Question

I\'m having a problem when I use the method X509Store.Certificates.Find

public static X509Certificate2 FromStore(StoreName storeName, 
                  


        

Answer 1

I had the same Problem and solved it:

1. I copied the Fingerprint from mmc directly to VS. I compared the strings and didn't find any difference.

2. Checking the length with hash.length, there was a difference, 41 vs. 40.

There is an invisible Char added to the string by copying it out of mmc.

Solving:

1. copy the Fingerprint from mmc to Notepad.exe
2. copy this string again
3. paste to your code

It's working.
