Getting a list of files which contain the matching text

    //Setup the search parameters
    SearchParms parms = new SearchParms();

    //This is the directory to search
    parms.DirectoriesToSearch.Add(@"c:\_git");

    //Include all C# files by wildcard
    parms.FilesToInclude.Add("*.cs");
    parms.FileIncludeSearchType = FileSearchType.Wildcard;

    //Search for a plain text phrase
    parms.SearchString = "public partial class";
    parms.SearchExpressionType = SearchExpressionType.PlainText;

    //Search with the parameters
    FileSearchLogic logic = new FileSearchLogic();
    List<string> results = logic.SearchFiles(parms);

    foreach (var filePath in results)
    {
        Console.WriteLine(filePath);
    }

 

Getting a list of locations in a file which contain the matching text

    //Set the file to load
    string filePath = @"C:\_git\Compare-Net-Objects\Compare-NET-Objects-Tests\TestClasses\Invoice.cs";

    //What to search in the file
    SearchParms searchParms = new SearchParms();
    searchParms.SearchString = "FirstName";
    searchParms.SearchExpressionType = SearchExpressionType.PlainText;

    //Load the matches for the file
    LoadFileMatchesLogic loadFileMatchesLogic = new LoadFileMatchesLogic();
    LoadFileResult loadFileResult = loadFileMatchesLogic.LoadFileMatches(searchParms, filePath);

    foreach (var matchLocation in loadFileResult.MatchLocations)
    {
    Console.WriteLine($"{matchLocation.MatchText}: Start {matchLocation.StartPosition}, Length {matchLocation.Length}");
    }

 

Creating and Searching an index

    //Setup the search parameters
    SearchParms searchParms = new SearchParms();

    //This is the directory to index
    searchParms.DirectoriesToSearch.Add(@"c:\_git");

    //Include all C# files by wildcard
    searchParms.FilesToInclude.Add("*.cs");
    searchParms.FileIncludeSearchType = FileSearchType.Wildcard;

    //Set the directory to save the index
    searchParms.IndexPath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), "FileSearchLibrarySearchIndexExample");

    //Create the index
    IndexLogic indexLogic = new IndexLogic();
    indexLogic.CreateIndexIfItDoesNotExist(searchParms);

    //Specify what to search
    searchParms.SearchString = "public partial class";
    searchParms.SearchExpressionType = SearchExpressionType.PlainText;

    //List the files that are found
    List<string> files = indexLogic.SearchIndex(searchParms);

    foreach (string file in files)
    {
    Console.WriteLine(file);
    }
