How to extract email id from a string without using regex

[indiedev91]

I am trying to learn string manipulation and want to extract email ids from strings

For example: “Hello there, this is my email address sagarrawl7764@gmail.com, please send me the document”

How do I extract the email without using regex or any predefine functionalities similar to regex?

If you are not using Regex
then fallow these steps.
1- Split string with space value. It will break your string and all the words will go in in string type array.
2-loop over string array.
3- use string. contains over each iteration and check that its contains "@gamail.com, @outlook.com, and so on.

Note: Its work in case of general case, email can be from different domain. Its not reliable than Regex. Regex is perfect

Hello @indiedev91 ,
Try this method it may help for you

Split(YourString," ")

You ca use the split string and loop it using for each loop , you can split each string.
Within loop , use if condition for isolate the string contains “@” “.”

item.ToString.Contains("@") And item.ToString.Contains(".")

KIndly refer this flow of XAML file.

the regex is only easy way and dynamic also if you go with string manipulation you cant get efficient

^[1]+@([\w-]+.)+[\w-]{2,4}$

this following regex you can use for email

---

1. \w-. ↩︎

Hi,

FYI, more strict approach:

validMailCharacters = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789!#$%&’*+-/=?^_`{|}~."
validDomainCharacters = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789-."

Then check if valid character as address and domain before/after @ character.
