![]() Instead, you make sure to dispose the stream object, and that will force buffer to be flushed before closing the stream. However, you normally do not flush the stream yourself but just let its internal mechanisms choose the best moment to do that. When you're working with file streams, you can flush their content explicitly using the StreamWriter.Flush() method - that is useful if you want to debug code and wish to see how far it has gone writing the data. File streams are definitely buffered, because it would be very inefficient to push each separate piece of data to the IO immediately. On a more elaborate level, streams that may cause performance loss are normally buffered. Writer.WriteLine(string.Join("\n", value)) You should dispose the stream writer and it will push everything out to disk: using (StreamWriter writer = new StreamWriter(fileName, false)) // <- this is the change Similarly, if you export a string array using PowerShell, the CSV will. Rather, defines Select as an extension method on IEnumerable, of which List is an example of.There are two types of files that can be handled in python, normal text files and binary files (written in binary language, 0s, and 1s). You see, List never has Select as a method. Video Python provides inbuilt functions for creating, writing, and reading files.The last line you write should use the Write method instead so that you don't have an empty line at the end. It may happen that the buffer was not flushed to the disk. CSV files are plain text files that store tabular data in a structured format. Try (and of course youll need assembly, but presumably you already have that). 1 Answer Sorted by: 0 First of all: debug your code and you'll find the problem yourself :) Issue is the use of the WriteLine method. So if any of you guys can help me with this problem that would be great because it seems like such a small problem but I can't figure it out for the life of me. static void writeCSV(List> aQuestion, List aAnswer)Ĭonsole.Write("Enter the file path for where you would like to export the exam to: ") Ĭonsole.WriteLine("File ", fileName, ioe.Message) Method 2: Write list to file in using Write function in Python. This is just my initialized nested list in case its needed. Method 1: Writing a list to a file line by line in Python using print. I went and did it on a separate test program to mock my problem and it worked on that program but when I moved the code over it would still not export anything. I am trying to export the strings in a nested list to a txt or csv file of the users choice and everything seems to be working but when I actually go to check the file after I have exported it the file is absolutely blank.
