If you want to write binary information into the stream, then use the BinaryWriter class in C#. You can find it under the System.IO namespace.
The following is the implementation of the BinaryWriter class −
static void WriteMe() {
using (BinaryWriter w = new BinaryWriter(File.Open("C:\\abc.txt", FileMode.Create))) {
w.Write(37.8);
w.Write("test”);
}
}
static void ReadMe() {
using (BinaryReader r = new BinaryReader(File.Open("C:\\abc.txt", FileMode.Open))) {
Console.WriteLine("Value : " + r.ReadDouble());
Console.WriteLine("Value : " + r.ReadString());
}
}Above, theBinaryWriter class opens a file and writes content into it −
static void WriteMe() {
using (BinaryWriter w = new BinaryWriter(File.Open("C:\\abc.txt", FileMode.Create))) {
w.Write(37.8);
w.Write("test");
}
}
