.NET Framework 2.0 features on VS 2005.

[Paul Lemelle]

I am tyring to use the .NET Framework 2.0 with Visual Studio 2005, but
I cannot get the System.IO / class method File ReadAllText feature to
work. How can I get this to work with VS 2005?

Thanks,
Paul

In VB2005:

'Read in a file and split the lines by CrLf
Dim crlfs() as String = {ControlChars.CrLf}
Dim lines() as String = _
File.ReadAllText("c:\data.txt").Split(crlfs, StringSplitOptions.None)
Dim numOfLines = lines.Length

If you want more help, you will need to tell exactly what's
not working, and post your code.

I am using C#, and here is the code:

using system;
using system.IO;

namespace FileIO

Class File
{
public static void Main ()
{
string myfile = File.ReadAllText("myfile");
// I do not get the File.ReadAllText - I only get Equals, Main,
// & ReferenceEquals after File.
Console.Writeline(myfile);
}
}

The code fills because the compiler does not know what to do with the
File.ReadAllText method.

I tried this, and it worked fine. I think your problem is your file name
"myfile". My guess is that it can not find the file. Try a file with a
path, like "C:\Test.txt".

Also be sure you have "using System.IO;" at the top of your class.

And Writeline should be WriteLine. C# is case-sensitive.

Naming you class as "File" is a bad choice.

You code will not compile, since you also used "System.IO" name space, which
has a class called "File". You need to qualify the class "File" to
distinguish which namespace it belongs to:

string myfile=System.IO.File.ReadAllText(...) //If the ReadAllText is not
from your custom class

or

string myfile=FileIO.File.ReadAllText(...) //If your "File" class
defines the method with the same name.

I strongly recommend you name your namespace/class wisely.

hi Norman,

That was it - thanks.

using system;
using system.IO;

namespace FileIO

Class File
{
public static void Main ()
{
string myfile = File.ReadAllText("myfile");
// I do not get the File.ReadAllText - I only get Equals, Main,
// & ReferenceEquals after File.
Console.Writeline(myfile);
}
}

That's certainly not the code you had mostly working - it's really
helpful if you cut and paste the *actual* code in, rather than creating
a *similar* program which will fail for other reasons. Problems with
the above, *apart* from the collision of the "File" name:

1) Case of "system"
2) No braces after the namespace declaration
3) Case of class declaration
4) Case of the "l" in Writeline

In general, if you've already got a problem in your code, it makes it
hard for us to tell the problems which are *really* there compared with
typos when retyping the code unless you use cut and paste properly.
