Question
C# programming Chapter 14 question 1 Any help with input, output and comments of any sort would be very helpful.
**Chapter 14: Files and Streams** ### Exercises #### Programming Exercises 1. **DirectoryInformation Program**: Create a program named **DirectoryInformation** that allows users to continuously enter directory names until they type "end." If the directory name exists, display a list of the files in it; otherwise, display a message indicating the directory does not exist. Create as many test directories and files as needed to test your program. 2. **FileComparison Program**: Create a program named **FileComparison** that compares two files. First, use a text editor like Notepad to save your favorite movie quote. Next, copy the file contents and paste them into a word processor like Word. Then, write the file-comparison application that displays the sizes of the two files as well as the ratio of their sizes to each other. To discover a file’s size, you can create a `System.IO.FileInfo` object using statements such as: ```csharp FileInfo fileInfo = new FileInfo(FILE_NAME); size = fileInfo.Length; ``` 3. **ShowFileInfo Project**: Using Visual Studio, create a project named **ShowFileInfo** that contains a Form similar to the one in Figure 14-38. Specify a directory on your system, and when the Form loads, list the files the directory contains in a `ListBox`. Allow the user to click a file name, and then display the file’s creation date and time. Each time the user selects a new filename, update the creation date display. Create as many files as necessary to test your program. **Diagram Explanation**: - The image shows a screenshot of a Windows Form labeled "File Info." - It includes a section where users can "Select a file:" from a list. - Below the list, there is a section labeled "File information:" which displays the "Creation time:" followed by the date and time. In the image, the date and time shown are "2/25/2017 9:09:13 AM." - This setup helps users to select files and view their details in a clear, organized manner.
