Question

我正在寻找一种通过按下按钮来创建具有当前日期和时间的系统还原点的方法。我试过在网上搜索一个简单的方法，但我还没找到。

我发现这个代码片段来自：http://msdn.microsoft.com/en-us/library/windows/desktop/aa378847%28v=vs.85%29.aspx，但它是在VB而不是C＃中，我尝试将其转换一下，但我不认为我在翻译它方面做得很好。

'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

这是一个用于创建还原点的VB.NET代码段（找到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

应该很容易“翻译”为C＃。

这是C＃中另一个摘录自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); 
}

迟到了，但我改进了M4N的答案......

/// <summary>
///     The type of event. For more information, see <see cref="CreateRestorePoint"/>.
/// </summary>
public enum EventType
{
    /// <summary>
    ///     A system change has begun. A subsequent nested call does not create a new restore
    ///     point.
    ///     <para>
    ///         Subsequent calls must use <see cref="EventType.EndNestedSystemChange"/>, not
    ///         <see cref="EventType.EndSystemChange"/>.
    ///     </para>
    /// </summary>
    BeginNestedSystemChange = 0x66,

    /// <summary>

    /// </summary>
    BeginSystemChange = 0x64,

    /// <summary>
    ///     A system change has ended.
    /// </summary>
    EndNestedSystemChange = 0x67,

    /// <summary>

    /// </summary>
    EndSystemChange = 0x65
}

/// <summary>
///     The type of restore point. For more information, see <see cref="CreateRestorePoint"/>.
/// </summary>
public enum RestorePointType
{
    /// <summary>
    ///     An application has been installed.
    /// </summary>
    ApplicationInstall = 0x0,

    /// <summary>
    ///     An application has been uninstalled.
    /// </summary>
    ApplicationUninstall = 0x1,

    /// <summary>
    ///     An application needs to delete the restore point it created. For example, an
    ///     application would use this flag when a user cancels an installation. 
    /// </summary>
    CancelledOperation = 0xd,

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

    /// <summary>

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

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);
    }
}

示例：

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

Answer 3

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

如何以编程方式创建系统还原点？
