I have an array.

I have the name of an element.
I need the related index.

Is there a sort of "GetIndex" method
or I have to use the For Next cicle
until I met the given name?
 
Tim,

The index you make yourself for an array.

by instance in VBNet
for i as integer = 0 to myArray.Length - 1
'do what you want
next

C#
For (int i=0;i<myArray.Lenght;i++){//do what you want}

Did you know by the way that there are special language newsgroups.
microsoft.public.dotnet.languages.vb or csharp or vs

I hope this helps,

Cor

Array.IndexOf(yourArray, yourName)

What exactly do you mean by the "name" of the element? If you mean the
name of a variable which was used to populate the array, that has no
meaning to the object itself which is referred to by the element.

That would find the index of the *value* though. I *suspect* the OP
wants to be able to do:

string x = "hello";
string y = "there";

string[] array = new string[2];
array[x] = 0;
array[y] = 1;

// The line you can't do
int index = ??? GetIndex ("x");

So does that mean you were actually looking for the value itself in the
array? It's worth being very clear on this - an array element doesn't
*have* a name as such. (It may have a Name property, depending on the
type, of course.)
 
I populated my array in this manner

Rome
then
Milan
then
Venice
then
Florence

Question:
I have Venice,
what position is it?

Now I solved .

Right - yes, as suspected, you have the value of the element.
