Array List Add(" "c) - [Resolved]

[mendhak]

I just came across this:

Dim objarrlist As New System.Collections.ArrayList
 
 
        objarrlist.Add(" "c)

How can we have a string followed by a c here? What exactly is this doing?

[Pirate]

c=Char .

so , you can only store one char type .

[Pirate]

This can clears it up :

Dim objarrlist As New System.Collections.ArrayList
        objarrlist.Add(" "c)
        Dim t As Type = objarrlist(0).GetType
        MessageBox.Show(t.ToString)

[mendhak]

So you mean, just one instance of a character in the entire array list?


Can there be other options instead of c?

[mendhak]

Looks like we posted at the same time.

I see that it converts whatever is in the string to a character.

Can this "z"c syntax be used in other places in VB.NET or is it specific to the arraylist?

[Pirate]

No , that would specify the type of the element you add . You can add char at index 0 , string at 1 , object at index 2 ..etc

Other uses for c is this (basically used with ToString method)

Dim c As Double = 102.01
Dim s As String = c.ToString("c")
MessageBox.Show(s)

for the complete list (D,d(for dates) , c ...etc) check MSDN Help (Formatting Overview)
