What is the difference between StreamWriter.Flush() and StreamWriter.Close()?

should help you out StreamWriter.Flush() can be called any time you need to clear the buffer, and the stream will remain open.
StreamWriter.Close() is for closing the stream, at which point the buffer is also flushed.
using (var writer = new StreamWriter("somefilepath.txt"))
{
   // write a bunch of stuff here
} // the streamwriter WILL be closed and flushed here, even if an exception is thrown.

I wish did fix the issue. I read in a text file using StreamReader. I want to write out this same text file EXCEPT its first 4 lines and its last 6 lines.
string[] fileLines = File.ReadAllLines(@"your file path"); 

var result = fileLines.Skip(4).Take(fileLines.Length - (4 + 6));

File.WriteAllLines(@"your output file path", result);

Because as said in the java doc :

it helps some times
When you create a wrapper around an inputstream/reader - performing close on the wrapper does a close on the wrapped object. So you do not need all those close calls.

Reading from BufferedReader throws exception as stream closed after creating a new BufferedReader

I hope this helps you . When the BufferedReader gets closed at the end of the try-with-resources block, System.in is also closed and it can't be reopened.
You should open the reader once and keep it open somewhere where you can use it until your program is finished.
