Parameters and quotes - wrong implementation

[tomasr78]

Could you let me know how to pass such a parameter?

user="this is the password"

The MedallionShell adds additional quotes on top of the current parameter.
If I split one parameter to two like this

user=
this is the password

It adds space between parameters and it becomes user= "this is the password" and command line breaks.

@tomasr78 what token(s) do you want the program to receive? What OS are you using?

If you want to send 2 tokens user= and this is the password, you should pass new[] { "user=", "\"this is the password\"" } to the command.

If you want to send just one token user=\"this is the password\", then you should pass just one token new[] { "user=\"this is the password\"" }.

A rare possibility is that you are dealing with a legacy program (likely written in a low-level language) that doesn't comply with the OS rules for how arguments should be escaped/tokenized. In this case, neither of the above will get you the desired behavior. To work around this, you can use a StartInfo initializer instead of passing explicit arguments:

Command.Run(
    "some.exe", 
     Array.Empty<object>(), 
     options: o => o.StartInfo(si => si.Arguments = "whatever string I want")
);

While this last case is theoretically possible from what I've read, in practice I've yet to come across a case where this was required. It is risky because you are giving up built-in command line escaping.
