如何在c#中删除Windows还原点？

using System;
using System.Runtime.InteropServices;

public class RestorePoint
{
    [DllImport("srrestoreptapi.dll", CharSet = CharSet.Auto, SetLastError = true)]
    public static extern int DeleteRestorePoint(int RestorePoint);

    public static void Delete(int restorePoint)
    {
        int result = DeleteRestorePoint(restorePoint);
        if (result != 0)
        {
            throw new ApplicationException("Error deleting restore point: " + result);
        }
    }
}

RestorePoint.Delete(12345);
