小编Rog*_*Far的帖子

在VS2012上运行单元测试最近非常慢,当我运行它们需要大约12秒才开始实际测试.

当我调试它时,在我遇到第一个断点之前是同一个故事.

我连接了进程监视器然后我发现了这个:

CreateFile \\WORKSTATION*\MAILSLOT\NET\NETLOGON SUCCESS

WriteFile \\WORKSTATION*\MAILSLOT\NET\NETLOGON BAD NETWORK PATH

之后它会保持9秒安静.

CloseFile \\WORKSTATION*\MAILSLOT\NET\NETLOGON SUCCESS

这到底是怎么回事？我根本找不到MAILSLOT和Visual Studio之间的任何关系,但它现在持续了大约2周.

我在我的模式中有这个:

[Required(AllowEmptyStrings = false, ErrorMessageResourceType = typeof(Registration), ErrorMessageResourceName = "NameRequired")]
[MinLength(3, ErrorMessageResourceType = typeof(Registration), ErrorMessageResourceName = "NameTooShort")]
public String Name { get; set; }

最终结果如下:

    <div class="editor-label">
        <label for="Name">Name</label>
    </div>
    <div class="editor-field">
        <input class="text-box single-line" data-val="true" data-val-required="Name is required" id="Name" name="Name" type="text" value="" />
        <span class="field-validation-valid" data-valmsg-for="Name" data-valmsg-replace="true"></span>
    </div>

为什么MinLength会被编译器忽略？我怎么能"开启"？

我不是MVVM模式的常规,这基本上是我第一次玩它.

我以前做的("普通"WPF)是用业务层创建我的视图,也许是数据层(通常包含我的服务或实体框架创建的实体).

现在经过一些玩弄我从MVVM Light创建了一个标准模板,并做到了这一点:

定位:

public class ViewModelLocator
{
    static ViewModelLocator()
    {
        ServiceLocator.SetLocatorProvider(() => SimpleIoc.Default);

        if (ViewModelBase.IsInDesignModeStatic)
        {
            SimpleIoc.Default.Register<IUserService, DesignUserService>();
        }
        else
        {
            SimpleIoc.Default.Register<IUserService, IUserService>();
        }

        SimpleIoc.Default.Register<LoginViewModel>();
    }

    public LoginViewModel Login
    {
        get
        {
            return ServiceLocator.Current.GetInstance<LoginViewModel>();
        }
    }
}

登录ViewModel:

public class LoginViewModel : ViewModelBase
{
    private readonly IUserService _userService;

    public RelayCommand<Object> LoginCommand
    {
        get
        {
            return new RelayCommand<Object>(Login);
        }
    }

    private string _userName;
    public String UserName
    {
        get { return _userName; }
        set
        {
            if (value == _userName)
                return; …

如何newsequentialid()在PK列中使用默认值？

我有这个注释:

[Key, DatabaseGenerated(DatabaseGeneratedOption.Identity)]

但是这会产生随机的guid,我希望有顺序的guid.

我可以手动将数据库设置newsequentialid()为默认值,但是没有更好的选择吗？或者EF团队忘记了这个选项？

我有一个应用程序,它不从本地磁盘读取任何文件或不尝试写任何东西.

它在本地文件系统上运行完美,但它需要在几百个工作站上运行,所以我将它放在Win2003服务器上的共享上.

但是当我尝试在UNC的XP工作站上启动时:

system.io.fileloadexception

这可能是什么问题？

我有2个简单的类:

public class Setting
{
    [Key, DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public Guid SettingId { get; set; }

    [Required]
    public String Name { get; set; }

    public String Value { get; set; }

    [Required]
    public SettingCategory SettingCategory { get; set; }
}

public class SettingCategory
{
    [Key, DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public Guid SettingCategoryId { get; set; }

    [Required]
    public String Value { get; set; }

    public ICollection<Setting> Settings { get; set; }
}

当我SettingCategory从数据库中检索a时,集合Settings始终为null.

