QS: Using the System.IO in C#, Create a graphical application of your choice to demonstrate the use of READ and WRITE operations like we did in LAB#5. Be Creative.

Submit a Word Document with the Design and the Code.

For Reference:

Lab # 5: C# File Management Solution

Problem Description:

READ: Create a program to display all the contents of a text file on screen (note: you must use a StreamReader). The name of the file will be entered in the command line.

WRITE: Create a program to ask the user for several sentences until they just press Enter (empty sentence) and store them in a text file named "test.txt"

string fileName = Microsoft.VisualBasic.Interaction.InputBox("Enter the Name of the File", "File Name", "", 50, 100);

label1.Text = label1.Text + fileName;

StreamReader myFile;

try

{

myFile = File.OpenText(fileName);

string line = "";

do

{

line = myFile.ReadLine();

if (line != null)

}

} while (line != null);

}catch(IOException)

{

MessageBox.Show("File Does not Exit", "Error", MessageBoxButtons.OK, MessageBoxIcon.Stop);
