Jak programowo utworzyć punkt przywracania systemu?

Question

Szukam sposobu, aby utworzyć punkt przywracania systemu z bieżącą datą i godziną, naciskając przycisk. Próbowałem przeszukać sieć w prosty sposób to zrobić, ale jeszcze nie znalazłem.

Znalazłem ten fragment kodu z: http://msdn.microsoft.com/en-us/library/windows/desktop/aa378847%28v=vs.85%29.aspx, ale to jest w VB, a nie C#, próbowałem trochę go przekonwertować, ale nie sądzę, że wykonuję świetną robotę tłumaczenia tego.

'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 

Answer 1

Oto urywek VB.NET, aby utworzyć punkt przywracania (znajdujący 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 

powinien być łatwy do "przełożenia" na C#.

A oto kolejny fragment kodu w języku C# wzięte z 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); 
} 

Answer 2

var restPoint = GetObject(@"winmgmts:\\.\root\default:Systemrestore"); 
if(restPoint!=null) 
{ 
    if(restPoint.CreateRestorePoint("", 0, 100) == 0) 
    { 
     //do something 
    } 
    else 
    { 
     //do something 
    } 
}

późno, ale poprawiło odpowiedź od M4N ...

/// </exception> 
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); 
    } 
} 

Przykład:

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