当我做它virtual然后会说:The ObjectContext instance has been disposed and …

我们在该公司有一个运行5/6开发人员的ASP.NET项目.所有Visual Studio 2017和IIS Express上的调试,没有疯狂的设置或任何使其运行的东西.

1位同事无法让它工作,他总是得到以下例外:

几个月前我们遇到了这个问题,然后出于挫败感重新安装了PC,问题就消失了.他没有发展几周,今天又出现了问题.

我搜索了很长时间,但这是一个普遍的错误,我无法真正解决这个问题.

当我运行融合日志查看器时,我看到以下结果:

我通过取消选中publish属性来禁用Visual Studio中的更新检查The application should check for updates。

我的应用程序检查更新，用户必须选择拒绝更新。

问题是，当用户跳过更新时，下次他启动应用程序时，将再次显示默认的ClickOnce更新屏幕。

如何确保它永远不会显示默认的ClickOnce更新对话框？

我的更新代码：

private void CheckForUpdates()
{
    if (!ApplicationDeployment.IsNetworkDeployed)
    {
        return;
    }

    var currentDeployment = ApplicationDeployment.CurrentDeployment;

    UpdateCheckInfo info;
    try
    {
        info = currentDeployment.CheckForDetailedUpdate();
    }
    catch (Exception e)
    {
        return;
    }

    if (!info.UpdateAvailable)
    {
        return;
    }

    var changelogDialog = new Changelog();
    if (changelogDialog.ShowDialog() != true)
    {
        return;
    }

    currentDeployment.Update();

    Exit();
}

这是我的清单：

我正在尝试使用Android与KSOAP2一起发布到我自己的测试肥皂服务器(C#).

现在我有来自SOAP服务器的规范,它期望:

POST /SharingpointCheckBarcode.asmx HTTP/1.1
Host: awc.test.trin-it.nl
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://tempuri.org/checkBarcode"

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"     xmlns:xsd="http://www.w3.org/2001/XMLSchema"     xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Header>
    <AuthHeader xmlns="http://tempuri.org/">
      <username>string</username>
      <password>string</password>
    </AuthHeader>
  </soap:Header>
  <soap:Body>
    <checkBarcode xmlns="http://tempuri.org/">
      <barcode>string</barcode>
    </checkBarcode>
  </soap:Body>
</soap:Envelope>  

但Android KSOAP2发出的是:

<?xml version="1.0" encoding="utf-8"?>
    <v:Envelope xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns:d="http://www.w3.org/2001/XMLSchema" xmlns:c="http://schemas.xmlsoap.org/soap/encoding/" xmlns:v="http://schemas.xmlsoap.org/soap/envelope/">
        <v:Header />
        <v:Body>
            <checkBarcode xmlns="http://tempuri.org" id="o0" c:root="1">
                <username i:type="d:string">test</username>

            </checkBarcode>
        </v:Body>
    </v:Envelope>

使用此代码:

    try {
    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

        request.addProperty("username", "test");
        request.addProperty("password", "test");
        request.addProperty("barcode", "2620813000301");

        SoapSerializationEnvelope envelope = new …

我试图用Ajax将它提交给MVC3控制器:

    var params = {
        'productId': productId,
        'list': []
    };

    $.each($('.specificationId'), function () {
        var specId = $(this).attr('id').replace('specification_', '');

        var specification = {
            specificationId: specId,
            articleId: $('#articleid_' + specId).attr('value'),
            price: $('#price_' + specId).attr('value'),
            stock: $('#stock_' + specId).attr('value'),
            stockCount: $('#stockcount_' + specId).attr('value'),
            weight: $('#weight_' + specId).attr('value'),
            visible: $('#visible_' + specId).attr('checked')
        };

        params.list.add(specification);
    });

    console.log(params);
    //all values are parsed fine here, shows an array with json objects

    $.ajax({
        type: "POST",
        url: "/Admin/Product/Save/",
        data: params,
        success: function () { alert('done'); }
    });

现在这必须像这样去控制器: …
