So, let's say there is :
MinimumPasswordAge = 4
I want to replace the 4, except the 4 will be a random number.
Or, how can i remove 1-2 characters after
MinimimPasswordAge =
BTW, this is all in a text file.

There are many many ways to do this. However, here is a regex example
var input = "MinimumPasswordAge = 4";
var result = Regex.Replace(input, @"(?<=MinimumPasswordAge = )\d+", "345");
Console.WriteLine(result);
Output
NumValue = 345
Note :This is assuming you know how to read all the text from the text file, and subsiquently write to one using E.g. File.ReadAllText
/ File.ReadLines
methods
Updated from Eric J's worthy comment
Use this pattern for white space tolerance
(?<=MinimumPasswordAge\s?=\s?)\d+
