Wellens, Yes, casting in two steps as you describe above, first double, then float worked.

casting to int first will lose the decimal value. Consider this code: Dim x As Integer = 5 Dim y As Object = x Dim z As Decimal = CType(y, Decimal) No error from compiler or at runtime.

The C# standard isn't quite right: Paul Linton If the source operand is a reference to an incompatible object, a System.InvalidCastException is thrown.

Value types are made in system stack.

Implicit Conversion 2. when ran the code this line has given the error "specified cast is not valid". It's quick & easy. Draw some mountain peaks Why did the best potions master have greasy hair?

Converting to string and parsing is not a good way to attack the problem and incurs some overhead. C# new operator returns the memory address of the object. In a company crossing multiple timezones, is it rude to send a co-worker a work email in the middle of the night? However, it must be typed as an object once bound to the dataset because I get this error without the cast when trying to move a dataset item into a float

There we find (table 9) that boxing is more than 20 times as expensive than a simple assignment, and unboxing is 3-4 times as expensive. as if 1st time if youbox it in float, nextyou can notunbox that to double or vice versa. Apr 30, 2009 11:11 AM|smcirish|LINK Mr.

Since stucts/classes look the same to someone using them in code and could conceivably change, structs are inherently bad.

class Program { static void Main(string[] args) { decimal d = 23.88m; object o = (object)d; Console.Write((decimal)o); } } why it worked on the second code and not on the first So i would have to do something like int.Parse(dr["field1"].ToString()); dan Jul 8 '06 #4 This discussion thread is closed Start new discussion Replies have been disabled for this discussion.

Explicit conversion is carried out using casts.
