I have a function on my cshtml page that checks if an entered email is valid, it works as it should, however i now need to move it into an external file, with all the other functions I've created, I cant seem to find any information on this, can anyone tell me what file extension the file should have? I know it needs to go into the App_Code folder, am I supposed to do anything special to my function? and how do I call it on my web page? My lecturer literally has no notes covering this.
bool IsEmail(string email) {
//declare the return variable
bool rst = false;
System.Text.RegularExpressions.Regex regex = new System.Text.RegularExpressions.Regex(#"^([\w\.\-]+)#([\w\-]+)((\.(\w){2,3})+)$");
// does the string follow the regex structure?
System.Text.RegularExpressions.Match match = regex.Match(email);
//if yes
if (match.Success){
rst = true;
} else {
rst = false;
}
return rst;
}
Thanks in advance
In a new file in App_Code:
public static class GodObject {
public static bool IsEmail(string email) {
//declare the return variable
bool rst = false;
System.Text.RegularExpressions.Regex regex = new System.Text.RegularExpressions.Regex(#"^([\w\.\-]+)#([\w\-]+)((\.(\w){2,3})+)$");
// does the string follow the regex structure?
System.Text.RegularExpressions.Match match = regex.Match(email);
//if yes
if (match.Success){
rst = true;
} else {
rst = false;
}
return rst;
}
}
Then you can reference GodObject.IsEmail(...) from just about anywhere.
This is probably what your prof is after, however, there are far better ways to approach this validation.

I have code that is not throwing any error. I have used NDesk option set and added 2 string Parameters. I can see it has pulled correct names in args. But when I uses parse(args) it is not throwing an error. So I am assuming it is working.
I am trying to check if p(args) is true or false. But I can not use bool expressions to List<string>.
Any help how I can accomplish that. I want execute function if parse has correct arguments.
My code is like this
private static Regex fileNamePattern = new Regex(#"^[A-Z0-9]{8}-[A-Z0-9]{4}-[A-Z0-9]{4}-[A-Z0-9]{4}-[A-Z0-9]{12}[.]pdf$", RegexOptions.Compiled | RegexOptions.IgnoreCase);
//missing method name
{
string inputFile;
string outputFile;
var p = new OptionSet() {
{"i"," pdf file",v=>inputFile=v},{"o","index file with kws",v=>outputFile=v},
};
Console.WriteLine($"args length: {args.Length}");
Console.WriteLine($"args 0: {args[0]}");
Console.WriteLine($"args 1: {args[1]}");
p.Parse(args); //I would like to use this if(parse(args))
{
}
//
}
private static void UpdateImportIndexFile(string inputFile, string outputFile)
{
using (var dip = File.CreateText(outputFile))
{
var match = fileNamePattern.Match(Path.GetFileName(MainFilePath));
if (match.Success)
{
//create text file (outputfile);
}
}
}
Since p is an instance of a class and the parse method does not support a return to emulate in a sense the functionality of a TryParse wrap your parse in a try block
try{
val = p.Parse(args);
}catch(OptionException e){
//if false
}

I am creating a multi form application which has a series of validation test before the user can save the form. One of those validation functions needs evaluate if the user has entered certain keywords, such as 'Unkown', 'TBA', 'N/A'.I need to begin by normalizing the input string, to strip all unwanted characters such as Whitespace, and extra casing such as 'UNkown', 'tBA'. This then needs to be checked against my list.
This is my current method however my regex doesn't normalize my input string correctly and will pass validation if there is a space in-front of the word
public bool useUnkownEntity(string strTest)
{
Regex rgx = new Regex(#"^[a-zA-Z]");
List<string> unkown = new List<string> { "Unkown", "tba", "tbc","N/a"};
useUnkownEntity(rgx.Replace(strTest, ""));
if (unkown.Contains(strTest, StringComparer.OrdinalIgnoreCase))
{
MessageBox.Show("please refre to the unkown ENtity within");
return false;
}
return true;
}
My desired result be false if any of the desired words are found iregardless if they are not a exact match. What would be the best approach, to capture all possibilities a user may enter to get passed validation.
This is the event I am calling the method from
private void txt_SurName_Validating(object sender, CancelEventArgs e)
{ // Convert User input to TitleCase
if (useUnkownEntity(txt_SurName.Text))
{
return;
}
if (string.IsNullOrWhiteSpace(txt_SurName.Text))
{
epSurname.Clear(); _IsValid = true;
}
else if (util.IsAllLetters(txt_SurName.Text))
{
epSurname.Clear(); txt_SurName.Text = util.ToTitle(txt_SurName.Text); _IsValid = true;
}
else
{
epSurname.SetError(txt_SurName, "InValid Surname"); _IsValid = false;
}
}
This is my answer so far, it ignores casing but not spacing, if I enter a few spaces at the beginning of the word it will fail, just as it will if a / is forgotten on N/A.
