What is the use of Get,Set properties in c#

Would you read the documentation before asking such questions?
And programming is programming; it is not counting of number of "ways". This question doesn't mean anything certain, and, as a software developer, you are supposed to understand that, because logical thinking is one of the most important things. The topic is way too simple to discuss it. Why do you think that an answer quickly written specially for you should be better than thoroughly written documentation and manuals. Read them.
