Regex to match alphabets and other characters but not digits c#

Question

Hello,

I have a string as below in C# :

subject:practitioner.address-state

I have written the regex "^([A-Za-z]+)(:[A-Za-z]+)?.([A-Za-z]+)$" to match the above string but it fails as "address-state" has hyphen (-) in it.

The rest of the part before address-state works fine. Now the last part i.e address-state would have alphabets and/or other characters such as (-,/. etc). It cannot have any numeric value.

I need to modify the above regex to match this.

Regards,
Abdi

Try a new expression:

 ^(\p{L}+)(:\p{L}+)?\.(\p{L}+)(-(\p{L}+))*$

But, if you dislike non-Latin letters, you can use [A-Za-z] instead of \p{L}.