public bool useUnkownEntity(string strTest)
{
Regex rgx = new Regex("[^a-zA-Z/s/ ]");
List<string> unkown = new List<string> { "Unkown", "tba", "tbc","N/A"};
strTest = rgx.Replace(strTest, "");
if (unkown.Contains(strTest, StringComparer.OrdinalIgnoreCase))
{
MessageBox.Show("Please refer to the unkown Entity within!!");
return false;
}
return true;
}
I must use a text file "db.txt" which inherits the names of the Server and Database to make my connection string complete.
db.txt looks like this:
<Anfang>
SERVER==dbServer\SQLEXPRESS
DATABASE==studentweb
<Ende>
The connection string:
string constr = ConfigurationManager.ConnectionStrings["DRIVER={SQL Server}; SERVER=SERVER DATABASE=DB UID=;PWD=;LANGUAGE=Deutsch;Trusted_Connection=YES"].ConnectionString;
Unfortunatly we are only allowed to use Classic ASPX.net (C# 2.0) and not the web.config.
I've searched a lot, but found nothing close to help me.
Somebody got an Idea how to make it work?
Here is something to get you going.
In a nutshell, I put the DBInfo file through a method that reads the file line by line. When I see the line <anfang> I know the next line will be important, and when I see the line <ende> I know it's the end, so I need to grab everything in between. Hence why I came up with the booleans areWeThereYet and isItDoneYet which I use to start and stop gathering data from the file.
In this snippet I use a Dictionary<string, string> to store and return the values but, you could use something different. At first I was going to create a custom class that would hold all the DB information but, since this is a school assignment, we'll go step by step and start by using what's already available.
using System;
using System.Collections.Generic;
namespace _41167195
{
class Program
{
static void Main(string[] args)
{
string pathToDBINfoFile = #"M:\StackOverflowQuestionsAndAnswers\41167195\41167195\sample\DBInfo.txt";//the path to the file holding the info
Dictionary<string, string> connStringValues = DoIt(pathToDBINfoFile);//Get the values from the file using a method that returns a dictionary
string serverValue = connStringValues["SERVER"];//just for you to see what the results are
string dbValue = connStringValues["DATABASE"];//just for you to see what the results are
//Now you can adjust the line below using the stuff you got from above.
//string constr = ConfigurationManager.ConnectionStrings["DRIVER={SQL Server}; SERVER=SERVER DATABASE=DB UID=;PWD=;LANGUAGE=Deutsch;Trusted_Connection=YES"].ConnectionString;
}
private static Dictionary<string, string> DoIt(string incomingDBInfoPath)
{
Dictionary<string, string> retVal = new Dictionary<string, string>();//initialize a dictionary, this will be our return value
using (System.IO.StreamReader sr = new System.IO.StreamReader(incomingDBInfoPath))
{
string currentLine = string.Empty;
bool areWeThereYet = false;
bool isItDoneYet = false;
while ((currentLine = sr.ReadLine()) != null)//while there is something to read
{
if (currentLine.ToLower() == "<anfang>")
{
areWeThereYet = true;
continue;//force the while to go into the next iteration
}
else if (currentLine.ToLower() == "<ende>")
{
isItDoneYet = true;
}
if (areWeThereYet && !isItDoneYet)
{
string[] bleh = currentLine.Split(new string[] { "==" }, StringSplitOptions.RemoveEmptyEntries);
retVal.Add(bleh[0], bleh[1]);//add the value to the dictionary
}
else if (isItDoneYet)
{
break;//we are done, get out of here
}
else
{
continue;//we don't need this line
}
}
}
return retVal;
}
}
}
I have a security application called Siteminder. It creates unique URLS for every authentication. HTTPS://SITE/idp/**RANDOMURLSTRING**/resumeSAML20/idp/startSSO.ping
How can i capture the Unique URL and have the test continue to login.
A webtest assumes the next URL in the process. It does not support[Or I don't know how] a unique redirect to a random URL. Does anyone know of a way to handle this case?
EDIT:
My Solution -- Replace the SessionID with {{SessionID}} in all the URLS and use this extraction rule
public class ExtractSiteMinderCustomUrl : ExtractionRule
{
public string SiteMinderSessionID { get; private set; }
// The Extract method. The parameter e contains the web performance test context.
//---------------------------------------------------------------------
public override void Extract(object sender, ExtractionEventArgs e)
{
//look for anchor tags with URLS
Regex regex = new Regex("<a\\s+(?:[^>]*?\\s+)?href=\"([^\"]+\\?[^\"]+)\"");
MatchCollection match = regex.Matches(e.Response.BodyString);
if (match.Count > 0)
{
foreach (Match ItemMatch in match)
{
if (ItemMatch.ToString().Contains("/idp/"))
{
//start and ends string from the sitemindersession is in the link on the page
e.WebTest.Context.Add(this.ContextParameterName, GetStringBetween(ItemMatch.ToString(), "/idp/", "/resume"));
e.Success = true;
return;
}
}
e.Success = false;
e.Message = String.Format(CultureInfo.CurrentCulture, "Not Found in Link : /idp/");
}
else
{
e.Success = false;
e.Message = String.Format(CultureInfo.CurrentCulture, "No href tags found");
}
}
public static string GetStringBetween(string token, string first, string second)
{
if (!token.Contains(first)) return "";
var afterFirst = token.Split(new[] { first }, StringSplitOptions.None)[1];
if (!afterFirst.Contains(second)) return "";
var result = afterFirst.Split(new[] { second }, StringSplitOptions.None)[0];
return result;
}
}
The simple answer is to have use extraction rule that gets the **RANDOMURLSTRING** then change the URLs in the requests to be, for example, HTTPS://SITE/idp/{{TheRandomString}}/resumeSAML20/idp/startSSO.ping where TheRandomString is the context parameter that holds the extracted value. Note the doubled curly braces ({{ and }}) around the context parameter.
