DirectCast V CType

[hog]

Can some explain in laymans terms the difference between the to convertion keywords please.

 

I think I have it but just want to be sure. The help says

 

Dim Q As Object = 2.37

Dim I As Integer = CType(Q,Integer)

Dim J as Integer = DirectCast(Q,Integer)

 

I succeeds as 2.37 converts to an Integer...

 

J fails as Q was declared as an Object not an Integer so DirectCast fails.

 

Question is why use DirectCast instead of CType

 

Apologies incase this is a stupid question

[divil]

DirectCast is used to cast from one class to a sub or superclass of that type. The Convert class is used to convert one type to another, for example "3.141" to 3.141.

 

The CType function is a VB helper designed to decide which one to use. I avoid it as it isn't available in any other language.
