CType(x,Integer) vs. Integer.Parse(x)

Hello All:

Does anyone know the difference between CType(x,Integer) vs.
Integer.Parse(x)? Is there a performance advantage to one or the other?

TIA,
 
CType:

Returns the result of explicitly converting an expression to a specified
data type, object, structure, class, or interface.

Parse :

Parses the string parameter and converts it to an integer value.


CType is compiled inline, which means that the conversion code is part of
the code that evaluates the expression. In some cases there is no call to a
procedure to accomplish the conversion, which makes execution faster

Michel,

It sounds like CType is really the way to go.

Thanks.

Michel,

One more question:

Can you think of an ocassion when one would want to use Integer.Parse(x) or
Double.Parse(x) in lieu of CType(x,Integer) or CType(x,Double)?

If you're comparing VB conversion 'macros' (they aren't methods) and .NET
methods, then the correct .NET comparison is the System.Convert methods, not
the various "Parse" methods or C# casts.
