Get only numbers from a string in a file

Question

So, I have this file with a number that I want to use.

This line looks like this:

TimeAcquired=1433293042

I only want to use part of the number, but not the part that explains what it is.

So the output is:

1433293042

I just need numbers.

Is there a way to do this?

string setting=sr.ReadLine();
int start = setting.IndexOf('=');
setting = setting.Substring(start + 1, setting.Length - start);

A good approach to Extract Numbers Only

wherever they were found would be like this:

var MyNumbers = "TimeAcquired=1433293042".Where(x=> char.IsDigit(x)).ToArray();
var NumberString = new String(MyNumbers);

It's good when the FORMAT of the string is unknown. For example, you don't know how numbers were separated from letters.

you can do it with split () function like below

string theLineString="your string";
string[] collection=theLineString.Split('=');

so your string is split in two, i.e.

1) part before "=" 2) part after "=".

so you can access the parts by their index.

if you want to access numeric just do this

string answer=collection[1];

try

string t = "TimeAcquired=1433293042";
t= t.replace("TimeAcquired=",String.empty);

After a simple analysis.

int mrt= int.parse(t);

There is a very simple way to do this, and that is call Split()

in line and take the last part. For example, if you want to store it as a string:

var myValue = theLineString.Split('=').Last();

If you need it as an integer:

int myValue = 0;
var numberPart = theLineString.Split('=').Last();
int.TryParse(numberPart, out myValue);
