Problem with continue in While Loop within Try/Catch in C# (2.0)
- by csharpnoob
Hi,
when i try to use in my ASPX Webpage in the Code Behind this
try{
while()
{
...
db.Open();
readDataMoney = new OleDbCommand("SELECT * FROM Customer WHERE card = '" + customer.card + "';", db).ExecuteReader();
while (readDataMoney.Read())
{
try
{
if (!readDataMoney.IsDBNull(readDataMoney.GetOrdinal("Credit")))
{
customer.credit = Convert.ToDouble(readDataMoney[readDataMoney.GetOrdinal("Credit")]);
}
if (!readDataMoney.IsDBNull(readDataMoney.GetOrdinal("Bonus")))
{
customer.bonus = Convert.ToDouble(readDataMoney[readDataMoney.GetOrdinal("Bonus")]);
}
}
catch (Exception ex)
{
Connector.writeLog("Money: " + ex.StackTrace + "" + ex.Message + "" + ex.Source);
customer.credit = 0.0;
customer.credit = 0.0;
continue;
}
finally
{
}
}
readDataMoney.Close();
vsiDB.Close();
...
}
}catch
{
continue;
}
The whole page hangs if there is a problem when the read from db isn't working.
I tried to check for !isNull, but same problem.
I have a lots of differend MDB Files to process, which are readonly (can't repair/compact)
and some or others not. Same Design/Layout of Tables. With good old ASP Classic 3.0
all of them are processing with the "On Resume Next". I know I know. But that's how it is.
Can't change the source. So the basic question:
So is there any way to tell .NET to continue the loop whatever happens within the
try loop if there is any exception?
After a lots of wating time i get this exceptions:

Thanks for any help.
