You need not use Where and the FirstOrDefault in this case, you can specify the filter condition inside the FirstOrDefault itself. But which will give you null if there are no records satisfying the condition(because in the absence of the first value it will give you the default value, for reference type objects the default … Read more
I’ve done something like before using the JavaScript serialization class: using System.Web.Script.Serialization; And: JavaScriptSerializer jss = new JavaScriptSerializer(); string output = jss.Serialize(ListOfMyObject); Response.Write(output); Response.Flush(); Response.End();
Go to xxx.resx file in Windows File Explorer. Right-click and select properties. At the bottom of the the dialog is an “unblock” option: Check this and click Apply. Clean your solution and it will build.
I recommend following pattern for debug: var ServiceToRun = new SomeService(); if (Environment.UserInteractive) { // This used to run the service as a console (development phase only) ServiceToRun.Start(); Console.WriteLine(“Press Enter to terminate …”); Console.ReadLine(); ServiceToRun.DoStop(); } else { ServiceBase.Run(ServiceToRun); } Edit: make sure that your target is Console Application, not Windows Application, otherwise it will … Read more

You can use AddHours, it will subtract hours if negative number is passed. DateTime dt1 = dt.AddHours(-6);
Neither. Your collection has a fixed size and std::array is sufficient. The data structure you implement is called a ring buffer. To implement it you create an array and keep track of the offset of the current first element. When you add an element that would push an item out of the buffer – i.e. … Read more
You can use SqlMethods.Like(). An example of the usage: var results = from u in users where SqlMethods.Like(u.FirstName, “%John%”) select u;
You can use Enumerable.Except to get distinct items from lines3 which is not in lines2: lines2.AddRange(lines3.Except(lines2)); If lines2 contains all items from lines3 then nothing will be added.
