Slow DB Inserts. Is Reflection Really This Expensive?

I'm relatively new to compact framework and SQL Server Compact so bear with me if I've got an obvious thing I've forgotten.

I've written my own database helper layer. My idea is to generate SQL Insert statements dynamically based on what is in the contents of each object. Peformance however is horrible. I try to do 1800 inserts and it takes about 50 seconds on the device (Release Build, outside of the IDE).

I pass in a list of objects to be inserted which derive from a ModelBase class. ModelBase includes some ORM information (what table the object goes into. what fields are mapped to which properties). I generate one SQLCeCommand object, one sql string (new params for each insert), and am using SqlCeResultResultSets.

What can I do to make this run faster? Thank you





Code Snippet
public bool Insert(List<ModelBase> recs)
{
SqlCeConnection con = new SqlCeConnection(connectionString);

try
{
con.Open();
con.BeginTransaction();
}
catch
{
return false;
}

SqlCeCommand cmd = new SqlCeCommand();
cmd.Connection = con;
String sqlString = "INSERT INTO [" + recs[0].tableName + "] (";
String sqlString2 = ") VALUES (";
PropertyInfo[] props = recs[0].GetType().GetProperties();
for (int x = 0; x < props.Length; x++)
{
PropertyInfo pi = props[x];
if (recs[0].fieldMap.ContainsKey(pi.Name))
{

sqlString += "[" + recs[0].fieldMap[pi.Name] + "]";
sqlString2 += "@" + pi.Name;
sqlString += ", ";
sqlString2 += ", ";
}
}
sqlString = sqlString.Substring(0, sqlString.LastIndexOf(", "));
sqlString2 = sqlString2.Substring(0, sqlString2.LastIndexOf(", "));
sqlString += sqlString2 + ")";
cmd.CommandText = sqlString;
cmd.CommandType = CommandType.Text;
foreach (ModelBase rec in recs)
{
cmd.Parameters.Clear();
for (int x = 0; x < props.Length; x++)
{
PropertyInfo pi = props[x];
if (rec.fieldMap.ContainsKey((pi.Name)))
{
if (pi.GetValue(rec, null) == null)
cmd.Parameters.AddWithValue("@" + pi.Name, DBNull.Value);
else
cmd.Parameters.AddWithValue("@" + pi.Name, pi.GetValue(rec, null));
}
}

try
{
SqlCeResultSet rs = cmd.ExecuteResultSet(ResultSetOptions.None);
}
catch(Exception e)
{
cmd.Connection.Close();
cmd.Connection.Dispose();
Program.log.Error(e.Message,e);
return false;
}
}
con.Close();
return true;
