    Default merge 2 csv files

    Hi,

    any one can help me to solve this issue.

    Have 2 files File1.csv and file2.csv containing some values. Have to read both files and write unique values in to another file.
    in the new the there must be unique rows and not duplicate rows(2 files contain some rows same)
    What is the best approach for doing this?

    Welcome! Please read this topic to learn how to post code correctly and other useful info for new members.

    Read every line in each of the two files
    Store the data from the two files into one collection
    Sort the collection
    Locate and mark duplicate entries
    Write unmarked entries to the 3rd file

    I see. Since you began this thread to obtain code and not help coding, I'm closing it. Come back and start another when you have code - your own - and need help with it.
