VS环境下C#控制台远程连接oracle数据库无需安装客户端非常简单

VS环境下C#控制台远程连接oracle数据库无需安装客户端非常简单

新增加的引用：Oracle.ManagedDataAccess

并在命名空间增加：

using Oracle.ManagedDataAccess.Client;

直接上代码：

 public void setConnectionString()
        {
            string hostaddress = "IP";
            string servername = "ABCD";
            string uid = "ABC";
            string pwd = "abc";
            connectionString = "Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=" + hostaddress + ")(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=" + servername + ")));Persist Security Info=True;User ID=" + uid + ";Password=" + pwd + ";";
        }

 public void openConnection()
        {
            conn = new OracleConnection(connectionString);
            conn.Open();
        }
        public void closeConnection()
        {
            conn.Close();
        }

 DataReader ptDataReader;            DataTable datat = new DataTable();            ptDataReader = new DataReader();            ptDataReader.setConnectionString();            ptDataReader.openConnection();
