C#

*  Integer arithmetic overflow either throws an OverflowException or discards the most significant bits of the result (see below). Integer division by zero always throws a DivideByZeroException.<br />
* Floating-point arithmetic overflow or division by zero never throws an exception, because floating-point types are based on IEEE 754 and so have provisions for representing infinity and NaN (Not a Number).<br />
* Decimal arithmetic overflow always throws an OverflowException. Decimal division by zero always throws a DivideByZeroException.

I suppose one solution would be to pass the SqlConnection as a parameter to the function that will be working on it but for some reason I don't like that.

using (SqlConnection mySqlConnection = new SqlConnection(...))
{
   myFunc1(ref mySqlConnection );
   myFunc2(ref mySqlConnection );
}

private SqlConnection mySqlConnection = null;
using (mySqlConnection = new SqlConnection(...))
{
   myFunc1();
   myFunc2();
}

public class MyDAL : IDisposable
{
   SQLConnection mySqlConnection = null;
   public MyDAL()
   {
       mySqlConnection = new SqlConnection(...);
   }

   public void Dispose()
   {
        //Dispose connection here
   } 
}

using(MyDAL dal = new MyDAL())
{
    //Call MyFun1,MyFun2
}
