How to create a Map[String,String] from Map[String, Any] in Scala? -

-

New in scale - How to map [string, string] to map , AA] are string strings of the map [string, ana] but I do not know how to enter " any or otherwise" to type " Type string ". As you've mentioned that all your values ​​have a string in the map, you can just asInstanceOf

if your assumption is incorrect, then you will get runtime exception as shown below: 
  $ scala Scala version 2.9.2 (OpenZK's 64-bit server VM, Java 1.7.0_55) Welcome to Type them in the expression to evaluate them. Type: Support for more information> Scala & gt; Map (string, any) = map ("foo" -> 5, "bar" -> 7.6, "baz" -> "qux") m: map [string, any] = map (foo - & Gt; 5, times -> 7.6, Falcon -> Cx) Scala & gt; Map (string, any) = map ("FU" -> 5 "," bar "->" 7.6 "," baz "->" qux ") m2: map [string, any ] = Map (FU -> 5, Bar -> 7.6, Falcon -> CX) Scala> M2.asInstanceOf [Map [String, String]] res0: Map [String, String] = Map (FU -> 5, Bar -> 7.6, Falcon -> Qux)   
 This is true when all values ​​are actually of type  string .  
  scala & gt; Res0 ("foo") res5: string = 5   
 For your misconceptions look:  
  scala> M.asInstanceOf [Map [String, String]] res2: Map [String, String] = Map (FU -> 5, Bar -> 7.6, Falcon -> CX) Scale & gt; Res2 ("foo") can not be molded into java.lang.String at java.lang.ClassCastException: java.lang.Integer & lt; Init & gt; (

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i...
