c#怎么连接oracle数据库

Answer 1

通过ADO.Net连接数据库：
Oracle连接字符串：
string connStr = "Data Source=数据库服务名;user=用户名;password=密码";
try
{
using (OracleConnection oraconn = new OracleConnection(strConn))
{
oraconn.Open();
using (OracleCommand oracmd = oraconn.CreateCommand())
{
oracmd.CommandText = sql语句;
oracmd.ExecuteNonQuery()或oracmd.ExecuteScalar();
}
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
