POAccess appSettings in web.config from Thread in Class Library project
text
Body
copied!<p>Can I able to access <code>appSettings</code> section in my ASP.NET web.config file from a method in another referenced Class Library project when it is called as a new <code>Thread</code>? I'm accessing the setting through a property as</p> <pre><code> private static string TempXmlFolder { get { return System.Web.HttpContext.Current.Server.MapPath(ConfigurationManager.AppSettings["ReceiptTempPath"] ?? "~/Receipts/TempXML"); } } </code></pre> <p>There is an extension method for the matter to generate the receipt.</p> <pre><code> internal static void GenerateReceipt(this IMatter matter) { try { string XmlFile = TempXmlFolder + "/Rec_" + matter.MatterID + ".xml"; // ... // Generating receipt from the matter contents // ... // Saving generated receipt } catch (Exception ex) { ex.WriteLog(); } } </code></pre> <p>I'm calling the receipt generation as a new thread from the class library like</p> <pre><code> Thread printThread = new Thread(new ThreadStart(this.GenerateReceipt)); // To avoid exception 'The calling thread must be STA, because many UI components require this' (Using WPF controls in receipt generation function) printThread.SetApartmentState(ApartmentState.STA); printThread.Start(); // ... // Do another stuffs // ... // Wait to generate receipt to complete printThread.Join(); </code></pre> <p>But since the <code>HttpContext.Current</code> is null inside the <code>Thread</code>, I'm not able to access the current web server configuration file.</p> <p>Can you suggest there any way other than passing the current <code>HttpContext</code> to the <code>Thread</code>? If no, what are the things I've to take care to keep thread safety?</p> <h2>Edit #1</h2> <p>Currently I'm passing the HttpContext to the thread like</p> <pre><code> System.Web.HttpContext currentContext = System.Web.HttpContext.Current; Thread printThread = new Thread(() => this.GenerateReceipt(currentContext)); </code></pre> <p>and in the function,</p> <pre><code> internal static void GenerateReceipt(this IMatter matter, System.Web.HttpContext htCont) { string TempXmlFolder = htCont.Server.MapPath(ConfigurationManager.AppSettings["ReceiptTempPath"] ?? "~/Receipts/TempXML"); //... </code></pre>
