Detect the Visual Studio version inside a VSPackag

问题:

How can I check/detect which Visual Studio version is running under my VSPackage?

I cannot get from the registry because the computer could have several versions installed, so I guess there is an API that is able to get it.

Anybody knows how to get it from a managed Visual Studio package using C#?

回答1:

You could try to get version via automation DTE object. In MPF you could get it in this way:

EnvDTE.DTE dte = (EnvDTE.DTE)Package.GetGlobalService(typeof(EnvDTE.DTE));

There are some other related things to retrieve DTE object - via Project.DTE, also read this thread if you're getting null for DTE.

Then you can get the version by using DTE.Version property.

Also useful information could be found on Carlos Quintero (VS addin ninja) website HOWTO: Detect installed Visual Studio editions, packages or service packs

Finally I wrote a class to detect the Visual Studio version. Tested and working:

public static class VSVersion
{
    static readonly object mLock = new object();
    static Version mVsVersion;
    static Version mOsVersion;

    public static Version FullVersion
    {
        get
        {
            lock (mLock)
            {
                if (mVsVersion == null)
                {
                    string path = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "msenv.dll");

                    if (File.Exists(path))
                    {
                        FileVersionInfo fvi = FileVersionInfo.GetVersionInfo(path);

                        string verName = fvi.ProductVersion;

                        for (int i = 0; i < verName.Length; i++)
                        {
                            if (!char.IsDigit(verName, i) && verName[i] != '.')
                            {
                                verName = verName.Substring(0, i);
                                break;
                            }
                        }
                        mVsVersion = new Version(verName);
                    }
                    else
                        mVsVersion = new Version(0, 0); // Not running inside Visual Studio!
                }
            }

            return mVsVersion;
        }
    }

    public static Version OSVersion
    {
        get { return mOsVersion ?? (mOsVersion = Environment.OSVersion.Version); }
    }

    public static bool VS2012OrLater
    {
        get { return FullVersion >= new Version(11, 0); }
    }

    public static bool VS2010OrLater
    {
        get { return FullVersion >= new Version(10, 0); }
    }

    public static bool VS2008OrOlder
    {
        get { return FullVersion < new Version(9, 0); }
    }

    public static bool VS2005
    {
        get { return FullVersion.Major == 8; }
    }

    public static bool VS2008
    {
        get { return FullVersion.Major == 9; }
    }

    public static bool VS2010
    {
        get { return FullVersion.Major == 10; }
    }

    public static bool VS2012
    {
        get { return FullVersion.Major == 11; }
    }
}

I think the following code is better:

string version = ((EnvDTE.DTE) ServiceProvider.GlobalProvider.GetService(typeof(EnvDTE.DTE).GUID)).Version;
