How to create a new .cs file in an existing project through the command line using .net 5.0

Question

I'm using .net core to create and run some very simple C# code through the command line. I create a new console app using dotnet new console . It creates a .csproj file in the name of the directory I'm in (classes). So I have a classes folder which contains a classes.csproj file, a Program.cs file and some other folders.

In order to create some classes I need some other .cs files here, but I can't find out how to do it. I've tried the File:New command according to https://learn.microsoft.com/en-us/dotnet/csharp/tutorials/intro-to-csharp/introduction-to-classes, but I must be using the wrong syntax since it says:

The filename, directory name, or volume label syntax is incorrect.

Since I'm pretty much new to command line and coding(obviously), I've googled for some cmd syntax but still couldn't find anything to get it work.

I know It can be easily done in Visual Studio but I was wondering if there is a way to do it using cmd.

'' > ./File.cs should do the trick but it depends on your shell. — Aluan Haddad

If you don't want to use VS or VS Code or any other IDE, you need to manually create the new .cs file and to manually add it to the .csproj using a text editor in an ItemGroup section: <ItemGroup><Compile Include="Dependencies\Windows Global Hotkey\Hotkey.cs"/></ItemGroup>. — user12031933

@OlivierRogier usually, with dotnet and new-style csproj, you don't need to add the .cs to the .csproj — Marc Gravell

Creating an empty .cs file isn't really a very useful thing - you're going to need some editor to put code in it; and: any editor is going to be able to create a new file. So... why not just do that? — Marc Gravell

Unfortunately, there is no command line to create a C# file in dotnet cli

but if you want to create a C# file with the terminal you can use bellow command

in Linux bash OR git bash in windows

touch YourFileName.cs

in Windows cmd

type NUL > YourFileName.cs
