如何以編程方式創建系統還原點？

Question

我正在尋找一種通過按下按鈕來創建系統還原點以及當前日期和時間的方法。我試過在網上搜索一個簡單的方法來做到這一點，但我還沒有找到。

我發現這個代碼片段來自：http://msdn.microsoft.com/en-us/library/windows/desktop/aa378847%28v=vs.85%29.aspx但它是在VB中，而不是C＃，我試着轉換它，但我不認爲我在翻譯它做得很好。

'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

這裏有一個VB.NET代碼段創建一個還原點（發現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 

應該很容易 「翻譯」 爲C＃。

下面是在C＃中的另一個片段從this question採取：

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 
    } 
}

晚了，但我提高了從M4N答案...

/// <summary> 
///  The type of event. For more information, see <see cref="CreateRestorePoint"/>. 
/// </summary> 
public enum EventType 
{ 
    /// <summary>

    ///  point. 
    ///  <para> 
    ///   Subsequent calls must use <see cref="EventType.EndNestedSystemChange"/>, not

    BeginNestedSystemChange = 0x66, 

    /// <summary>

}

public enum RestorePointType

    /// </summary> 
    ApplicationInstall = 0x0, 

    /// <summary>

    ApplicationUninstall = 0x1, 

    /// <summary>

    /// </summary> 
    CancelledOperation = 0xd, 

    /// <summary> 
    ///  A device driver has been installed. 
    /// </summary> 
    DeviceDriverInstall = 0xa, 

    /// <summary>

    /// </summary> 
    ModifySettings = 0xc 
} 

/// <summary>

/// </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); 
    } 
} 

例子：

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