Re: Creating a file with C# - C# Discussion Boards

14-Dec-03 5:38

Please search the comments for this forum. I just gave some advice to one person a few days ago about this. Basically, it's not very easy at all on C# but I gave some function reference that you should know and understand. The tips are there, but you have to figure out the solution. Besides, obviously, this is a homework question and we don't answer those in this - or any other - forum on CP. We'll give you tips and help if you're having a specific problem though.

It's just not right, and you won't learn anything by being given the answer.

I think there needs to be a message added to this board advising people to search the message board before posting and also trying msdn or google.

There is a saying: "You can lead a horse to water, but you can't make him drink."

You're assuming people will take the time to read it. For example, people still post programming questions in the Lounge even though there is a statement above the threads that indicates 'no programming questions'.

I dont know how basic this is but I am trying to create a file using a C# program.

Basicly I want a program that when you run it creates a text file that has on it a list of users.. Just like Console.WriteLine("Hello!") I want to put "Hello!" in a text file. Is this possible, if so -- please help Smile | :)

Thanks alot

There are a myriad of different ways to write to a text file, take a look at the System.IO Namespace[^], in particular the TextWriter class if you are just starting out. Smile | :)

There are quite a few ways of creating files. Here's an easy one:

Using System.IO;<br />
<br />
string path = @"C:\MyTextFile.txt";<br />
StreamWriter writer = new StreamWriter(path, true);<br />
writer.WriteLine("Howdy!");<br />
writer.Close();

This appends text to the file if it already exists or creates a new one if it doesn't. There are many other options if you need more fine-grained control over the file's behavior. Check out the System.IO namespace for more info on them.

Here I am. Love me.

try this as the first line in Main:

Console.SetOut( File.CreateText("console.log") );

Now everything goes to that file Smile | :)

Hi everyone,

I want to do something like XMLSpy or may tools like DreamweaverMX.

1) When you type this:

Before: (ignore the "")
========
"<"MyCompany">" //then the xml editor will automatically add the

After:
=======
"<"MyCompany">" "<"/MyCompany">"

I just want to do a very simple xml editor for c#. And at the end, save it into a xml file. I had been coding xml in notepad, and it is very troublesome.

I am not sure what areas i need to research in. Is there any tutorial on this or any source code, which i can refer to?

Any help, please?

Thanks.

Regards,
Chua Wen Ching :p

we are a small component company and a bit short on time , so we are always interested in people making samples with our controls.

if the project is not indended to be opensource you can get a license for free for our
syntaxbox (http://www.compona.com/wikiengine/WikiPageViewer.ascx?id=5[^])

supposing we get the right to publish the editor as a sample on our website.

Hi there,

Thanks for the url.

I am looking to how to do that, not using any component.

I just want to write a xml editor, so i can save up money and code xml much easier.

Any help, on areas which i can achieve the thing i want, please?

Thanks.

Heath Stewart13-Dec-03 6:35

Save money by using notepad, gvim, emacs, or some other vanilla text editor! If your typing skills are good enough, such "helpful" features are, IMO, actually just hinderances.

Are there any other requirements on what type of projects would qualify for this? Do they have to be freeware type projects or can it be a program that we might possibly sell?

what we are looking for is sample applications for our users , code samples using our free controls.
so we are not looking for huge binary demos of any sort , just easy to follow code samples.

I started to write my own and I found this on the net for FREE. http://architag.com/xray/ I use it all the time and find it very useful. If you still want to pursue developing your own I would enjoy the chance to work on an open source project if you need help.

Yeah, thanks for the link again.

I want to develop for myself. Anything that is written with c# and work with .net framework 1.1?

Just wonder, intellisense is something free to download and add into my system or what? Just assume i write a xml editor which i require intellisense.

Any help? Thanks.

I wrote an article for Windows Developer Journal on an XML wrapper in C#, with a friend called 'Matt Cole' ( google his name and mine to find it ) and the code came with a simple editor that does what you want, albiet in a brute force manner.

why im always getting a format exception when am tryin to convert a string to int using Convert.ToInt32() ??
however, the string only contains "5" .

thanx

Heath Stewart13-Dec-03 6:33

13-Dec-03 6:33

It should work (and does work in all other cases), so it begs the question: are you sure the string only contains "5" (by debugging your code and checking the string going into Convert.ToInt32), or do you only think it does? Remember that strings are immutable, so that if you originally had a string like "asdf5" and called someString.Remove(0, 4), it doesn't modify the original string but returns a new one instead (which you could assign to the same variable if you wanted).

heres my code.

<br />
nLevels = Convert.ToInt32(Levels.ToString(),16);<br />

where Levels is a textbox and contains a number !

is there any errors ?

thanx for reply

Try
nLevels = Convert.ToInt32(Levels.Text, 10);

I've never tried a TextBox.ToString() but I suspect it won't give you what you want. Also the 16 you've got in your line of code tells it to expect a Hexadecimal value rather than a decimal value. Are you sure that is what you wanted also?

Right, he definitely wants 10 for the radix. Also, System.Windows.Forms.TextBox.ToString always returns the Type, "System.Windows.Forms.TextBox", as do most classes (well, their own Type, which is inherited functionality from Object.ToString).
