Search Engine

[kbipul]

Hi

In a web application , I need to create an aspx page(in C#) which can serach the files present on the server at the specified locations.

The search parameter may be the file name, extn name, location, fully or partly. The resulting file names should be displayed in a datagrid.

I am clueless about the functionality involved to create this search engine.

Can anyone help me?

The way this is normally done is through the use of metadata:
Metadata and Reflection in .NET

I could not get the task done . I have this sample code which is used to populate the gridview with the file names. This code is working fine


How can the results be filtered? Someone please edit the code so that it can filter the data. I am clueless.
