Reusing SqlCommand?

Question

I am not really sure if this is possible or not.

I am currently working on a college project and I have a function that uses stored procedures. I would like to know

Yes! You can definitely do that. Within a function you can re-use the same connection as well (I don't recommend re-using a connection object for larger scopes, but it is possible).

You could also do something like this:

myConStr = ConfigurationManager.ConnectionStrings["MyConnString"].ConnectionString;
using (var cn = new SqlConnection(myConStr) )
using (var cmd = new SqlCommand("team5UserCurrentBooks3", cn) ) 
{
    cmd.CommandType = CommandType.StoredProcedure; 
    cmd.Parameters.Add("@user_id", SqlDbType.Int).Value = userID;
    cmd.Parameters.Add("@book_id", SqlDbType.Int);
    cn.Open();

    for(int i = 0; i<10; i++)
    {
        cmd.Parameters["@book_id"].Value = i;
        cmd.ExecuteNonQuery();
    }
}

This will run the query 10 times and use the same user_id each time it executes, but change the book_id. The using block is just like wrapping your connection in a try/catch to make sure it's closed.
