我需要通过 Visual Studio 2010 连接到 Oracle DB(外部)。但我不想在我的机器上安装 Oracle。在我的项目中,我引用了:System.Data.OracleClient。但它并没有满足需求。我有一个“Oracle SQL Developer IDE”,我在其中针对 oracle db 运行 SQL 查询。
到目前为止我有这个代码:
private static string GetConnectionString()
{
String connString = "host= serverName;database=myDatabase;uid=userName;pwd=passWord";
return connString;
}
private static void ConnectingToOracle()
{
string connectionString = GetConnectionString();
using (OracleConnection connection = new OracleConnection())
{
connection.ConnectionString = connectionString;
connection.Open();
Console.WriteLine("State: {0}", connection.State);
Console.WriteLine("ConnectionString: {0}",
connection.ConnectionString);
OracleCommand command = connection.CreateCommand();
string sql = "SELECT * FROM myTableName";
command.CommandText = sql;
OracleDataReader reader = command.ExecuteReader();
while (reader.Read())
{
string myField = (string)reader["MYFIELD"];
Console.WriteLine(myField);
}
}
}
到目前为止,我阅读了这些博客:

到目前为止,我还没有从 Oracle 下载任何东西。我应该采取哪些步骤来实现这一点?
