Extracting A Number From A String Using Regex

static string ExtractNumbers(string expr)

{

return string.Join(null,System.Text.RegularExpressions.Regex.Split(expr, “[^\d]”));

}

Call as follows:

Response.Write (ExtractNumbers(“12EFR77”));

SELECT sysobjects.name
FROM syscolumns
LEFT JOIN sysobjects on sysobjects.id = syscolumns.id
WHERE syscolumns.name LIKE ‘%fieldname%’
ORDER BY 1

Converting Array to ArrayList:

ArrayList fileArrayList = = new ArrayList();

string[] files = Directory.GetDirectories(path)

fileArrayList.AddRange(files);

Converting ArrayList to Array:

ArrayList fileArrayList = new ArrayList();

//Populate fileArrayList

…

string[] files = (string[])fileArrayList.

ToArray(typeof(string));
