Regular expression for getting any letter, symbol, number from 1 to 100 maxlength.

Question

As you can read in the tittle i need a regular expression for getting any letter, symbol, number from 1 to 100 maxlength (any text posible). Can someone provide that for me and maybe a good link to understand how it works. Thank you.

Answer 1

To match any text possible of maxlength 100 you can use:

.{1,100}

to even match newlines you can use:

[\d\D]{1,100}

Notes:

• . : A metachar that matches anything but a newline.
• {1,100}: min of 1 and max of 100 of the previous pattern
• []: the char class
• \d: any digit
• \D: any non-digit
• [\d\D]: any char

Answer 2

You should be able to piece it together from here:

here's the MSDN start page for regex:

Answer 3

I've found decent reference here for years. It's pretty generic & aimed at getting you to use their tools, but it's still a good reference.

Answer 4

If I understand you correctly you don't really need a regular expression to do this.

var test = "test";
var result = test.Substring(0, test.Length<100 ? test.Length : 100);