Suppose a value returned by the first redirection needs to be captured but a normal web test would redirect again and so the response is not seen by the extraction rules. In this case need to handle the redirect explicitly. Set the Follow redirects property of the initial request to false then add extraction rule(s) to gather the wanted values. Add a new request after the initial request and use the extracted values in it as necessary. It is possible to extract the entire redirected url and set the Url field to the extracted value.
Given an absolute URI/URL, I want to get a URI/URL which doesn't contain the leaf portion. For example: given http://foo.com/bar/baz.html, I should get http://foo.com/bar/.
The code which I could come up with seems a bit lengthy, so I'm wondering if there is a better way.
static string GetParentUriString(Uri uri)
{
StringBuilder parentName = new StringBuilder();
// Append the scheme: http, ftp etc.
parentName.Append(uri.Scheme);
// Appned the '://' after the http, ftp etc.
parentName.Append("://");
// Append the host name www.foo.com
parentName.Append(uri.Host);
// Append each segment except the last one. The last one is the
// leaf and we will ignore it.
for (int i = 0; i < uri.Segments.Length - 1; i++)
{
parentName.Append(uri.Segments[i]);
}
return parentName.ToString();
}
One would use the function something like this:
static void Main(string[] args)
{
Uri uri = new Uri("http://foo.com/bar/baz.html");
// Should return http://foo.com/bar/
string parentName = GetParentUriString(uri);
}
Thanks,
Rohit
Did you try this? Seems simple enough.
Uri parent = new Uri(uri, "..");
This is the shortest I can come up with:
static string GetParentUriString(Uri uri)
{
return uri.AbsoluteUri.Remove(uri.AbsoluteUri.Length - uri.Segments.Last().Length);
}
If you want to use the Last() method, you will have to include System.Linq.
There must be an easier way to do this with the built in uri methods but here is my twist on #unknown (yahoo)'s suggestion.
In this version you don't need System.Linq and it also handles URIs with query strings:
private static string GetParentUriString(Uri uri)
{
return uri.AbsoluteUri.Remove(uri.AbsoluteUri.Length - uri.Segments[uri.Segments.Length -1].Length - uri.Query.Length);
}
Quick and dirty
int pos = uriString.LastIndexOf('/');
if (pos > 0) { uriString = uriString.Substring(0, pos); }
Shortest way I found:
static Uri GetParent(Uri uri) {
return new Uri(uri, Path.GetDirectoryName(uri.LocalPath) + "/");
}
PapyRef's answer is incorrect, UriPartial.Path includes the filename.
new Uri(uri, ".").ToString()
seems to be cleanest/simplest implementation of the function requested.
I read many answers here but didn't find one that I liked because they break in some cases.
So, I am using this:
public Uri GetParentUri(Uri uri) {
var withoutQuery = new Uri(uri.GetComponents(UriComponents.Scheme |
UriComponents.UserInfo |
UriComponents.Host |
UriComponents.Port |
UriComponents.Path, UriFormat.UriEscaped));
var trimmed = new Uri(withoutQuery.AbsoluteUri.TrimEnd('/'));
var result = new Uri(trimmed, ".");
return result;
}
Note: It removes the Query and the Fragment intentionally.
new Uri(uri.AbsoluteUri + "/../")
Get segmenation of url
url="http://localhost:9572/School/Common/Admin/Default.aspx"
Dim name() As String = HttpContext.Current.Request.Url.Segments
now simply using for loop or by index, get parent directory name
code = name(2).Remove(name(2).IndexOf("/"))
This returns me, "Common"
Thought I'd chime in; despite it being almost 10 years, with the advent of the cloud, getting the parent Uri is a fairly common (and IMO more valuable) scenario, so combining some of the answers here you would simply use (extended) Uri semantics:
public static Uri Parent(this Uri uri)
{
return new Uri(uri.AbsoluteUri.Remove(uri.AbsoluteUri.Length - uri.Segments.Last().Length - uri.Query.Length).TrimEnd('/'));
}
var source = new Uri("https://foo.azure.com/bar/source/baz.html?q=1");
var parent = source.Parent(); // https://foo.azure.com/bar/source
var folder = parent.Segments.Last(); // source
I can't say I've tested every scenario, so caution advised.
