Search string in multiple files.

i need to check a text in a lakh of files. as now am looping through files, is there any other fast approach to make it work easily.

are the files all in 1 folder?

vb Code:

Dim relevantFileNames As ReadOnlyCollection(Of String) = My.Computer.FileSystem.FindInFiles(My.Application.Info.DirectoryPath, ComboBox1.Text, False, FileIO.SearchOption.SearchTopLevelOnly, "*.txt")

FindInFiles parameters are:

• directory to search
• text to find
• ignore case
• search options
• file wildcards

Consider using the windows default file search

My.Computer.FileSystem.FindInFiles Method

Edit:Little slow in posting :)

yes.. but having subfolders..

Thanks,paul & Dana.. i check and come back..

Findinfiles looping through all files(Pls refer this..).. its taking much time in directory.getfiles().
Is there any other API which uses Search using some indexing techniques? i need the data in seconds..

The link says Data base connection Error. Do you want to search only in few file types . If yes the consider using the wild cards

Code:

---

Dim value As System.Collections.ObjectModel.ReadOnlyCollection(Of String) =

My.Computer.FileSystem.FindInFiles(directory ,containsText ,ignoreCase ,searchType ,"*.txt")
