in the application development of A. NET/C-sharp programming, it is common to deal with files, and using the program to read large files is also a kind of file manipulation. So, what are the ways to read large files and convert them into byte array (byte array) in the. NET/C-sharp programming application development
use File.ReadAllBytes (.) Method, as follows:
byte[] file = System.IO.File.ReadAllBytes(fileName); static void ReadAllFile(string filename)
{
var content = File.ReadAllBytes(filename);
}
static async Task ReadAllFileAsync(string filename)
{
using (var file = File.OpenRead(filename))
{
using (var ms = new MemoryStream())
{
byte[] buff = new byte[file.Length];
await file.ReadAsync(buff, 0, (int)file.Length);
}
}
}
