In a verbatim string literal (@"foo") in C#, backslashes aren't treated as escapes, so doing " to get a double quote doesn't work. Is there any way to get a double quote in a verbatim string literal? This understandably doesn't work: string foo = @"this "word" is escaped"; Use a duplicated double quote. @"this ""word"" is escaped"; outputs: this "word" is escaped
在C＃中的逐字字符串字面值（@“foo”）中，反斜杠不被视为转义字符，因此“”以获得双引号不起作用。是否有任何方法可以在逐字字符串文字中获得双引号？ 这可以理解不起作用： string foo = @"this "word" is escaped"; 使用重复的双引号。 @"this ""word"" is escaped"; 输出： this "word" is escaped 使用双引号。 string foo = @"this ""word"" is escaped"; 为了添加更多信息，您的示例将不带@符号（它可以防止用转义

Shortly speaking I am trying to link Castle Windsor container with Unity container. Let me explain the context: I have a project in which for very long time it used castle windsor. A few days ago, I got a bunch of dll's that I must consume / use from my old project. Those DLL's use Unity Container as their injection mechanism. I also have access to interfaces / implementations that
简而言之，我尝试将Castle Windsor容器与Unity容器连接起来。 让我解释一下上下文： 我有一个项目，在很长一段时间里它使用了温莎城堡。 几天前，我收到了一堆我必须从旧项目中使用/使用的dll。 那些DLL使用Unity Container作为注入机制。 我也可以访问在这些DLL中找到的接口/实现，但我不会尝试实例化手动实现，但我只是希望将Unity容器与当前的城堡windsor容器链接起来。 我怎么能做到这一点？ 所以如果我有： public

I have a requirement in which i have to use System.Object as a parameter in WCF. As it is not serializable,I am getting the message as the operation is not supported as it uses System.Object. Any solution to this problem. When sending messages over the wire, WCF by default will only serialize what's enough to get the message across, ie, the members of the contracts. If your message takes
我有一个要求，我必须使用System.Object作为WCF中的参数。 由于它不是可序列化的，因为它使用System.Object，因此操作不受支持，所以我收到消息。 任何解决这个问题的方法。 在通过线路发送消息时，默认情况下，WCF将只序列化足够的信息，即合同的成员。 如果您的消息以“对象”作为参数，则需要使用类型信息通过线路发送额外的信息。 如果您在客户端和服务器上使用相同的程序集，则可以在服务器（和客户端）中使用NetDataCo
I've been trying to use a SilverLight client to call an ASP.Net WCF service that would return a Dictionary<string, object> . That worked fine when the values in the dictionary were simple types like int , string or Guid . However, I now have a scenario where I need one of the values to be an array of Dictionary<string, object> ! It all compiles fine and the signature of the se
我一直在尝试使用SilverLight客户端来调用ASP.Net WCF服务，该服务将返回一个Dictionary<string, object> 。 当字典中的值是像int ， string或Guid这样的简单类型时，它可以正常工作。 但是，我现在有一个场景，我需要其中一个值为Dictionary<string, object>的数组！ 这一切都编译好，服务的签名没有改变，但现在服务调用失败。 任何想法如何解决它？ 我试图使用KnownType和ServiceKnownType属性来注释我的
