Giving parameters to a Func.

Hey, I am trying to make a command line that gets a string and the I call a function based off of said string. I am trying to use dictionaries because I think that'll be better than a super long list of if statements. But, I have run into an issue where I cannot figure out how to give a Funt parameters. Here's the code:

namespace example
{
  public static class CommandLine
  {
    // Dictionary with all valid commands and then the corresponding method.
    private static Dictionary<string, Func<string>> validCommands = new Dictionary<string, Func<string>>()
    {
      {"test", TestMethod}
    };

      // Called from else where in the program with the raw command string. Ex: "/test"
      public static string CommandParser(string rawCommand)
      {
        if (rawCommand != "")
        {
          // Removes the '/' from the string and split it to an array of words.
          string[] formattedCommand = rawCommand.Remove(0, 1).Split(" ");
          try
          {
            // Finds the command and runs the appropiate function.
            return $"Output: {validCommands[formattedCommand[0]].Invoke()}";
          }
          catch (KeyNotFoundException)
          {
            // If command isn't found this will be printed.
            return $"Invalid command \"{rawCommand}\".";
          }
        }
        else
        {
          // Returns an empty string to allow for new lines.
          return "";
        }
    }

    public static string TestMethod()
    {
      return "Yay it worked";
    }
  }
}

namespace example
{
  public static class CommandLine
  {
    // Dictionary with all valid commands and then the corresponding method.
    private static Dictionary<string, Func<string>> validCommands = new Dictionary<string, Func<string>>()
    {
      {"test", TestMethod}
    };

      // Called from else where in the program with the raw command string. Ex: "/test"
      public static string CommandParser(string rawCommand)
      {
        if (rawCommand != "")
        {
          // Removes the '/' from the string and split it to an array of words.
          string[] formattedCommand = rawCommand.Remove(0, 1).Split(" ");
          try
          {
            // Finds the command and runs the appropiate function.
            return $"Output: {validCommands[formattedCommand[0]].Invoke()}";
          }
          catch (KeyNotFoundException)
          {
            // If command isn't found this will be printed.
            return $"Invalid command \"{rawCommand}\".";
          }
        }
        else
        {
          // Returns an empty string to allow for new lines.
          return "";
        }
    }

    public static string TestMethod()
    {
      return "Yay it worked";
    }
  }
}

My question is, how do I modify this code so I can add parameters to TestMethod and still call it in this way. Or even if there is a better/cleaner way to build something like this I'll look into what ever information I'm provided. Thank you so much for any and all assistance.

✅ No SKD's?

Hello I am trying to use VSCode to code and I have installed DotNet 7.0.400 and I have downloaded the SKD's all in default locations. So, why is VSCode still telling me I don't have SDK's? Any Suggestions?

❔ C# extension is still Brokey

Hello helpers of the C# discord. So, a few weeks ago there was a bug in the C# Extension of VSCode. I believe that bug is now fixed, as there has been an update. But now it's telling me I have no SDK's installed. I have installed under the default path and the "dotnet --list-sdks" shows I have 7.0.400. What can I do to fix this issue and get the extension to work again?

❔ OmniSharp is Brokey

I updated the C# extension on VS Code and it told me I needed to update my C# to get OnmiSharp to work. I updated it to the latest version I could find, that being 7.0.10 but OmniSharp is asking for 7.0.100 and thus won't work. What can I do to fix this?

❔ CMD Causing Problems with Custom Input Class

I am working on a C# project that takes input from the user from CMD, and because I like my software to run a specific way I made my own Input Class. It adds a few things that the normal Console.ReadLine() does not include, like command histories and such. On Mac it runs perfectly, but I have not gotten it to work on windows because of a bothersome issue. With CMD while using the Console.ReadKey() and looping over it like this:

string input = "";
while (true)
{
  input += Console.ReadKey().Key.ToString();
}

string input = "";
while (true)
{
  input += Console.ReadKey().Key.ToString();
}

When you press backspace it moves the cursor over to the left one. I have noticed a few small issues like this, making getting CMD support difficult. My question is, is there a way to disable these shortcuts and just get the key input?
