String Replacement for "\0" ?

Question

_{Thursday, July 16, 2009 4:28 PM}

I  am receiving a text file that when viewed looks like it has blank lines when in reality the ReadLine() method returns a long string of "\0\0\0......".  I am trying to explore this file and get rid of these lines.  The Code is provided but it doesn't get rid of the \0's .   I have also tried Replace(\0,"") and  Replace(" ", "").

using (StreamReader reader = new StreamReader("C:\CSharp\Test\Deploy\"+filename+".txt"))

{

string linedata;

while ((linedata = reader.ReadLine()) != null)

{

linedata = linedata.Trim();

//Get rid of blank chars???

linedata.Replace(

"\0", "");

if (linedata.Length > 0)

{

datastrings.Add(linedata);

}

}

}

You're not reassigning lineData.  Remember, strings are immutable:

You have:

lineData.Replace("\0", "");

Should be:

lineData = lineData.Replace("\0", "");
