Hi, I am trying to make sense of the below method, I would appreciate any correction\advice against my comments please
// Method signature declaration which accepts 2 parameters, the first a Database Command and the second an array of parameters of type Object
public static void SetParameters(this DbCommand command, object[] parms)
// Validation check to see the array of parameters is not null and of a length greater than 0
if (parms != null && parms.Length > 0)
// Loop through and add 2 to each loop???
for (int i = 0; i < parms.Length; i += 2)
// Convert the first parameter to string and store in a name variable
string name = parms[i].ToString();
// Not entirely sure
if (parms[i + 1] is string && (string)parms[i + 1] == "")
// Reset to null
parms[i + 1] = null;
// Again not entirely sure
object value = parms[i + 1] ?? DBNull.Value;
// Create the parameter object and and store in a local var named dbParameter
var dbParameter = command.CreateParameter();
// Set the name reference to the ParameterName property
dbParameter.ParameterName = name;
// Set the value reference to the Value property
dbParameter.Value = value;
// The add the dbParameter to the list of command parameters
command.Parameters.Add(dbParameter);
Thanks
