I'm trying to pass the list of my class as DbParameter
. Probably the table type is defined in my stored procedure.
Now, I'm not getting how to pass the List<>
into the stored procedure as there is table type defined which accepts Tables
only.
Here, I'm putting my method.
public static AddCustomer(List<Customer> customer)
{
List<DbParameter> lstDbParameters = null;
try
{
#region Set the Parameters
lstDbParameters = new List<DbParameter>();
SqlParameter dbAcceptedBillDetails = new SqlParameter("@Customers",
customer);
dbAcceptedBillDetails.SqlDbType = SqlDbType.Structured;
lstDbParameters.Add(dbAcceptedBillDetails as DbParameter);
lstDbParameters.Add(CDDAC.MakeDbParameter(dbProvider,
"@ErrorMessage",
DbType.String,
null,
500,
ParameterDirection.Output));
#endregion
//Call the static ExecuteNonQuery method.
CDDAC.ExecuteNonQuery(dbProvider,
connectionString,
"AddCustomer",
CommandType.StoredProcedure,
lstDbParameters.ToArray());
}
catch (Exception ex)
{
throw;
}
}
And I'm getting error like this:
Failed to convert parameter value from a List
1 to a IEnumerable
1.
I know i can convert this list into DataTable
and then pass it in the stored procedure but it seems time consuming. :(
Finally, i got my answer byself. But during finding, i got that there is no way exist to convert List<>
to IEnumerable<>
directly.
But this article is very useful to transact data through object
or List<Obj>
very useful. :)
I know this question a bit old, but I found another way to pass a list to table type parameter by converting list into datatable. So your code can be like this :
public static AddCustomer(DataTable customer)
{
try
{
DbCommand dbcomm = CDDAC.GetStoredProcCommand("name your stored procedure");
CDDAC.AdInParameter(dbcomm, "@Param", SqlDbType.Structured, customer); //@param is an input parameter from your storedprocedure
CDDAC.ExecuteNonQuery(dbcomm);
}
catch (Exception ex)
{
throw;
}
}
Just make sure you have created type for data customer in your database.
