Question

I know I am forgetting to remember how to do this and it is late.

I want to, in an elegant manner, build a placeholder list for a munged sql command.

Have a command with an arbitrary number of parameters, need to build ?,?,?

Did I mention that it was a wet brain fart? this is what came out:

You are welcome to make me feel like more of an idiot if you just remember me what I am forgetting. 😉

Ok, looks like I should be calling it a night.

Both you guys confirmed what I was doing before going off the deep end.

This is my name list,

string names = string.Join(",", _command.Parameters.Cast<SQLiteParameter>().Select(p => p.ParameterName).ToArray());

And I just replaced the p.Name with ‘?’

string vals = string.Join(",", _command.Parameters.Cast<object>().Select(p => "?").ToArray());

But for some reason I did not approve.

Thanks.

Along the lines of @Jon’s answer:

string.Join(",", _command.Parameters.Cast<object>().Select(p => "?").ToArray())
