You need to put all your content in a string and then replace what you need a and rewrite the text file with a StreamWriter.
StreamReader sr = null;
FileStream file = null;
string fileData = String.Empty;
file = new FileStream("test.txt", FileMode.Open, FileAccess.Read);
sr = new StreamReader(file, Encoding.UTF8);
string outputData = String.Empty;
string temp = String.Empty;
temp = sr.ReadLine();
if (temp != null)
temp = temp.Replace("the", "THE");
outputData += temp + "\n";
catch (Exception ex)
Console.WriteLine("An error occurred: " + ex.Message);
if (sr != null)
if (file != null)
You can also use the method ReadToEnd to read everything to one string and then use String.Replace method.
Depending on what you want to do you can also consider using regular expressions.
