How to reuse SqlCommand parameter through every iteration?

Question

I want to implement a simple delete button for my database. The event method looks something like this:

private void btnDeleteUser_Click(object sender, Event         


        

Answer 1

Rather than:

command.Parameters.AddWithValue("@id", rowUserID);

Use something like:

System.Data.SqlClient.SqlParameter p = new System.Data.SqlClient.SqlParameter();

Outside the foreach, and just set manually inside the loop:

p.ParameterName = "@ID";
p.Value = rowUserID;
