using (StreamReader sr = new StreamReader("file.txt"))
{
string line;
while ((line = sr.ReadLine()) != null)
{
Console.WriteLine(line);
}
}
using (StreamReader sr = new StreamReader("file.txt"))
{
int c;
while ((c = sr.Read()) != -1)
{
Console.Write((char)c);
}
}
using (StreamReader sr = new StreamReader("file.txt"))
{
string content = sr.ReadToEnd();
Console.WriteLine(content);
}
using (StreamReader sr = new StreamReader("file.txt"))
{
while (sr.Peek() >= 0)
{
int c = sr.Read();
Console.Write((char)c);
}
}
using (StreamReader sr = new StreamReader("file.txt", Encoding.UTF8))
{
string line;
while ((line = sr.ReadLine()) != null)
{
Console.WriteLine(line);
}
}
