Report Viewer(Visual Studio) Error: use a custom assembly with a RDLC report -

-

  • I'm trying to add a dll to report to the viewer so that I can remove the contents of a single field Decoding the report) is using the method from that dll.
  • I've added a dll in the report properties - & gt; Reference.
  • All methods (used to make DLL) in class library are static.

  • Classroom contents in that class library: ABCClass.cs (dll is used to create ABCCollection.dll) 

      name space ABCCollection {public class ABCClass {public stable string customformat string (string s) {// do some operations on the return; }}}     
     In Report1.rdlc, I am using the value for the field:  
      = ABCCollection ABCCLAS. Custom Formatt String ("Test")   
     But once I run this report, I get an error:  
      error while loading the code module : One? ??? ABCCollection, version = 1.0.0.0, culture = neutral, PublicKeyToken = nullâ ???? Description: One of the files or assembly 'ABCC selection, version = 1.0.0.0, culture = neutral, public keynote = faucet' or its dependency could not be loaded, the system failed to detect the specified file.   
     Can anyone help me with this?  
      
     
     
     Check the namespace given by DLL project properties, usually it's name of the project In this case, you are actually defining the namespace twice. It will be made to call the DLL:  
     ABCCollection.ABCCollection.ABCClass.CustomFormatString ("Test")

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
