Update table from webpage - asp.net-mvc

Question

I'm using a stored procedure to update a table when the user clicks approve however I get message that it was approved successfully but the table wasn't updated.
Update
I'm now only able to update one item; even I select more than one item it is only updating one.
Stored Procedure
Update RequisitionItem
set [status] = 0,
[approve_date] = #approve_date
--[ApprovedBy]=#ApprovedBy
where [status]=-1 and Req_No=#reqNumber and item_no=#item_no
Method
public void SetRequisitionStatus0(List <string> reqNumber,List <string> item_no)
{
SqlConnection connection = new SqlConnection(connectionString);
SqlCommand command = new SqlCommand();
command.CommandText = "requisition_sp_setstatus0";
command.CommandType = CommandType.StoredProcedure;
command.Parameters.Add("#reqNumber", SqlDbType.VarChar);
command.Parameters.Add("#item_no", SqlDbType.VarChar);
//command.Parameters.Add("#ApprovedBy", SqlDbType.VarChar);
command.Parameters.Add("#approve_date", SqlDbType.DateTime).Value = DateTime.Now;
using (command.Connection = connection)
{
try
{
connection.Open();
foreach (var item in reqNumbers)
{
command.Parameters["#reqNumber"].Value = item;
foreach (var item1 in item_no)
{
command.Parameters["#item_no"].Value = item1;
}
command.ExecuteNonQuery();
}
}
finally
{
connection.Close();
}
}
return;
}

I think the foreach loops are messing you up. The inner loop will loop the entire list (item_no) then go back to the outer loop, then the inner loop will go through the entire list again, always giving you the last item. You need a for loop, something like
for(int i = 0; i < reqNumbers.count; i++)
{
command.Parameters["#reqNumber"].Value = reqNumbers[i];
command.Parameters["#item_no"].Value = item_no[i];
command.ExecuteNonQuery();
}
you don't need to close the connection either - the using statement will close it automatically. and you don't need the final return.
