Creating new method c# methodname(Variable) -

-

I found a method like this ReadAsAsync & lt; T & gt; (This HttpContent content); in c # and I do not know what type of method and question popup on my head

"It is possible to create a method like 'MethodName & lt; varible & gt; (variable) {} ' and is this method elsewhere? "

For example: 

  Public Zune Alias ​​& lt; String getText> (string text) {getText = text; }   
 And when I call the method:  
  string sampleText; Legal name & lt; Sample text & gt; ("Hello World");   
 Then the value of  sampleText  will be  "Hello World" .  
 I know this type of method is useless because you can set the value of the sample such as  
  string sampleText = "";   
 But I just want to do some experiment, thanks.  
  
 
 
 
 I found some method  readAsAsync & lt; T & gt; (This HttpContent content); In C # and I do not know which type of method and question popup on my head   
 This is a  general method  By specifying this is what you want:  
  Foo results = wait for the response. the seminar. Readsink & lt; Foo & gt; (); You can read more about this on MSDN:  
 
 It is possible to make a method like "method method (variable) {} 'and it does so Is the method somewhere present? "  
 No, what you are trying to do is not possible.  & lt; ... & gt;  What is happening between a  type , no variable

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
