小编kma*_*zek的帖子

我正在尝试HttpContextBase在我的SignalR集线器中注入一个:

public class EventHub : Hub, IDisconnect
{
    private readonly HttpContextBase _httpContextBase;

    public EventHub(HttpContextBase httpContextBase)
    {
        _httpContextBase = httpContextBase;
    }

    [...]
}

注册码如下所示:

private static void InitAutofac()
{
    var builder = new ContainerBuilder();

    var assembly = typeof (MvcApplication).Assembly;

    builder.RegisterControllers(assembly).PropertiesAutowired();
    builder.RegisterModule(new AutofacWebTypesModule());
    builder.RegisterFilterProvider();

    builder.RegisterAssemblyTypes(assembly)
        .Where(InterfaceBasedInjectedClasses())
        .AsImplementedInterfaces()
        .InstancePerLifetimeScope();

    builder.RegisterAssemblyTypes(assembly)
        .Where(InterfaceLessInjectedClasses())
        .InstancePerLifetimeScope();

    builder.RegisterType<SurvivalContainer>().InstancePerLifetimeScope();

    builder.RegisterType<EventHub>().InstancePerLifetimeScope();

    var container = builder.Build();

    DependencyResolver.SetResolver(new AutofacDependencyResolver(container));


    GlobalHost.DependencyResolver = new SignalR.Autofac.AutofacDependencyResolver(container);

    RouteTable.Routes.MapHubs();
}

而我得到的错误是:

[DependencyResolutionException:从请求实例的作用域中看不到具有匹配'httpRequest'的标记的作用域.这通常表示注册为每HTTP请求的组件正被SingleInstance()组件(或类似场景)重新请求.在Web集成下,始终从DependencyResolver.Current或ILifetimeScopeProvider.RequestLifetime请求依赖项,从不从容器本身请求]

我正在尝试使用自定义字体TextView.该TextView文本设置与textView1.setText(Html.fromHtml(htmlText));

html包含粗体和斜体

现在.我购买了自定义字体.该字体带有3个不同的文件(ttf).一个用于常规,一个用粗体和斜体.

如何将这三个字体文件应用于textview？

我想要一个文本框在我点击它时显示变量的值(迭代次数为1到100),我不知道我在做什么错误:

当我运行项目时,文本框中不显示任何内容.

在文本框中显示变量的最佳方法是什么？

我是C#Wpf的初学者,我想通过编程制作一个几乎没有paragrah的流程文档.问题是pagraph之间有一个很大的空间,我想把它调整到最小.

我通过使用Xml语句找到了一个解决方案,但我希望通过编程来实现:

<FlowDocument>
  <FlowDocument.Resources>
    <!-- This style is used to set the margins for all paragraphs in the FlowDocument to 0. -->
    <Style TargetType="{x:Type Paragraph}">
      <Setter Property="Margin" Value="0"/>
    </Style>
  </FlowDocument.Resources>

  <Paragraph>
    Spacing between paragraphs is caused by margins set on the paragraphs.  Two adjacent margins
    will "collapse" to the larger of the two margin widths, rather than doubling up.
  </Paragraph>

  <Paragraph>
    To eliminate extra spacing between two paragraphs, just set the paragraph margins to 0.
  </Paragraph>
</FlowDocument>

我该怎么做 ？.

thanx对你有所帮助.

我决定继续快速角落优化并坚持 _mm_movemask_epi8SSE指令.如何通过uint8x16_t输入为ARM Neon重写它？

我有以下代码,我正在尝试调试

int ll(ref float[,] _lv) {
  object[] results = new object[20];

  results = func_v1(11, _lv);

}

打破观察变量'结果'显示如下所示

results {object[11]}
 + [0] {float[1,1]}
 + [1] {double[1,1]}
 + [2] {float[48,1]}
   ...
   ...
 + [10] {float[1,1]}

而且我无法输入强制转换来获取它的值

float f = (float)results[0]; 抛出无效的强制转换异常.

请帮助我理解这个对象数组究竟是什么以及如何从中获取值.

问候.AK

现在,在SDK SDK API级别16中不推荐使用类的setBackgroundDrawable()方法View.

新方法setBackground()当然只能在API 16中使用.

如果我希望我的应用程序与以前的API级别兼容,我该如何解决它？(至少API 14)

目标是消除任何警告,@SupressWarnings不是我的解决方案.

我有这个字典和元组在SetValue()中设置如下: -

var myDict = new Dictionary<string, Tuple<string, string>>();

private void SetValue() 
{
  var myTuple1= Tuple.Create("ABC", "123");
  var myTuple2= Tuple.Create("DEF", "456");
  myDict.Add("One", myTuple1)
  myDict.Add("Two", myTuple2)
}

我试图在GetValue()中检索元组,如下所示: -

private void GetValue()
{
  var myTuple = new Tuple<string, string>("",""); //Is this correct way to initialize   tuple
  if (myDict.TryGetValue(sdsId, out myTuple))
  {
    var x = myTuple.Item1;
    var y = myTuple.Item2;
   }
}

我的问题是,这是否是从字典中检索元组时初始化元组的正确方法？有更好的代码吗？

 var myTuple = new Tuple<string, string>("","");

我正在尝试将 .NET 类序列化为 JSON，其中包含一个属性，该属性是泛型类型的泛型列表。

我的通用类型定义如下：

public interface IFoo {}

public class Foo<T>: IFoo
{
  public string Name {get; set;}
  public string ValueType {get; set;}
  public T Value {get; set:}

    public Foo(string name, T value)
    {
      Name = name;
      Value = value;
      ValueType = typeof(T).ToString();
    }
}

然后，如下：

public class Fum
{
  public string FumName {get; set;}
  public list<IFoo> Foos {get; set;}
}

我创建实例如下：

myFum = new Fum();
myFum.FumName = "myFum";
myFum.Foos.Add(new Foo<int>("intFoo", 2);
myFum.Foos.Add(new Foo<bool>("boolFoo", true);
myFum.Foos.Add(new Foo<string>("stringFoo", "I'm a …
