File Pointer in StreamReader

If you are reading from file using StreamReader by using string fileContent = sr.ReadToEnd();

and now if you will try to read it again using while ((line = sr.ReadLine()) != null)  for the same object, then you will not get any single word as file pointer is on end of file due to sr.ReadToEnd();

StreamReader sr = new StreamReader(fullFilePath);

if (sr != null)

{

string fileContent = sr.ReadToEnd();

if (fileContent.Contains(",") || fileContent.Contains("-"))

{

     

StringBuilder sbZipRadius = new StringBuilder();

string line = string.Empty;

//Read file line by line

while ((line = sr.ReadLine()) != null)

{

//if ',' exists in the line,it will be replace by '-'

line = line.Replace(',', '-');

}

}

//Close the file

sr.Close();

sr.Dispose();

}
