Read file data and display as text?

How do you want to present the data retrieved from the file?
What do you mean by form based? Can you give an example of what you have in mind?

To read a file, you use the StreamReader class.

string path = @"c:\temp\MyTest.txt";
try
{

if (File.Exists(path))
{

File.Delete(path);

}

using (StreamWriter sw = new StreamWriter(path))
{

sw.WriteLine("This");
sw.WriteLine("is some text");
sw.WriteLine("to test");
sw.WriteLine("Reading");

}


using (StreamReader sr = new StreamReader(path))
{

while (sr.Peek() >= 0)
{

Console.WriteLine(sr.ReadLine());

}

}

}
