^(([a-zA-Z0-9]|[a-zA-Z0-9][a-zA-Z0-9-]*[a-zA-Z0-9]).)*([A-Za-z]|[A-Za-z][A-Za-z0-9-]*[A-Za-z0-9])$ - Validation Expression for Host name

I want a limited amount of html tags for the user to be able to put in my form and by looking at the posts, regular expressions seem to be the way forward. I don't want to use javascript or 3rd party as this is for an assignment at university.
The examples I have found seem to be set out differently than mine with using asp id identifiers whereas my code below is set out differently so I am unsure if I can use these examples.
I am building a forum and I want to be able to use simple square bracket tags to allow users to format text. I am currently accomplishing this by parsing the string and looking for the tags. It's very tedious, especially when I run into a tag like this [URL]. Having to parse the attribute, and the value, and make sure it has proper opening and closing tags is kind of a pain and seems silly. I know how powerful regular expressions are but I'm not good at them and they frustrate me to no end. I think an example would get me started. Just a regex for finding tags like [b]bolded text[/b] and tags with attributes like the link

I am getting ready to just write my own, but I have a need for some regular expressions that will validate strings to make sure they are in an acceptable format to be inserted/updated into a database field. I figure it may just be to find a list of them someone has already posted somewhere and just use those.

I am trying to find a way to limit the inputs on a webpage to a variety of different sequences, and although I have worked through the regular expression library, I am still confused on how to allow decimal places and a maximum value. I initially used rangevalidators, but as you know, these only limit the inputs to a range, and have no control over the decimal places entered. A variety of limits i have been asked to implement are:
1. Range 0-45, 0 decimal places
2. Range 0-20, 2 decimal places
3. Range 16-65, 0 decimal places
4. Range 0-99, 2 decimal places
5. Range 0-1500000, 0 decimal places
6 Range 0-200, 1 decimal place
For 1 and 5 respectively, I have used
([0-9]|[0-9]d|45)$
([0-9]|[0-9]d|1500000)$
but want to be sure that I have understood the pattern correctly. How do I then go about creating a pattern for the other examples?
How to ignore route in ASP.NET vNext (MVC 6)?
Now I using the following routing config:
public void Configure(IApplicationBuilder app)
{
app.UseMvc();
app.UseMvc(routes =>
{
routes.MapRoute(
"Root",
"{*url}",
new { controller = "Root", action = "Root"}
);
});
}
The global root controller render a view in which I initialize AngularJS. It works for me, but I need to ignore routes for .css | .js | .*images_extensions* .
As I understood the following code doesn't work for this version of ASP.NET vNext:
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
How I can make ignoring of a route?
In the "Regular Expression Editor" dialog in VS 2008 ( or 2005 for this matter ) ,
there is a list of "standard expressions" like :
"French phone number" , "French postal code" etc..
And of course there is an option to select a "Custom" and then enter your own regular expression.
Well.. I want to add a predefined expressions to that list . Like : "Israeli phone number" .
I don't want to enter it every time by selecting a custom value .
I want my developers in the team available items for them to choose.
Anyone knows how to alter that list ?
I've found some question about it on the web - and the answer given is that it's not possible .

View 2 RepliesI have a ListBox that contains userNames which is inputted by a user during run time. This number of items in the ListBox is dependent on the user's input. These userNames will then be used in a Lambda expression like this:
var vHandleResult = vHandleResult.Where(a => a.UserName.Contains("userName"));
This works fine when there is only 1 user in the ListBox but doesn't produce the correct results when there are multiple items in the listBox. I tried manually creating the expression which should be written as this:
var vHandleResult = vHandleResult.Where(a => a.UserName.Contains("userName1") || a.UserName.Contains("userName2") || a.UserName.Contains("userName3") || a.UserName.Contains("userName4"));
I tried forming the "a.UserName.Contains("userName") expression as a string which is dependent on the number of the items (using foreach) and then just plug in the resulting string in the expression but it seems that it doesnt accept string as an expression.
