how to check operating system in c#..?
-
hello, I have developed an desktop application in C#.NET Framework(3.5). My client is using the application on different OS like(Xp, Seven, Vista). I have developed the app and did over all testing on XP. Now some features of app are not working on Seven and Vista for which i need to do some extra work. Is there any piece of code in c# by which i can check which operating system is installed and them my app according to that OS. Thanks in Advance, Asfand

Take a look at
System.Environment.OSVersion.System.Environment.OSVersion.Version.Majorwill return one of the following: 4 = Windows 95, 98, ME or NT 4.0 5 = Windows 2000, XP or 2003 Server 6 = Vista, Windows 7 or 2008 Server Then query theSystem.Environment.OSVersion.Version.MinorSee the following for detailed break down of version numbers of Windows OS.

You can use Environment.OSVersion to get the OperatingSystem back. From this you can determine whether or not it's a Vista+ system with a simple check:
public bool IsVistaOrHigher
{
get { return OSVersion.Version.Major >= 6);
}If the application can run in compatibility mode though, this is potentially unreliable. Another way to do this is to use a method that only exists in a Vista (or greater) OS to determine it. Here's another example that demonstrates it:
public bool IsVistaOrHigher
{
get
{
return IsVistaOrHigherHelper();
}
}private bool IsVistaOrHigherHelper()
{
IntPtr hModule = LoadLibrary("Kernel32.dll");
if (hModule != null)
{
IntPtr proc = GetProcAddress(hModule, "MoveFileTransactedA");
return proc.ToInt32() != 0;
}
return false;
}I used part of the Kernel Transaction Manager (KTM) to do this - you can use any new API to accomplish the same.

What you change depends on what your app is doing. If properly written, you shouldn't need to check the O/S version to modify the apps behavior.

Dave is absolutely right. First make sure you have to know which OS version your app is running on. Oftentimes people think they need to know while they really don't. A typical example would be the use of special folders, such as "My Documents", which seems to be located at different locations on different Windows versions. However there is a simple way to get that path without worrying about the OS version at all; that too is inside the Environment class. :)

While this is good advice, there are certain occassions where this check does count. Suppose you want to use the Kernel Transaction Manager, for instance. If your application runs on Vista+ it will work, but it won't on XP. You should be able to provide a graceful degrade mechanism at this point.

I fully agree, feature detection is part of, well, decent behavior. But it is Microsoft's duty to hide those tiny changes that don't bring much, and make things needlessly hard, and sometimes they do provide a solution, with people not always aware of it. :)

I think this code help you. RegistryKey KEY = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\Windows NT\CurrentVersion"); string version= KEY.GetValue("ProductName").ToString();

Very true, but I don't think the OP is using anything platform specific.

Call it an "educated guess".
