How to write to a text file in C#
The
FileStream object is used to write to a file. The Write method of FileStream
can be used to write to a file. It takes a byte array. The following code
snippet creates a FileStream object using the File.Open method that takes a
file name as its first parameter and then uses the Write method of the
FileStream to write it the file.
using (FileStream fs = File.Open(fileName, FileMode.Open,
FileAccess.Write, FileShare.None))
{
Byte[] info = new UTF8Encoding(true).GetBytes("Add more text");
fs.Write(info, 0, info.Length);
}
