Question

given the following text file:

Find all "HeaderText="", Subfolders, Find Results 1, "Entire Solution"
  C:\Documents and Settings\user\My Documents\Visual Studio 2008\Projects\WebApplication1\WebApplication1\Default.aspx(16):                <asp:BoundField DataField="CustomerID" HeaderText="CustomerID" ReadOnly="True" 
  C:\Documents and Settings\user\My Documents\Visual Studio 2008\Projects\WebApplication1\WebApplication1\Default.aspx(18):                <asp:BoundField DataField="CompanyName" HeaderText="CompanyName" 
  C:\Documents and Settings\user\My Documents\Visual Studio 2008\Projects\WebApplication1\WebApplication1\Default.aspx(20):                <asp:BoundField DataField="ContactName" HeaderText="ContactName" 
  Matching lines: 3    Matching files: 1    Total files searched: 5

what’s the best way to put just the filename and the value of HeaderText in a collection?

for example,

var test = new List<KeyValuePair<string,string>>();

test.Add(Default.aspx, CustomerID);
test.Add(Default.aspx, CompanyName);
test.Add(Default.aspx, ContactName);

You could use regular expressions:

public IEnumerable<KeyValuePair<string, string>> Parse(StreamReader reader)
{
    string line;
    while ((line = reader.ReadLine()) != null)
    {
        var tokens = Regex.Split(line, @"\(\d+\)\:");
        if (tokens.Length > 1)
        {
            var file = Path.GetFileName(tokens[0]);
            var match = Regex.Match(tokens[1], @"HeaderText=\""(\w+)\""");
            if (match.Success)
            {
                yield return new KeyValuePair<string, string>(
                    file, match.Groups[1].Value
                );
            }
        }
    }
}

which could be called like this:

using (var reader = File.OpenText("test.txt"))
{
    foreach (var item in Parse(reader))
    {
        Console.WriteLine("file: {0}, header: {1}", item.Key, item.Value);
    }
}
