A character at the end of file? there should be a function to check the file pointer, but files don't have an EOF appended, unless this is a specific file format. ----- Original Message ----- From: "David Engebretson Jr." <d.engebretson@xxxxxxxxxxx>

There is a character at the end of the file... might be 0x20? Don't remember off hand, but I'll bet there's a table at the end of your book.Cheers, D----- Original Message ----- From: "Celia Rodriguez" <celia-rodriguez@xxxxxxxxxxxxx>To: <programmingblind@xxxxxxxxxxxxx> Sent: Sunday, May 09, 2010 7:50 AM Subject: RE: C# Writing to a fileHi again, Thank you for your suggestions.I was able to write and read to a file.

It is pretty much the same exceptthat it is an instance class, it does not require a security check every time it is called and can be made threqad safe me thinks.If you are justlogging errors or something that you don't care about performance with then the File class is the way to go since you will not have to instantiate theclass in your code but it will run slower.

Below is the MSDN Doc stuff I pulled from the File Class Definition that I thought might help. The complete document can be found at: http://msdn.microsoft.com/en-us/library/ms143356.aspx if you want to read up on the File Class. Here is the copied stuff for the CSharp version: Copy using System; using System.IO; using System.Text; class Test { public static void Main() { string path = @"c:\temp\MyTest.txt" ; // RtNote, notice the .txt file extension in the above file path // Also, note the use of the @ sign as Jamal identified in a prior post. // This text is added only once to the file. if (!File.Exists(path)) { // Create a file to write to. string createText = "Hello and Welcome" + Environment.NewLine; File.WriteAllText(path, createText); } // This text is always added, making the file longer over time // if it is not deleted. string appendText = "This is extra text" + Environment.NewLine; File.AppendAllText(path, appendText); // Open the file to read from. string readText = File.ReadAllText(path); Console.WriteLine(readText); } }----- Original Message ----- From: "Jamal Mazrui" <empower@xxxxxxxxx>To: <programmingblind@xxxxxxxxxxxxx> Cc: "Celia Rodriguez" <celia-rodriguez@xxxxxxxxxxxxx> Sent: Saturday, May 08, 2010 6:34 AM Subject: Re: C# Writing to a fileIn C#, you do not have to double the backslash characters if you precedethe string literal with the @ symbol. Just put that symbol immediately before the initial quote mark.
