How to convert c# linq code to code ?


I found useful  code that converts System.Array to String, but i couldn't succeed to implement to my application.

Any help would be great.


string[] foo = someObjectArray.OfType<object>().Select(o => o.ToString()).ToArray();

Wrong.  That code gives an array of strings, not a string.

Hi Hakan,

Please give this one a try:
someObjectArray.OfType(Of Object)().[Select](Function(o) o.ToString()).ToArray()

If this truly is an array, then the OfType call is really extraneous here--having the Select alone should be sufficient.

Agreed.  It could simply be:
Dim foo As String() = someObjectArray.Select(Function(s) s.ToString).ToArray

You could also use Array.ConvertAll():
Dim foo As String() = Array.ConvertAll(someObjectArray, Function(s) s.ToString)

The big question is if one string is required as the result.  Note how the question was worded - it converts array to string

4 objects in an array each contain in order one of the following words "this" "is" "a" "string"
After running the code one has an array of four strings "this" "is" "a" "string"
The result is NOT one string "this is a string"

@Mike your code is give an error on visual studio editor. It says "Select" is not member of array.
Make sure:
