Is there a way to hide the console window when executing a console application?

问题 I have a List which contains all databases names. I have to dispaly the items contained in that list in the Console (using Console.WriteLine() ). How can I achieve this? 回答1: 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.

问题 In .NET framework, you can make a single .EXE file that will run from the command line without having any extra config files (and if using ILMerge, you can put all .DLL references into the 1 .EXE assembly). I am taking a stab at using .NET Core to accomplish the same thing, but so far without success. Even the simplest Hello World application with no dependencies requires there to be a file named <MyApp>.runtimeconfig.json in order to run using dotnet.exe . dotnet F:\\temp\\MyApp.dll The
