Hello,

I am new to C# and I am having some problems with an program that I have written using from code snippets from other websites. My source file has 6000+ rows of data. I want the program to search each line within the source file. When it finds a row that contains "_DS_TIME=": 1) I want to split the line into an array, 2) locate and convert the 4th and 5th segments of that array to and INT32, 3) I then want to add 86400 to those values, 4) followed by creating a new string that contains the same content as the old row, but replacing the 4th and 5th values with the new values (old value + 86400), 5) then I want to write this new line to a different text file.

If the loop does not find the "_DS_TIME=" within the row, then I write the entire row to the new text file with no changes.

When I run this program, it cuts off several rows of data that are in the source file, but not in the new text file.

Thanks

newline = exploded[0] + ',' + exploded[1] + ',' + exploded[2] + ',' + starttime + ',' + endtime + ',' + exploded[5];
writer.WriteLine(newline);

writer.WriteLine(line);

}
}

After your loop, you'll need to flush the writer with: writer.Flush();
Also, don't forget to Close() the writer.
