The following is a line of huge .txt file and i am reading it line by line. I need the value of second column. In this line, I need to extract 'C9006'.
Mr ABC|C9006|The white field,
ON|493-493-4939|493-493-4939|YR|Inactive
Note : The delimiter char is pipe sign '|'. The length of second column is not consistent.
What's the regular expression to check if a string starts with "mailto" or "ftp" or "joe" or...
Now I am using C# and code like this in a big if with many ors:
String.StartsWith("mailto:")
String.StartsWith("ftp")
It looks like a regex would be better for this. Or is there a C# way I am missing here?

I need to pull a SubString from a Linq Datasource, but can't use INTs per .SubString(int, int) I have strings such as xxxx.xxxx.xxxxx.AAAA.xxxx.xxxx.xxxx.xxx and I need to pull AAAA out. the preceeding x's will be varying lengths, so I can't use a static int. What I do know is that there will be a static number of periods (.) leading up to the AAAA. I can't figure out how to use the SubSting with characters rather than indexs. This is what I have so far:

I have an intranet application which I have been putting together with ASP.NET. I have been using VWD 2010 Beta 2 which has been fine so far. But when I go to deploy the work i've done so far to a local IIS a variable which is supposed to be; being filled with the value from HttpContext.Current.User.Identity.Name is not being filled i.e. an error occurs when substring goes out of bounds. I believe it is because the HttpContext.Current.User.Identity.Name is not putting a value into the string variable 'username'. But it is quite strange as when I run the website project within VWD 2010 it works fine without any errors. IIS is set to Integrated Windows Authentication and Annonomous Users are allowed.
public static String getName()
{
// Store username
String name = HttpContext.Current.User.Identity.Name;
// Truncate username from domain name
String[] substring = new String[1];
// Define the token at which the string will be broken at
char[] token = { '\' };
// Split the string
substring = name.Split(token);
// Return the username
return substring[1];
}
Any ideas why when running the exact same files from local IIS gives me errors?

I want to find a substring (email) in a large text using Regex.
just want to return the first valid email that is found from the input text:
example:
string inputString = "Our email is myname@ourcompany.com.
desired output: myname@ourcompany.com
this is the Regex pattern i've used: ^[A-Z0-9._%+-]+@[A-Z0-9.-]+.[A-Z]{2,4}$
- is this pattern correct?
Code:
private static void DumpHRefs(string inputString)
{
Match m;
string HRefPattern = @"^[A-Z0-9._%+-]+@[A-Z0-9.-]+.[A-Z]{2,4}$";
m = Regex.Match(inputString, HRefPattern,
RegexOptions.IgnoreCase | RegexOptions.Compiled);
while (m.Success)
{
Console.WriteLine("Found email " + m.Groups[1] + " at ".......

I'm concatenating a string in codebehind to use in a sql select statement.
