使用c＃2010連接到oracle XE express

Question

剛剛用c＃開始。不確定快遞版本是否支持與oracle的連接。 如果有的話，任何人都可以讓我知道要做到這一點的步驟嗎？

謝謝你們。

使用ODP .NET ADO .NET Provider。你可以看到一個如何使用它的例子here。

從例如複製

using System; 
using System.Data; 
using Oracle.DataAccess.Client; 

... 

// Create the connection object 
OracleConnection con = new OracleConnection(); 

// Specify the connect string 
// NOTE: Modify User Id, Password, Data Source as per your database set up 
con.ConnectionString = "User Id=userid;Password=password;Data Source=dbinstance;"; 

try 
{ 
    // Open the connection 
    con.Open(); 
    Console.WriteLine("Connection to Oracle database established!"); 
    Console.WriteLine(" "); 
} 
catch (Exception ex) 
{ 
Console.WriteLine(ex.Message); 
} 

string cmdQuery = "SELECT empno, ename FROM emptab"; 

// Create the OracleCommand object 
OracleCommand cmd = new OracleCommand(cmdQuery); 
cmd.Connection = con; 
cmd.CommandType = CommandType.Text; 

try 
{ 
    // Execute command, create OracleDataReader object 
    OracleDataReader reader = cmd.ExecuteReader(); 
    while (reader.Read()) 
    { 
    // Output Employee Name and Number 
    Console.WriteLine("Employee Number: " + 
        reader.GetDecimal(0) + 
            " , " + 
         "Employee Name : " + 


         reader.GetString(1)); 
    } 
} 
catch (Exception ex) 
{ 
    Console.WriteLine(ex.Message); 
} 
finally 
{ 
    // Dispose OracleCommand object 
    cmd.Dispose(); 


    // Close and Dispose OracleConnection object 
    con.Close(); 
    con.Dispose(); 
}
