This code snippet helps to get the time when the Windows OS was last rebooted, using C# code.
It was required for me to get the last restart time for Windows in my program. But unfortunately I couldn't find any direct APIs from .NET. Also some articles suggested using the NetStat command and parsing the output as the available solution.
Using the Code
The following code snippet in C# will be helpful in getting the last restart time for Windows.
IntPtr bufPtr = IntPtr.Zero;
int val = NetStatisticsGet(null, "LanmanWorkstation", 0, 0, out bufPtr);
STAT_WORKSTATION_0 wks = new STAT_WORKSTATION_0();
if (val == 0)
wks = (STAT_WORKSTATION_0)Marshal.PtrToStructure(bufPtr, typeof(STAT_WORKSTATION_0));
DateTime aRebootTime = DateTime.FromFileTime(wks.StatisticsStartTime);
Points of Interest
The current code shows how to get the last restart time for the workstation. It is also possible get the restart time from the server.
