I'm tyring to extract the file name from a path entered in a text box by
doing this:

string sFile = File1.Value;
string[] sArray = sFile.Split(new char[] {'/'});
sFile = sArray.GetValue(sArray.GetUpperBound(0));

However, I get the following error:
Compiler Error Message: CS0029: Cannot implicitly convert type 'object' to
'string'

I can't figure out how to correct this. Can someone help me here?

Thanks!
 
sFile = (string)sArray.GetValue(sArray.GetUpperBound(0));

GetValue returns an object. Alternative you should use the indexer [] to
access the elements of the array in a type-safe manner.

The easiest thing to do is avoid using the Array methods, and just use
the "normal" way of accessing arrays:

sFile = sArray[sArray.Length-1];

To correct your existing code, you could just add a cast to string
though.
 
Hi,

Are you on a web app ? cause otherwise you have the incorrect / , it should
be \ .

and if all you need is get the name of the file you can do this ( if a win
app )
string file = System.IO.Path.GetFileName ( sFile );

Don't know if there is a "web" version though.

Cheers,

Adding (string) did the trick. You lost me on the indexer thing.

You're right, the / was incorrect.

I am doing this on an ASP page and GetFileName worked great.

Thanks!
