I want to read text file skipping white space in asp.net with c#. I am reading the text file using stream reader.

Code is as below:

C#

using (StreamReader sr = new StreamReader(CSVFilePathName))
{
	while (!sr.EndOfStream)
	{
		if (sr != null)
		{
		   
			strData = File.ReadLines(CSVFilePathName).ElementAt(lineno).Split(',');
		}
	
	}
}

What I have tried:

Code is as below:
<pre> using (StreamReader sr = new StreamReader(CSVFilePathName))
                {
                    while (!sr.EndOfStream)
                    {
                                                
                        if (sr != null)
                        {
                           
                            strData = File.ReadLines(CSVFilePathName).ElementAt(lineno).Split(',');
}

What is the problem?

Other than opening the file for reading twice, and the infinite loop caused by never advancing the StreamReader? :)

Try

C#

using (StreamReader sr = new StreamReader(CSVFilePathName))
{
   string line;
   while ((line = sr.ReadLine()) != null)
   {
      strData = line.Split(',');
      for (int i = 0; i < strData.Length; ++i)
      {
         strData[i] = strData[i].Trim();
      }
      // ...
   }
}
