C# API bindings

Description

The C# libvirt bindings are a class library. They use a Microsoft Visual Studio project architecture, and have been tested with Windows .NET, and Mono, on both Linux and Windows.

Compiling them produces LibvirtBindings.dll, which can be added as a .NET reference to any .NET project needing access to libvirt.

Requirements

These bindings depend upon the libvirt libraries being installed.

In the .NET case, this is libvirt-0.dll, produced from compiling libvirt for windows.

GIT source repository

The C# bindings source code is maintained in a git repository available on libvirt.org:

git clone git://libvirt.org/libvirt-csharp.git

They can also be browsed online:

Usage

The libvirt C# bindings class library exposes the Libvirt namespace. This namespace exposes all of the needed types (enum, struct), plus many classes exposing the libvirt API methods.

These classes are grouped into functional areas, with each class exposing libvirt methods related to that area.

For example, the libvirt methods related to connections, such as virConnectOpenAuth and virConnectNumOfDomains, are in the Connect class.
They are accessed as Connect.OpenAuth, and Connect.NumOfDomains respectively.

In the same manner, the other class name mappings are:

Name of libvirt function	C# class name
virDomain...	Domain
virEvent...	Event
virInterface...	Interface
virNetwork...	Network
virNode...	Node
virSecret...	Secret
virStoragePool...	StoragePool
virStorageVolume...	StorageVolume
virStream...	Stream

There are some additions as well:

There is a class named Library, exposing the virGetVersion and virInitialize methods
There is a class named Errors, exposing the error related methods. For example, virSetErrorFunc and virConnResetLastError.

Authors

The C# bindings are the work of Arnaud Champion <arnaud.champion AT devatom.fr>, based upon the previous work of Jaromír Červenka.

Test Configuration

Testing is performed using the following configurations:

Windows 7 (64 bits) / .Net 4
Windows 7 (64 bits) / Mono 2.6.7 (compiled in 32 bits)
Ubuntu 10.10 amd64 / Mono 2.6.7 (compiled in 64 bits)
