Troubles with .net data adapter v1.7

frameworks 1.1
studio 2003

my connect string:

FbConnectionStringBuilder cs = new FbConnectionStringBuilder();

cs.DataSource = "localhost";
cs.Database = "b1.gdb";
cs.UserID = "SYSDBA";
cs.Password = "masterkey";
cs.Dialect = 3;
cs.ConnectionLifeTime=0;
cs.Charset="WIN1251";
cs.ConnectionTimeout=30;
cs.PacketSize=8192;
cs.ServerType=3;
cs.Pooling=false;
cs.FetchSize=20;
cs.Port=3050;
string connectionString = cs.ToString();
----------------------------------------------------------
gives error:An invalid connection string argument has been supplied or a required connection string argument has not been supplied.
-----------------------------------------------------------
code:

string connectionString = "User=SYSDBA;" + "Password=masterkey;" + "Database=b1.gbd;" + "DataSource=localhost;" + "Port=3050;" + "Dialect=3;" + "Charset=WIN1251;" + "Role=;" + "Connection lifetime=15;" + "Pooling=true;" + "MinPoolSize=0;" + "MaxPoolSize=50;" + "Packet Size=8192;" + "ServerType=0";
----------------------------------------------------------
Invalid PInvoke metadata format.

what can I do?

P.S. Можно и по-русски

Connection string for connecting to Firebird in .NET applications:

“User=SYSDBA;Password=masterkey; Database=SampleDatabase.fdb; DataSource=localhost; Port=3050;Dialect=3;Charset=NONE;Role=; Connection lifetime=15;Pooling=true;MinPoolSize=0;MaxPoolSize=50;Packet Size=8192;ServerType=0″

Database connection strings

Or try this piece of code:

using System;
using System.Data;
using FirebirdSql.Data.Firebird;

public class Test
{
public static void Main(string[] args)
{
string connectionString =
"Database=C:PROGRAM FILESFIREBIRDEXAMPLESEMPLOYEE.GDB;" +
"User=SYSDBA;" +
"Password=masterkey;" +
"Dialect=3;" +
"Server=localhost";


IDbConnection dbcon = new FbConnection(connectionString);
dbcon.Open();
IDbCommand dbcmd = dbcon.CreateCommand();
string sql = "SELECT * FROM employee";
dbcmd.CommandText = sql;
IDataReader reader = dbcmd.ExecuteReader();
while(reader.Read()) {
object dataValue = reader.GetValue(0);
string sValue = dataValue.ToString();
Console.WriteLine("Value: " + sValue);
}
// clean up
reader.Close();
reader = null;
dbcmd.Dispose();
dbcmd = null;
dbcon.Close();
dbcon = null;
}
}
