I had this method to insert new company to database but I have problem with List<Contacts> because I want to be able to insert multiple contact for company. Could someone help me?
public static bool AddNewCompany(Company company,List<Contacts> contact , Location local)
{
// get a configured DbCommand object
DbCommand comm = GenericDataAccess.CreateCommand();
// Set the stored procedure name
comm.CommandText = "AddNewCompany";
//create new parameter @CompanyName
DbParameter param = comm.CreateParameter();
param.ParameterName = "@CompanyName";
param.Value = company.CompanyName;
param.DbType = DbType.StringFixedLength;
comm.Parameters.Add(param);
//create new parameter @CompanyDetail
param = comm.CreateParameter();
param.ParameterName = "@CompanyDetail";
param.Value = company.CompanyDetail;
param.DbType = DbType.StringFixedLength;
comm.Parameters.Add(param);
//create new parameter @ModifiedDate
param = comm.CreateParameter();
param.ParameterName = "@ModifiedDate";
param.Value = DateTime.Now;
param.DbType = DbType.DateTime;
comm.Parameters.Add(param);
//Company Info
foreach (var c in contact)
{
//create new parameter @LabelContactTypeID
param = comm.CreateParameter();
param.ParameterName = "@LabelContactTypeID";
param.Value = c.LabelContactTypeID;
param.DbType = DbType.StringFixedLength;
comm.Parameters.Add(param);

Your stored procedure is inserting only one contact for the company. If you would like to add another contact (or more of them), write another procedure that will insert new contacts using the CompanyID from the last company inserted to the database.
I can’t write you code because I don’t know the tables and can’t replicate the results, but you should create another procedure from this code
In the first part just add one contact from the list (the first one that is on index 0 in the list)
Read the CompanyID of company that has been just inserted and for each other contact in the list, using this ID call your new procedure. It will add new contacts that are referenced to the company using the same companyID (referential identity one to many).
EDIT You should do something like this:
}
Create a new method that adds new contact using the part of the procedure I pasted here and insert all other contacts. Pas to this method a companyID.
