Content List">
    <% foreach (String name in (ViewData["names"] as IQueryable<String>)) { %>
          <option value="<%= name %>"><%= name%></option>
    <% } %>
    </select>
    <p><input type="submit" value="Save" /></p>
<% } %>

我的行动:

[HttpPost]
public ActionResult Index(FormCollection collection)
{
    //how do I get the selected drop down list value?
    String name = collection.AllKeys.Single();
    return RedirectToAction("Details", name);
}

在使用WCF调用Cisco的AXL SOAP API时,我的CPU使用率很高.我首先使用wsdl生成的类创建服务模型clientbase.我正在使用basichttpbinding和transfermode作为缓冲.执行调用时,CPU最大化,并且CPU配置文件显示96%的CPU时间_TransparentProxyStub_CrossContext@0来自在调用之后调用的clr.dll base.Channel.getPhone(request);.更准确地说,该调用最大化了进程正在运行的CPU核心.

这是来自wsdl generate的客户端创建的片段

[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "4.0.0.0")]
public partial class AXLPortClient : System.ServiceModel.ClientBase<AxlNetClient.AXLPort>, AxlNetClient.AXLPort
{

    public AXLPortClient()
    {
    }

    public AXLPortClient(string endpointConfigurationName) : 
            base(endpointConfigurationName)
    {
    }

    ...

这就是我创建客户端的方式:

public class AxlClientFactory : IAxlClientFactory
{
    private const string AxlEndpointUrlFormat = "https://{0}:8443/axl/";

    public AXLPortClient CreateClient(IUcClientSettings settings)
    {
        ServicePointManager.ServerCertificateValidationCallback = (sender, certificate, chain, errors) => true;
        ServicePointManager.Expect100Continue = false;                      

        var basicHttpBinding = new BasicHttpBinding(BasicHttpSecurityMode.Transport);
        basicHttpBinding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Basic;

        basicHttpBinding.MaxReceivedMessageSize = 20000000;
        basicHttpBinding.MaxBufferSize = 20000000;
        basicHttpBinding.MaxBufferPoolSize = 20000000;

        basicHttpBinding.ReaderQuotas.MaxDepth = …

我正在尝试使用调度计时器测量按键事件之间的经过时间(以毫秒为单位),但是当声明调度计时器的间隔为1毫秒然后建立tick事件时,它不会每隔1毫秒触发一次,而是像10- 100毫秒(猜测).如果此刻度事件未按时触发,如何准确测量时间(以毫秒为单位)？我在Silverlight中这样做,似乎无法访问System.Timers.System.Threading.Timer似乎也发生了同样的情况.

以下是代码的基础知识:

public void StartTimer(object o, RoutedEventArgs sender)
{
    System.Windows.Threading.DispatcherTimer myDispatcherTimer = new  
    System.Windows.Threading.DispatcherTimer();
    myDispatcherTimer.Interval = new TimeSpan(0, 0, 0, 0, 1); // 1 Milliseconds 
    myDispatcherTimer.Tick += new EventHandler(Each_Tick);
    myDispatcherTimer.Start();
}

// A variable to count with.
int i = 0;

public void Each_Tick(object o, EventArgs sender)
{
    i++;
}

public void keypress(object s, EventArgs args)
{
    label1.contents = i.ToString();
    i = 0;
}

有任何想法吗？
