.Net Core - copy to clipboard?

Question

Is it possible to copy something to the clipboard using .Net Core (in a platform-agnostic way)?

It seems that the Clipboard class is missing, and P/Invoking is

Answer 1

Clipboard class is missing, hope in near future will be add an option for that. While it happen ... you can run a native shell command with ProcessStartInfo.

I'm noob in Net Core, but create this code to send and string to clipboard on Windows and Mac:

OS Detection Class

public static class OperatingSystem
{
    public static bool IsWindows() =>
        RuntimeInformation.IsOSPlatform(OSPlatform.Windows);

    public static bool IsMacOS() =>
        RuntimeInformation.IsOSPlatform(OSPlatform.OSX);

    public static bool IsLinux() =>
        RuntimeInformation.IsOSPlatform(OSPlatform.Linux);
}

Shell Class
Based on https://loune.net/2017/06/running-shell-bash-commands-in-net-core/

public static class Shell
{
    public static string Bash(this string cmd)
    {
        var escapedArgs = cmd.Replace("\"", "\\\"");
        string result = Run("/bin/bash", $"-c \"{escapedArgs}\"");
        return result;
    }

    public static string Bat(this string cmd)
    {
        var escapedArgs = cmd.Replace("\"", "\\\"");
        string result = Run("cmd.exe", $"/c \"{escapedArgs}\"");
        return result;
    }

    private static string Run (string filename, string arguments){
        var process = new Process()
        {
            StartInfo = new ProcessStartInfo
            {
                FileName = filename,
                Arguments = arguments,
                RedirectStandardOutput = true,
                UseShellExecute = false,
                CreateNoWindow = false,
            }
        };
        process.Start();
        string result = process.StandardOutput.ReadToEnd();
        process.WaitForExit();
        return result;
    }
}

Clipboard Class

public static class Clipboard
{
    public static void Copy(string val)
    {
        if (OperatingSystem.IsWindows())
        {
            $"echo {val} | clip".Bat();
        }

        if (OperatingSystem.IsMacOS())
        {
            $"echo \"{val}\" | pbcopy".Bash();
        }
    }
}

Then Finally, you can call Clipboard Copy and can get the value on the clipboard.

var dirPath = @"C:\MyPath";
Clipboard.Copy(dirPath);

Hope it help others! Improvements are welcome.

I'm working in a ToolBox library for .net core with all this things: https://github.com/deinsoftware/toolbox (also available as NuGet Package).
