Hi,
i want to learn how to parse user input and check its validity in c#,
for example i want the user to input a specific format : "x,y to x,y" where x is a number and y is a number (entered by the user)
like : "1,4 to 3,8"
how do i do it?
i can do int.TryParse for each single number ( taking firs x then first y, and after, second x and second y)
but i want the user to input it all in one string and to get the x's and y's from it
how to do it
I won't get into the weeds here but this looks like the parsing job could be a few lines at most. I'd use the .Split method.
Read how at https://docs.microsoft.com/en-us/dotnet/csharp/how-to/parse-strings-using-split
Yes, they do mention CSV which is the style of input you asked about here.
To my mind asking for a long string with various parts from the user is asking for trouble. I would suggest asking for each element and parse it as it is entered.
