C# console application in sharepoint

I have created a console application which interacts with Sharepoint Online using Microsoft CSOM and PnP. What I don't understand is how to deploy this code to Sharepoint and run it from Sharepoint. Any help would be greatly appreciated. I have included my code.

static void Main(string[] args)
{
    string siteUrl = "";
    string userName = "";
    SecureString password = new SecureString();
    string psd = "";
    foreach (char c in psd)
    {
        password.AppendChar(c);
    }

    AuthenticationManager am = new AuthenticationManager();


    using (var cc = am.GetSharePointOnlineAuthenticatedContextTenant(siteUrl, userName, password))
    {
        // Demo 1: Add empty page
        var page = cc.Web.AddClientSidePage();
        page.RemovePageHeader();
        page.ClearPage();


        var text = new ClientSideText();
        text.Text = "Hello PnP";

        page.AddControl(text, -1);

        page.Save("testpage2.aspx");
        page.DisableComments();
        page.Publish();


    }
}
