How to create a system restore point programmatically?

Question

I'm looking for a way to create a system restore point with the current date and time by pressing a button. I've tried searching the web for a simple way to do this but I haven't found one yet.

I found this code snippet from: http://msdn.microsoft.com/en-us/library/windows/desktop/aa378847%28v=vs.85%29.aspx but it is in VB and not C#, I tried converting it a bit but I don't think i'm doing a great job of translating it.

'CreateRestorePoint Method of the SystemRestore Class
'Creates a restore point. Specifies the beginning and 
'the ending of a set of changes so that System Restore 
'can create a restore point.This method is the 
'scriptable equivalent of the SRSetRestorePoint function.

Set Args = wscript.Arguments
If Args.Count() > 0 Then
    RpName = Args.item(0)
Else 
    RpName = "Vbscript"
End If

Set obj = GetObject("winmgmts:{impersonationLevel=impersonate}!root/default:SystemRestore")

If (obj.CreateRestorePoint(RpName, 0, 100)) = 0 Then
wscript.Echo "Success"
Else 
    wscript.Echo "Failed"
End If

Here's a VB.NET snippet to create a restore point (found here):

Dim restPoint = GetObject("winmgmts:\\.\root\default:Systemrestore")
If restPoint IsNot Nothing Then
     If restPoint.CreateRestorePoint("test restore point", 0, 100) = 0 Then
         MsgBox("Restore Point created successfully")
    Else
         MsgBox("Could not create restore point!")
     End If
End If

Should be easy to "translate" to C#.

And here's another snippet in C# taken from this question:

private void CreateRestorePoint(string description)
{
    ManagementScope oScope = new ManagementScope("\\\\localhost\\root\\default");
    ManagementPath oPath = new ManagementPath("SystemRestore");
    ObjectGetOptions oGetOp = new ObjectGetOptions();
    ManagementClass oProcess = new ManagementClass(oScope, oPath, oGetOp);

    ManagementBaseObject oInParams =
         oProcess.GetMethodParameters("CreateRestorePoint");
    oInParams["Description"] = description;
    oInParams["RestorePointType"] = 12; // MODIFY_SETTINGS
    oInParams["EventType"] = 100;

    ManagementBaseObject oOutParams =
         oProcess.InvokeMethod("CreateRestorePoint", oInParams, null); 
}

Late, but I improved the answer from M4N...

public static void CreateRestorePoint(string description, EventType eventType, RestorePointType restorePointType)
{
    var mScope = new ManagementScope("\\\\localhost\\root\\default");
    var mPath = new ManagementPath("SystemRestore");
    var options = new ObjectGetOptions();
    using (var mClass = new ManagementClass(mScope, mPath, options))
    using (var parameters = mClass.GetMethodParameters("CreateRestorePoint"))
    {
        parameters["Description"] = description;
        parameters["EventType"] = (int)eventType;
        parameters["RestorePointType"] = (int)restorePointType;
        mClass.InvokeMethod("CreateRestorePoint", parameters, null);
    }
}

Example:

CreateRestorePoint("Example Restore Point", EventType.BeginSystemChange, RestorePointType.ModifySettings);
