Open Ext4 file system.
//Get the file system
var fs = ExtFileSystem.Open(disk.Parititions[0]);
Sample code to open a file for read
//Open a file for read
var file = fs.OpenFile("/etc/shells", FileMode.Open, FileAccess.Read);
//Check the file length
var filelen = file.Length;
var buf = new byte[filelen];
//Read the file content
var count = file.Read(buf, 0, (int)filelen);
file.Close();
var content = Encoding.Default.GetString(buf);
Console.WriteLine(content);
Sample code for listing all files in a folder
//List all files in /etc folder
foreach (var file in fs.GetFiles("/etc", "*", SearchOption.AllDirectories))
{
Console.WriteLine(file);
}
Sample code for file creation
//Open a file for write
var file = fs.OpenFile("/etc/test", FileMode.Create, FileAccess.Write);
var hello = "Hello World";
var buf = Encoding.ASCII.GetBytes(hello);
//Write to file
file.Write(buf, 0, buf.Length);
file.Close();
