finding variables and method names in a source code

[emyl21]

hello everybody i need to build a small program in C# that searches within a C source code (a txt file basically) for variables and method names and after that to replace them with something else. i can't do the first part. i've tried to do something but with no success. can you help me with some informations/suggestions? thank you in advance

You must know all the keywords that can come before a variable or method name, like int, string etc. You will also need to check if the word there for variable declaration and elsewhere. ie word string might come in a comment text and then you will end up editing the comment. All I can suggest is to make sure you know what I have written above. Then you can just take the very next word and replace it.

list the possible keywords, and try building a regular expression for them, since every line should end with ";" it might loosen writing the a regular expression for it, but it will be a lil tough. good luck
