Answer 1

Look like you want to split by fixed size.

So use yourString.Substring(0, 3);

Answer 2

splitArray = Regex.Split(subjectString, @"(?<=\p{N})(?=\p{L})");

will work in C# to split in positions between a number (\p{N}) and a letter (\p{L}).

If you also want to split between a letter and a number, use

splitArray = Regex.Split(subjectString, @"(?<=\p{L})(?=\p{N})|(?<=\p{N})(?=\p{L})");

however, that splits your example too much.

Answer 3

You can start with:

string filename = "123Prefix1pics.zip"
string part1 = filename.Substring(0, 3);
string part2 = filename.Substring(3, 7);
string part3 = filename.Substring(10, 4);

You can also note String.Split() needs a separator argument, like an ; or ,. As you don't have any separator, you can try two approaches:

• Make sure all your filenames have same format; this way, you can to use Substring() to break your strings
• You can identify a more general pattern, as "numbers, 7 characters plus 4 more characters" and to use a regular expression. This is a more advanced solution and can lead to maintenance problems;

I recommend you to stick with first option.

Answer 4

You only want to split that one string? Too easy!

string filename = "123Prefix1pics.zip"
string part1 = "123"
string part2 = "Prefix1"
string part3 = "pics.zip"

Ok this is a joke, but it gives the right answer. Unless you generalise your splitting rule, or provide further examples, we can only guess.

You may be asking to make a string break after a numeral, but again I'm only guessing.
