How do i create a six digit sequence number in c# ?
Is there any other way than storing a string in the database like "000000" and later on incrementing it through the last inserted value ?

Use a plain old number as a sequence, this is what your DB will provide. If you want to display it with six digits, just call: yourNumber.ToString("D6")
(see docs)

Will the C# function Convert.ToInt32(text) convert different words to the same int? Any links or pushes in the right direction are appreciated!
P.S.
What about anagrams?
No, Convert.ToInt32(text) will just try to parse your text to an int, like:
Convert.ToInt32("032") will return 32 as int but
Convert.ToInt32("Brian") will throw an exception.
I assume that you want to have some kind of hashing, when you say "different words to the same int".
Try GetHashCode(). It will return the same value if you call it multiple times with the same value, for example:
"Brian".GetHashCode() will always return 1635321435

Please help
Assuming you list is a list of string:
var newList = yourList.Where(element => Regex.IsMatch(element, #"^[^a-z]", RegexOption.IgnoreCase);
It will give you a sublist of all the elements that doesn't start with a letter in the range a-z.

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

How to convert multi comma string to double?
Thanks for help.
From the looks of your question you actually have 10 numbers not 1. Use this code:
var nums = "1,2,3,4,5,6,7,8,9,10";
var digits = nums.Split(',').Select(r => Convert.ToDouble(r)).ToArray();
// the result will be an array of doubles, also this only works with .NET 3.5 or better.
Let me know if this works for you.
