how to add a new parameter to SqlParameter[ ] Collection?

Question

I want to use something similar like this:

using (DataSet ds = new DataSet())
{
    SqlParameter[] dbParams = new SqlParameter[]
    {                                


        

Answer 1

Just use a list instead:

var parameters = new List<SqlParameter>
{
    new SqlParameter("@PromptID", promptID)
};
if (scenarioID != 0)
{
    parameters.Add(new SqlParameter("@ScenarioID", scenarioID));
}

If you really need an array at the end, you can always use:

var array = parameters.ToArray();

Answer 2

You should use List instead of array.

   List<SqlParameter> dbParams = new List<SqlParameter>(); 

and then you can do

   dbParams.Add(new SqlParameter("@PromptID", promptID);

Answer 3

var parameters = new List<SqlParameter>
{
    new SqlParameter("@PromptID", promptID),       
};

Answer 4

Other suggestion:

SqlParameter[] sqlPar = new SqlParameter[1];
sqlPar[0] = new SqlParameter("@System", "Teste");

Answer 5

If you know the maximum number of items (instanses of SQLParameter type) then following approach is ideal. Else you can go with List<SqlParameter> approach, which is briefed by peers.

 var dbParams = new SqlParameter[2];
 dbParams.SetValue(new SqlParameter("@PromptID", promptID),0);
 dbParams.SetValue(new SqlParameter("@ScenarioID", scenarioID), scenarioID != 0 ? 1 : 0);
