copy a file to a table in postgresql using C# npgsql driver and how to get a single \ when using path names -

-

I am trying to do a per-tab-delimited text file in a # e-drive from a server in # post in postgresql.

My SQL command 

  NPGSQL COMMAND CMD = "NPGXLL COMMAND" ("Copy scrap (glove_post_date, stock_number, stock_description, reasoncode, adjusted_tk, unicast, extended_host, week, cost , Catch_Ol) "+ Filename +"; ", Conn);   
 Here is my path code  
  string r = @ "e: \"; String t = txtFileName.Text; Filename = r + t;   
 I check my filename variable and it returns the path with a double backslash which I want to return to e: \ file.txt  
 I p < p> Thanks   
 
 
 The backslash has a special meaning in the string in C #, for example  \ n  is a new line,  \ t  is a tab ... and  \\  is actually a backslash; these combinations of backslash and a character are esec The sequence is called. However, in your example, you used the so-called literally string literally. At the beginning of the string, @ means that a backslash should be considered as any other character within the string (it disables escape sequences). In other words,  @ "e: \"  is the same thing as  "e: \\"  and it's okay. See also articles and questions for more information.  
 I also suggest using the  Path.Combine  method to enter the drive name with a file name in a trusted way.

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
