    DataTable dataT = new DataTable();
    dataT = objToDataTable(arr);


    string connStr = @" DataSource = C:\Users\gobol\Desktop\UK.db; Version =3";
    //After finister

    Finisar.SQLite.SQLiteConnection sqlite_conn;
    Finisar.SQLite.SQLiteCommand sqlite_cmd;
    Finisar.SQLite.SQLiteDataReader sqlite_datareader;

    // create a new database connection:
    sqlite_conn = new Finisar.SQLite.SQLiteConnection("Data Source=database.db;Version=3;New=True;Compress=True;");
    //  sqlite_conn = new Finisar.SQLite.SQLiteConnection(connStr);

    // open the connection:
    sqlite_conn.Open();

    // create a new SQL command:
    sqlite_cmd = sqlite_conn.CreateCommand();

    // Let the SQLiteCommand object know our SQL-Query:
    sqlite_cmd.CommandText = "CREATE TABLE test (id integer primary key, text varchar(100));";

    // Now lets execute the SQL ;D
    sqlite_cmd.ExecuteNonQuery();

    // Lets insert something into our new table:
    sqlite_cmd.CommandText = "INSERT INTO test (id, text) VALUES (1, 'Test Text 1');";

    // And execute this again ;D
    sqlite_cmd.ExecuteNonQuery();

    // ...and inserting another line:
    sqlite_cmd.CommandText = "INSERT INTO test (id, text) VALUES (2, 'Test Text 2');";

    // And execute this again ;D
    sqlite_cmd.ExecuteNonQuery();

    // But how do we read something out of our table ?
    // First lets build a SQL-Query again:
    sqlite_cmd.CommandText = "SELECT * FROM test";

    // Now the SQLiteCommand object can give us a DataReader-Object:
    sqlite_datareader = sqlite_cmd.ExecuteReader();

    // The SQLiteDataReader allows us to run through the result lines:
    while (sqlite_datareader.Read()) // Read() returns true if there is still a result line to read
    {
        // Print out the content of the text field:
        //System.Console.WriteLine(sqlite_datareader["text"]);
        string op = sqlite_datareader.GetString(0);
    }

    // We are ready, now lets cleanup and close our connection:
    sqlite_conn.Close();
}

我必须在系统中创建一个sqlite文件，同时与soap api交互.Here Soap api返回一些数据所以从那个数据我必须创建数据库文件。我可以通过Windows应用程序创建，但不能用于Web应用程序，因为之后我必须在调用Web应用程序的特定设备上传数据库文件。
