 |
|
Ok, I'm having a file that I want to write some information to, but whenever I try to write to it with a string containing a filepath, the operation fails. Why is this? Any help is greatly appreciated.
Edit: Typo in title.

There is no error, the text is simply not written to the file. I didn't think the code would be needed considering the only interesting part is the call itself:
| Code: | StreamWriter someStream = new TextWriter(filename);
someStream.Write(theStringToWrite); |

I'm sorry if I mislead you, the code is actually like this : | Code: | using(StreamWriter someStream = new TextWriter(filename))
{
someStream.Write(theStringToWrite);
} |
Now correct me if I'm wrong, but doesn't this automatically close the stream after the closing bracket?
Edit: Typo.

| The object will be disposed but the Close method will not be called automatically, I belive.

Adding someStream.Close(); did not have any effect on the programs behaviour that I could see. I suspected this, considering it works fine when saving strings that does not contain filepaths.
Edit: Made a workaround for it. A part of the problem seems to have been that the default directory changes when using FileDialogs.

TextWriter is abstract you should get an error with that code.

When you use 'using' it will be closed automatically.
You can create a new instance of a streamwriter and write to the file.
| Code: | using (StreamWriter someStream = new StreamWriter(@"C:\test\lol.txt"))
{
someStream.Write("hijax");
} |
That will erase the file whenever it attempts to write to the file tho, if you want to append just send a bool like this :
| Code: | using (StreamWriter someStream = new StreamWriter(@"C:\test\lol.txt", true))
{
someStream.Write("jihad");
} |
