c# Multiple WebRequest and WebResponse timeout problems.

Hi Everyone ,

In this tips and tricks article i wanna talk about when we use Multiple WebRequest object for interacting some urls getting timeout errors even if remote server not busy.
this is usually caused by not dispose some open WebResponse objects.You can also use “using” statement for disposing unnecessery objects .

For good example :

WebRequest wrGETURL;
wrGETURL = WebRequest.Create(sURL);
// wrGETURL.Proxy = myProxy;

durationTime = DateTime.Now;

using
(HttpWebResponse response = (HttpWebResponse)wrGETURL.GetResponse())
{
status = response.StatusCode.ToString();
TimeSpan ts = DateTime.Now – durationTime;
duration = ts.TotalMilliseconds.ToString();
}

Optional parameters for functions in c#

C# (before .net 4.0) does not support optional method arguments. However, there may be times when you are using components that were created in a language that supports optional arguments, such as legacy COM components or components created with Microsoft Visual Basic .NET.

class Example {    public void Test()     {        object missing = Type.Missing;       object urlblog = "http://blog.bugrapostaci.com";        VBTestService yourObject = new VBTestService();         // first parameter is url and other 3 are optional in definition of OptionalParameterFuction coded VB        yourObject.OptionalParameterFuction(ref urlblog, ref missing, ref missing, ref missing, ref missing);     } }

Happy Codding…

Here is a small example for getting day name of a date by specific culture:

 

DateTime startDate = DateTime.Now;

DateTime endDate = DateTime.Now.AddDays(2);

 

CultureInfo c = new CultureInfo("tr-TR");

string startDayName = c.DateTimeFormat.DayNames[(int)startDate.DayOfWeek];

string endDayName = c.DateTimeFormat.DayNames[(int)endDate.DayOfWeek];
