I have a string that I am grabbing that is input as:
05/22/2015
Eligibility
05/06/2015
Date of Death
I need 05/06/2015. The dates will change as the program runs through a database, and I am just a little unsure on how to always be grabbing the correct one.

So you need the second date only? Is it always going to be the 3rd line? If so you can do
var secondDate = myData.Split(new [] { Environment.NewLine }, StringSplitOptions.None)[2];
If the new line isn't for certain; /n vs /r/n, use:
var secondDate = myDate.Split(Environment.Newline.ToCharArray(), StringSplitOptions.RemoveEmptyEntries)[2];

If I understand you correctly, your string has 4 lines and you want the part of the string between linebreak 2 and 3.
Search for the positions of the second and third linebreak \n and use the substring derived of these positions.

Im trying to edit a postcode data which comes as for example 1234567 and i want to put a dash between 123 and 4567 (e.g 123-4567) is it possible to do this within C# without editing the csv file itself?
Im using a generic for loop to read through the csv file but i want to edit it like i asked above.
foreach(string line in csvData_){
string[] col = line.Split(',');
deliveryAddress.Text = col[0];
deliveryPostcode.Text = col[1];
deliveryPostcode contains 1234567 for e.g.
To solve your problem, you can use the method Insert() of the string object.
For example:
deliveryPostcode.Text = col[1].Length == 7 ? col[1].Insert(3, "-") : col[1];
You have to fit it for your needs, but this is the way I would use.
Here is the MSDN page of the String.Insert().

I have a string input which looks like:
var price = "£1.33(including postage)";
I'd like to take out the first part of the string before ( so that the output of regex would look like this:
"£1.33"
I'm new with Regex so I'm not quite sure how to do this, can someone help me out?
P.S. I thought of doing a substring, but that wouldn't work since price can have more decimals, and can be a larger price, so this option definitely wouldn't work
do you have to use regex?
much easier if you use split
string result = price.Split('(').First();
You don't need Regex for this if you have the same basic format of the "price" just different values.
var result = price.Substring(0, price.IndexOf("("));.

I have two urls:
http://sp2013/sites/1234
and
http://sp2013/pwa/projectsites/projectdetails.aspx?projuid=1234-123-123-123456-123456
I want to get from the first url the last part (always a number)
1234
and from the second url also the last part (guid)
1234-123-123-123456-123456
How could i achieve this through RegEx or maybe with string operations in C#?
string s = "http://sp2013/sites/1234";
var firstURLlastPart = new Uri(s).Segments.Last();
string s = "http://sp2013/pwa/projectsites/projectdetails.aspx?projuid=1234-123-123-123456-123456";
var secondURLlastPart = s.Split('=').Last();
Just split at '/' and take the last chunk for the first case.
str.Split('/').Last()
Split at '=' and take last chunk for second case
str.Split('=').Last()
(?!\/|\=).[-0-9]+$
It's working for both. But it also accepts if in first example will be number in format like this:
12345-4568

I have a C# task to do and I am stuck on part of the coding. I am using StreamReader to read a .txt file which contains group exam grade data (e.g. ADCBCBBBADEBCCBADBAACDCCBEDCBACCFEABBCBBBCCEAABCBB), I need the code to work out how many A's, B's etc there are inside each set of data, I thought about using some form of count++ code but each attempt just throws errors.
I want it to print onto console the number of A's in that line of the .txt file.
I hope that makes sense, I understand how to do the rest but I just needed a hand on this section.
Consider using System.Linq, eg...
string myString = "ADCBCBBBADEBCCBADBAACDCCBEDCBACCFEABBCBBBCCEAABCBB";
int countOfAs = myString.Count(x => x == 'A');
//Result: 9

I need to find the number of characters that are present in every line, within a List:
So, if for example, the string is
Ajdahnfj
Jnbafdbn
Jadnjadg
a,j,d,n are common for each line. Therefore the answer is 4.
No case sensitive is required
Regards
Here's a high level description of what I would do:
Make a collection of characters
initialize it to represent all of the characters in the first line
for each other line,
for each character in the collection, check if it's in that line. if it isn't then remove it from the list
return the resulting collection of characters
