Solution 1

Use System.IO.DirectoryInfo.
or check whether you have reference to System.IO

ya now the error is finished but the image is not display in listview
now what to do

Sergey Alexandrovich Kryukov 12-Jul-11 3:04am

Same time. Yes, almost correct, but: 1) System.IO referenced as System (not System.IO which is a part of it); 2) there are two more forms of using name space; please see my solution.

Solution 2

Stop programming without learning how to use name spaces.

Use:

C#

System.IO.DirectoryInfo dir = new System.IO.DirectoryInfo(directoryName);

or

C#

using System.IO;

//...

DirectoryInfo dir = new DirectoryInfo(directoryName);

or

C#

using DirectoryInfo = System.IO.DirectoryInfo; //alias

//...

DirectoryInfo dir = new DirectoryInfo(directoryName);

ok i will but you are no body to say like this be polite during sharing information its happen sometime that you miss little things it dosent you degrade someone but still i thans for your co operation.

Just the opposite: when I make a mistake, I fix it and say thank you and allow myself no exclusions.

Let's see what you do. I help you and simply give you a general advice on how to approach programming (I mean, read manual on the language; how come you see anything negative in it?), and what do you do in response? Very nice. Who is impolite? Just think about it.

Now, will you consider formally accepting this answer (green button)? -- thank you.
