You need to add a reference to System.Drawing.dll. As mentioned in the comments below this can be done as follows: In your Solution Explorer (Where all the files are shown with your project), right click the “References” folder and find System.Drawing on the .NET Tab.
Project > Properties> Application tab > change Output type to “Windows application”. No more console window.
We needed the ability to log from a console app and a windows service in addition to our ASP.NET site. I used the answer (ErrorLog.GetDefault(null);) which worked well until I needed to email too. So, here is my solution. It handles the log, email, tweet and filtering (both in the config file and in code). … Read more
printf(“\e[1;1H\e[2J”); This function will work on ANSI terminals, demands POSIX. I assume there is a version that might also work on window’s console, since it also supports ANSI escape sequences. #include <unistd.h> void clearScreen() { const char *CLEAR_SCREEN_ANSI = “\e[1;1H\e[2J”; write(STDOUT_FILENO, CLEAR_SCREEN_ANSI, 12); } There are some other alternatives, some of which don’t move the … Read more
You should also consider using Debug.WriteLine, that’s probably what you’re looking for. These statements are written out the trace listeners for your application, and can be viewed in the Output Window of Visual Studio. Debug.WriteLine(“constructor fired”);
Actually you can do it pretty simple, since the list have a ForEach method and since you can pass in Console.WriteLine as a method group. The compiler will then use an implicit conversion to convert the method group to, in this case, an Action<int> and pick the most specific method from the group, in this … Read more
You don’t get a return value from Task.WaitAll. You only use it to wait for completion of multiple tasks and then get the return value from the tasks themselves. var task1 = GetAsync(1); var task2 = GetAsync(2); Task.WaitAll(task1, task2); var result1 = task1.Result; var result2 = task2.Result; If you only have a single Task, just … Read more
Note: This answer shows how to switch the character encoding in the Windows console to (BOM-less) UTF-8 (code page 65001), so that shells such as cmd.exe and PowerShell properly encode and decode characters (text) when communicating with external (console) programs with full Unicode support, and in cmd.exe also for file I/O.[1] If, by contrast, your … Read more
The easiest option is to start a windows forms project, then change the output-type to Console Application. Alternatively, just add a reference to System.Windows.Forms.dll, and start coding: using System.Windows.Forms; [STAThread] static void Main() { Application.EnableVisualStyles(); Application.Run(new Form()); // or whatever } The important bit is the [STAThread] on your Main() method, required for full COM … Read more
It means that you don’t have a suitable entry point for your application at the moment. That code will nearly work with C# 7.1, but you do need to explicitly enable C# 7.1 in your project file: <LangVersion>7.1</LangVersion> or more generally: <LangVersion>latest</LangVersion> You also need to rename MainAsync to Main. So for example: Program.cs: using … Read more
