Passing list of IDs to WHERE IN from C# code

Question

Challenging issue you have encountered already ?

This is my challenge.

I have the query as follows - MSSQL Server 2017 calling from my C# application.

SQL

update slides set isBorrowed=0, updated_by='Daniel'
where id in (1,2,3);

C# code to achieve above

'Update Slides SET isBorrowed=1,updated_by=@update_by WHERE id IN (@ids)'

   string updateDonorQuery = "UPDATE slides " +
                            "SET isBorrowed=1,updated_by=@updated_by WHERE id IN (@ids)";
                        command.CommandText = updateDonorQuery;
                        command.CommandType = CommandType.Text;
                   command.Parameters.AddWithValue("@ids",list_ids.Split(',').Select(int.Parse).toList());
                   command.Parameters.AddWithValue("@updated_by", "Full name

Now The error is saying : "Exception on my command not expecting to receive list"

Then , i have changed to a string like this:

string list_ids = "1,2,3";

command.Parameters.AddWithValue("@ids",list_ids);
command.Parameters.AddWithValue("@updated_by", "Full name")

Agin code throw exception that complainant i have passed in nvarchar values instead of int. I guess interested the code as '1,2,3' when getting ids.

Guys i need a breakthrough , i hate loops.
