#Project Description DiscUtils is a .NET library to read and write ISO files and Virtual Machine disk files (VHD, VDI, XVA, VMDK, etc). DiscUtils is developed in C# with no native code (or P/Invoke).
#Project Status Implementation of the ISO, UDF, FAT and NTFS file systems is now fairly stable. VHD, XVA, VMDK and VDI disk formats are implemented, as well as read/write Registry support. The library also includes a simple iSCSI initiator, for accessing disks via iSCSI and an NFS client implementation.
#How to use the Library Here's a few really simple examples.
###How to create a new ISO:
CDBuilder builder = new CDBuilder();
builder.UseJoliet = true;
builder.VolumeIdentifier = "A_SAMPLE_DISK";
builder.AddFile(@"Folder\Hello.txt", Encoding.ASCII.GetBytes("Hello World!"));
builder.Build(@"C:\temp\sample.iso");You can add files as byte arrays (shown above), as files from the Windows filesystem, or as a Stream. By using a different form of Build, you can get a Stream to the ISO file, rather than writing it to the Windows filesystem.
###How to extract a file from an ISO:
using (FileStream isoStream = File.Open(@"C:\temp\sample.iso"))
{
CDReader cd = new CDReader(isoStream, true);
Stream fileStream = cd.OpenFile(@"Folder\Hello.txt", FileMode.Open);
// Use fileStream...
}You can also browse through the directory hierarchy, starting at cd.Root.
###How to create a virtual hard disk:
long diskSize = 30 * 1024 * 1024; //30MB
using (Stream vhdStream = File.Create(@"C:\TEMP\mydisk.vhd"))
{
Disk disk = Disk.InitializeDynamic(vhdStream, diskSize);
BiosPartitionTable.Initialize(disk, WellKnownPartitionType.WindowsFat);
using (FatFileSystem fs = FatFileSystem.FormatPartition(disk, 0, null))
{
fs.CreateDirectory(@"TestDir\CHILD");
// do other things with the file system...
}
}As with ISOs, you can browse the file system, starting at fs.Root.
###How to create a virtual floppy disk:
using (FileStream fs = File.Create(@"myfloppy.vfd"))
{
using (FatFileSystem floppy = FatFileSystem.FormatFloppy(fs, FloppyDiskType.HighDensity, "MY FLOPPY "))
{
using (Stream s = floppy.OpenFile("foo.txt", FileMode.Create))
{
// Use stream...
}
}
}Again, start browsing the file system at floppy.Root.
