You can try. But it's very processor/time intensive and even when you find a string that looks like an email address and has the correct MD5 hash, it may still not be the original address.
But you can do better than "nothing", which appears to be what most people are advocating.
Obtain a huge list of email addresses somewhere, and see if any of them match your hashes.
Look into oclHashcat. You can get it to test only strings that look like plausible email addresses. Email addresses are notorious for having much valid variation, but most will look like "asciichars@some_known_email_provider". Where the "asciichars" part is likely to contain words/names plus digits, underscores and dots. So don't use brute force, be smart. Use dictionaries of words+names and patterns.
1.in my Winform a make a remote call to the process and ask him to give me the list of all printers installed.
2. show the output in a lisbox for exemple.
We can abstract the question to "how do I get data from PC1 to PC2". The recommendation would be to look into WCF, but any type of exchange-mechanism would do- there's examples on communicating using sockets, but it'd even be possible using simple files.
Are the computers on the same LAN? If yes, I'd go for a simple socket
i would like to execute this code on a remote computer and get the data back to my winform.
Then you will need to write something to do that communication, or use an existing solution
You could also adapt the console-example to suit your needs, hence the link. If that's too much trouble, then you'd have to map a network-drive from the server, and use a batch-file to write the result to a file on that network-share. E.g.;
You're probably doing something wrong. I just tried it and had no trouble at all. Xml is perfectly capable of storing the text and giving it back.
You would need to show us the code you are using to determine what's wrong. Whatever the problem is, Replace isn't the best solution. Even if you think Replace is "good enough" for the particular program you're working on, it is not a good general solution and finding a better one will help you become a better developer.
P.S. What you posted will not produce well-formed XML if the user enters characters that aren't allowed. Try something like:
