try..finally

if i do just try and finally without any catch if an exception ocurrs it will be ignored or a ExceptionFound message will pop up?

Doing this causes an error because it isn't caught:

Code:

---

try
{
        MessageBox.Show("hello");
        throw new System.Exception("My exception");
}
finally
{
        MessageBox.Show("Here is the finally block");
}

---

finally is optional.

catch is not.

If you don't want to catch the error, i.e. just ignore it, still put an empty catch:

Code:

---

try
{
    //Statement that might generate error
}
catch
{
}
