Mvc 5似乎依赖于Owin,如果你想自己托管或在Mac上运行,那就太棒了.但是我们假设我只想在IIS下运行,就像以前的版本一样,我对Owin提供的东西不感兴趣.默认的"空白"mvc5模板使用owin和其他15个依赖项.我已经尝试逐个删除软件包,但似乎网站不知道如何在不使用Owin的属性的情况下启动.那么,如何在没有Owin的iis下获得ASP.net,mvc 5？

我正在尝试找到一种配置AutoMapper的方法,以通过其源父对象的引用在目标对象中设置属性.下面的代码显示了我想要实现的目标.我正在从数据对象将数据移动到Parent&Child实例中.映射可以正常创建具有正确数据的List集合,但我需要有一个ForEach来分配父实例引用.

public class ParentChildMapper
{
    public void MapData(ParentData parentData)
    {
        Mapper.CreateMap<ParentData, Parent>();
        Mapper.CreateMap<ChildData, Child>();

        //Populates both the Parent & List of Child objects:
        var parent = Mapper.Map<ParentData, Parent>(parentData);

        //Is there a way of doing this in AutoMapper?
        foreach (var child in parent.Children)
        {
            child.Parent = parent;
        }

        //do other stuff with parent
    }
}

public class Parent
{
    public virtual string FamilyName { get; set; }

    public virtual IList<Child> Children { get; set; }
}

public class Child
{

我有一个在IIS7.5中托管的简单WCF服务,使用消息安全性和InstanceContextMode.PerCall通过wsHttp绑定公开

我有一个简单的UI,可以旋转可配置数量的线程,每个线程都调用该服务.

我添加了perfmon计数器ServiceModel4.Instances.无论创建的线程数和调用服务的数量如何,perfmon都会显示该服务最多可创建10个实例.

我的客户端配置如下:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>

  <bindings>
    <wsHttpBinding>

      <binding name="WSHttpBinding_IService3">
        <security mode="Message">
          <transport clientCredentialType="Windows" proxyCredentialType="None"
            realm="" />
          <message clientCredentialType="Windows" negotiateServiceCredential="true"
            algorithmSuite="Default" establishSecurityContext="false" />
        </security>
      </binding>

    </wsHttpBinding>
  </bindings>
  <client>

    <endpoint address="http://localhost/NGCInstancing/Service3.svc/~/Service3.svc"
      binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IService3"
      contract="NGCSecPerCall.IService3" name="WSHttpBinding_IService3">
      <identity>
        <servicePrincipalName value="host/RB-T510" />
      </identity>
    </endpoint>

  </client>
</system.serviceModel>
</configuration>

我的服务配置如下:

<?xml version="1.0"?>
<system.serviceModel>
    <configuration>
        <behaviors>
            <serviceBehaviors>
                <behavior name="SecPerCallBehaviour">
                    <serviceThrottling maxConcurrentCalls="30" maxConcurrentSessions="1000"
                    maxConcurrentInstances="30" />

我知道任何init ...方法都会初始化一个新对象,并且NSString stringWithString会将参数字符串的副本作为新对象.我也理解作为对象的所有者,我可以控制我分配的任何对象的释放/释放.我不明白的是什么时候我会使用stringWithString方法,因为任何以这种方式分配的局部变量都会让它的内存由NSString而不是本地类"拥有".

Kochan的"Objective in Objective C"一书(第1版)使用以下代码(参见第342-344页)来解释initWithString比stringWithString更可取,因为AddressCard类将拥有名称变量contents.另外,使用stringWithString方法重复调用setName版本时,我没有任何错误.TIA!

//header file has appropriate declarations but not included here:
#import "AddressCard.h"

@implementation AddressCard;

-(NSString *) name
{
   return name;
}

//Recommended code:
-(void) setName: (NSString *) theName
{
   [name release]
   name = [[NSString alloc] initWthString: theName];
}

//Incorrect code according to Kochan:
-(void) setName: (NSString *) theName
{
   [name release]
   name = [NSString stringWthString: theName];
}

//rest of class implementation code snipped
@end

在C#中,内存效率更高:选项#1还是选项#2？

public void TestStringBuilder()
{
    //potentially a collection with several hundred items:
    string[] outputStrings = new string[] { "test1", "test2", "test3" };

    //Option #1
    StringBuilder formattedOutput = new StringBuilder();
    foreach (string outputString in outputStrings)
    {
        formattedOutput.Append("prefix ");
        formattedOutput.Append(outputString);
        formattedOutput.Append(" postfix");

        string output = formattedOutput.ToString();
        ExistingOutputMethodThatOnlyTakesAString(output);

        //Clear existing string to make ready for next iteration:
        formattedOutput.Remove(0, output.Length);
    }

    //Option #2
    foreach (string outputString in outputStrings)
    {
        StringBuilder formattedOutputInsideALoop = new StringBuilder();

        formattedOutputInsideALoop.Append("prefix ");
        formattedOutputInsideALoop.Append(outputString);
        formattedOutputInsideALoop.Append(" postfix");

        ExistingOutputMethodThatOnlyTakesAString(
           formattedOutputInsideALoop.ToString());
    }
}

我正在尝试使用此签名为ExpandoObject分配方法(函数):

public List<string> CreateList(string input1, out bool processingStatus)
{
  //method code...
}

我尝试过这样的代码,下面的代码不能编译:

dynamic runtimeListMaker = new ExpandoObject();
runtimeListMaker.CreateList =
     new Func<string, bool, List<string>>(
           (input1, out processingStatus) =>
                {
                     var newList = new List<string>();

                     //processing code...

                     processingStatus = true;
                     return newList;
                });

不幸的是我无法更改CreateList签名,因为它会破坏向后兼容性,因此重写它不是一个选项.我试图通过使用委托解决这个问题,但在运行时,我得到了"无法调用非委托类型"异常.我想这意味着我没有正确分配代表.我需要帮助使语法正确(委托示例也可以).谢谢!!

我需要将一个存在的 DI容器作为参数传递给WCF服务构造函数为了做到这一点,我正在使用IInstanceProvider WCF服务应该托管在自托管中.

public class CustomInstanceProvider : IInstanceProvider, IContractBehavior
{
    private readonly IUnityContainer UnityContainer;

    public CustomInstanceProvider(IUnityContainer unityContainer)
    {
        if (unityContainer == null)
        {
            throw new ArgumentNullException("unityContainer");
        }

        UnityContainer = unityContainer;
    }


    #region Implementation of IInstanceProvider

    public object GetInstance(InstanceContext instanceContext)
    {
        return new Service(UnityContainer);
    }

    public object GetInstance(InstanceContext instanceContext, Message message)
    {
        return this.GetInstance(instanceContext);
    }
    public void ReleaseInstance(InstanceContext instanceContext, object instance)
    {
