| - | ===== Sample C# Program ===== | ||
| - | |||
| - | The following is a very simple C# program that shows a basic connection to an Omnidex Environment and simple query processing. | ||
| - | |||
| - | <code csharp> | ||
| - | using System; | ||
| - | using System.Collections.Generic; | ||
| - | using System.Text; | ||
| - | using System.Data.Odbc; | ||
| - | |||
| - | namespace OdxODBCSample | ||
| - | { | ||
| - | class OdxODBCSample | ||
| - | { | ||
| - | static void Main(string[] args) | ||
| - | { | ||
| - | Console.WriteLine("Omnidex Sample C# Program"); | ||
| - | |||
| - | string connString = | ||
| - | @"DRIVER={Omnidex};CONNECTIONSTRING=[server1:7555]c:\class\simple.xml"; | ||
| - | string sqlselect = @"select NAME, PHONE from INDIVIDUALS"; | ||
| - | OdbcConnection conn = null; | ||
| - | OdbcDataReader reader = null; | ||
| - | try | ||
| - | { | ||
| - | // Open Connection | ||
| - | conn = new OdbcConnection(connString); | ||
| - | conn.Open(); | ||
| - | // Execute the SQL statement | ||
| - | OdbcCommand cmd = new OdbcCommand(sqlselect, conn); | ||
| - | reader = cmd.ExecuteReader(); | ||
| - | // Display output header | ||
| - | Console.WriteLine("NAME\tPHONE\n"); | ||
| - | // Process the result set | ||
| - | while (reader.Read()) | ||
| - | { | ||
| - | Console.WriteLine( | ||
| - | "{0}\t{1}", | ||
| - | reader.GetString(0), | ||
| - | reader.GetString(1) | ||
| - | ); | ||
| - | } | ||
| - | } // try | ||
| - | catch (Exception e) | ||
| - | { | ||
| - | Console.WriteLine("Sql Error: " + e); | ||
| - | } | ||
| - | finally | ||
| - | { | ||
| - | try | ||
| - | { | ||
| - | if (reader != null) | ||
| - | reader.Close(); | ||
| - | if (conn != null) | ||
| - | conn.Close(); | ||
| - | } | ||
| - | catch (Exception e) | ||
| - | { | ||
| - | Console.WriteLine("Close Error: " + e); | ||
