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
