What is c# equivalent to DirectCast in VB..?

Dim intListPrice As Integer = 0
Dim rowList As New Collection
Dim intCoutner As Integer = 1

intListPrice = intListPrice + DirectCast(rowList(intcolCounter), Object())(10)

What is meaning of above code and what is equivalent code in c#?

your code is not correct and throws an exception. ('System.IndexOutOfRangeException')

Hey

Your lines I will make in to c# language as below

int intListPrice = 0;
Collection rowList = new Collection();
int intCoutner = 1;

intListPrice = intListPrice + (object[])rowList(intcolCounter)(10);

Hi

If you take an object of unknown type and try
to cast it to the desired type, then it is the same
as C#'s () cast:
VB:
Dim o As Object = SomeObject()
Dim i As Integer = DirectCast(o, Integer)
C#:
object o = SomeObject();
int i = (int)o;

This is because, if o is typed as a System.Object,
then the () operation in C# will attempt to unbox
it. This will fail if the types don't match exactly;
for instance, if o is a boxed System.Double,
then (int)o will throw an exception because o must be unboxed as a System.Double before it can be
converted to a System.Int32

Hi

You can go through below CODE



int intListPrice = 0;
Collection rowList = new Collection();
int intCoutner = 1;

intListPrice = intListPrice + (object[])rowList(intcolCounter)(10);
