Problem with opening file and pathname

Hi All,

I'm new to the boards. I have a problem opening a file for reading. Here are snipets of code I am using.

Code:

 /// <summary> 
    /// Create a new reader for the given stream. 
    /// </summary> 
    /// <param name="s">The stream to read the CSV from.</param> 
    public CSVReader(Stream s) : this(s, null) { } 

    /// <summary> 
    /// Create a new reader for the given stream and encoding. 
    /// </summary> 
    /// <param name="s">The stream to read the CSV from.</param> 
    /// <param name="enc">The encoding used.</param> 
    public CSVReader(Stream s, Encoding enc) { 

      this.stream = s; 
      if (!s.CanRead) { 
        throw new CSVReaderException("Could not read the given CSV stream!"); 
      } 
      reader = (enc != null) ? new StreamReader(s, enc) : new StreamReader(s); 
    } 

    /// <summary> 
    /// Creates a new reader for the given text file path. 
    /// </summary> 
    /// <param name="filename">The name of the file to be read.</param> 
    public CSVReader(string filename) : this(filename, null) { } 

    /// <summary> 
    /// Creates a new reader for the given text file path and encoding. 
    /// </summary> 
    /// <param name="filename">The name of the file to be read.</param> 
    /// <param name="enc">The encoding used.</param> 
    public CSVReader(string filename, Encoding enc) 
      : this(new FileStream(filename, FileMode.Open), enc) { }

Here is where I am trying to open the file:

Code:

using ( CSVReader csv = new CSVReader(@"C:\Documents and Settings\testfile1.csv") )

Now, I want to be able to change the pathname so that my program can process multiple files (using a for loop).

ie:
"C:\Documents and Settings\testfile1.csv"
"C:\Documents and Settings\testfile2.csv"
"C:\Documents and Settings\testfile3.csv"
...


I tried loading the path into a string variable and using String.Concat( , ) to create the full path. However, I get errors from the '\' within the strings.

Does anyone know anyother way to accomplish what I am trying to do?

Thanks,
Steve

Or you could use C#.

Code:

string.Format(@"C:\folder\folder\filename{0}.txt",1);

Look at the MSDN docs on System.IO.Path, specifically System.IO.Path.Combine(string, string)

Don't reinvent the wheel or brute force things when there are already framework methods to do the work for you.
