I was reading a best practices document created by the DotNetSpider team which covered many aspects of programming in .NET. I was really impressed by it and I think its a very good reference document. So I’ve decided to make a series of posts where I’ll post sections of their document covering a specific topic.

I was creating a website which had pages with multiple views. I wanted a fairly simple sitemap solution, without creating any custom sitemap provider, which could show the current view name in the breadcrumb trail like this – Home >> Parent Page >> Current Page >> Current View 1 Home >> Parent Page >> Current [...]
protected ArrayList getURL(string txtIn) { ArrayList outURL = new ArrayList(); Regex r = new Regex(“href\\s*=\\s*(?:(?:\\\”(?<url>[^\\\"]*)\\\”)|(?<url>[^\\s]* ))”); MatchCollection mc1 = r.Matches(txtIn); foreach (Match m1 in mc1) { foreach (Group g in m1.Groups) { outURL.Add(g.Value); } } return outURL; }
I’m using this function to filter common words out of a search query. protected string removeCommonWords(string sourceStr) { string[] seperator = { ” ” }; string[] ignoreWords = { “a”, “all”, “am”, “an”, “and”, “any”, “are”, “as”, “at”, “be”, “but”, “can”, “did”, “do”, “does”, “for”, “from”, “had”, “has”, “have”, “here”, “how”, “i”, “if”, “in”, “is”, [...]
This code will strip out all the HTML tags and truncate the text to 4 lines. public static string TruncateText(string txtIn, int newLength) { string txtOut = txtIn; string pattern = @”<(.|\n)*?>”; //Strip out HTML tags if (Regex.IsMatch(txtIn, pattern, RegexOptions.None)) txtOut = Regex.Replace(txtIn, pattern, string.Empty, RegexOptions.Multiline).Trim(); if (txtOut.Length > newLength) { int endPos = txtOut.LastIndexOf(” [...]
Find a control within a control recursively: protected void Control FindControlRecursive(Control Root, string Id) { if (Root.ID == Id) return Root; foreach (Control Ctl in Root.Controls) { Control FoundCtl = FindControlRecursive(Ctl, Id); if (FoundCtl != null) return FoundCtl; } return null; }

Check to see if all the controls within a specific control are valid: protected bool checkIsValid(Control c) { bool result = true; foreach (Control child in c.Controls) { if (child is BaseValidator && !((IValidator)child).IsValid) { return false; } result = result & checkIsValid(child); } return result; }
