c# - Take a ScreenShot of my Control - Winform -

-

I want to take a screenshot of your control Winform I am using this function - Search this site: 

  Public Zero GetImage () {var bm = new bitmap (display1.Width, display1.Height); Display1.DrawToBitmap (BM, display1.ClientRectangle); BM. Save (@ "C: \ Whatever Jeff", image format.GF); }   
 But when I am using it, then system me There is an error about System.Drawing.dll in System.Runtime.InteropServices.ExternalException '': A common error occurred in GDI +.  
 Do you have any ideas? Thanks!  
 ---------------------- Edit ------------------ - --------  
 Well I have your function is altered in this way:  
  public void GetImage () {var bm = new bitmap (display1 .Width, Display 1.High); Display1.DrawToBitmap (BM, display1.ClientRectangle); Var dlg = new SaveFileDialog {DefaultExt = "png", filter = "Png files. * .png"}; var res = dlg.ShowDialog (); If (res == DialogResult.OK) BM Save (dlg.FileName, ImageFormat.Png); }   
 And it works but I now have an empty picture:   
 
 
 Try the following: There is a rectangle assuming display1, which limits the area of ​​the area on which you want to capture.  
  Public Zero GetImage () {rectangle display1 = this.Bounds; // // For the full screen using winforms control bounds // "= Screen.GetBounds (Point.Empty); var bm = new Bitmap (display1.Width, display1.Height); //display1.DrawToBitmap (BM, display1. ClientRectangle); graphics g = graphics. Fmaimej (BM); g. copy Fremskrin (new point (display 1. left display 1. helmet), point. Apti, display 1. Size); var Dielji = new Sevfail dialog {default Act = "png", filter = "png files | * .png "}; var res = dlg.ShowDialog (); if (res == DialogResult.OK) Bimksev (dlg.FileName, ImageFormat.Png);}

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
