Question

我正在尝试将PostgreSQL数据库连接到C＃应用程序。为此，我创建了ODBC数据源，现在我需要连接字符串包含在C＃中。

问题：如何在C＃中为PostgreSQL编写DSN连接字符串？

Answer 1

试试这个

 // PostgeSQL-style connection string
   string connstring = String.Format("Server={0};Port={1};" + 
                    "User Id={2};Password={3};Database={4};",
                    tbHost.Text, tbPort.Text, tbUser.Text, 
                    tbPass.Text, tbDataBaseName.Text );
                // Making connection with Npgsql provider
   NpgsqlConnection conn = new NpgsqlConnection(connstring);
   conn.Open();
   // quite complex sql statement
   string sql = "SELECT * FROM simple_table";
   // data adapter making request from our connection
   NpgsqlDataAdapter da = new NpgsqlDataAdapter(sql, conn);
