c#连接oracle数据库

连接字符串

public static string connstring = "user id=databasename;password=oraclepwd;data source=(description = (address_list= (address = (protocol = tcp)(host = ipaddress)(port = 1521))) (connect_data = (service_name = orcl)))";

引用命名空间

using oracle.manageddataaccess.client;

连接方法

public int getconn()
{
oracleconnection conn = new oracleconnection(connstring);
int result = 0;
try
{
conn.open();
result = 1;
}
catch (exception ex)
{
throw (ex);
}
finally
{
conn.close();
}
return result;
}

在其他地方就可以调用这个方法使用了
