How to pass parameter from an array in c#?

Question

I want to assign a value parameter dynamic through an array. For example, the array arr_param will contain two value [0] = "abc" , [1] = "ZYX" .Now, I will assign them .The problem here is that i must specify the correct elements [0] , [1] after run foreach, I tried do it but failed convert to int

string[] arr_param  =  array_parameter.Split(';');
foreach (DataRow parmRow in parmsDataTable.Rows)
{
    string parmName = parmRow[parmNameDataColumn].ToString();
    cmd.Parameters.AddWithValue(parmName, arr_param[Convert.ToInt32(parmsDataTable.Rows)]);
}

I get error Unable to cast object of type 'System.Data.DataRowCollection' to type 'System.IConvertible' .

Answer 1

parmsDataTable.Rows is a DataRowCollection and it can't be converted to int .

A Simple Solution:

string[] arr_param  =  array_parameter.Split(';');
int counter = 0;
foreach (DataRow parmRow in parmsDataTable.Rows)
{
   string parmName = parmRow[parmNameDataColumn].ToString();
   cmd.Parameters.AddWithValue(parmName, arr_param[counter++)]);
}

Or:

string[] arr_param  =  array_parameter.Split(';');
foreach (DataRow parmRow in parmsDataTable.Rows)
{
   string parmName = parmRow[parmNameDataColumn].ToString();
   cmd.Parameters.AddWithValue(parmName,arr_param[parmsDataTable.Rows.IndexOf(parmRow))]);
}
