Question

我的服务器上有MS Office。

如何判断它是否是我服务器上安装的32位或64位版本的Office 2013？

我需要使用C＃Code获取此信息。

Answer 1

关于获取32位或64位版本的Office 2013 C＃代码是：

   private Nullable<bool> IsOffice64Bit(string RegistryPrefix, string OfficeVersionNo)
    {
        Nullable<bool> isOffice64Bit = null;
        string Bitness = GetRegKey64(HKEY_LOCAL_MACHINE, RegistryPrefix + OfficeVersionNo + "\\Outlook", "Bitness");
        if (Bitness == "x86")
            isOffice64Bit = false;
        else if ((Bitness == "x64"))
            isOffice64Bit = true;
        return isOffice64Bit;
    }

调用示例：

Nullable<bool> isOffice64Bit = IsOffice64Bit("SOFTWARE\\Microsoft\\Office\\", OfficeVersionNo);
                if (isOffice64Bit == null)
                    isOffice64Bit = IsOffice64Bit("SOFTWARE\\Wow6432Node\\Microsoft\\Office\\", OfficeVersionNo);
                if (isOffice64Bit.HasValue && isOffice64Bit.Value)
                    InstalledOfficeVersion += " (64 bit)";
                else if (isOffice64Bit.HasValue && !isOffice64Bit.Value)
                    InstalledOfficeVersion += " (32 bit)";
                else
                {
                    InstalledOfficeVersion += " (Unknown bit)";
                }

    }
}

调用示例：

static void Main(string[] args)
{
    String OfficeVersion = new VersionFinder().GetOfficeVersion();
    Console.WriteLine("OfficeVersion: " + OfficeVersion);
    Console.ReadLine();
}

查看MSDN讨论here 以编程方式打开Word文档。他们用代码示例讨论了不同的方法

如何知道我的服务器中安装了哪个版本的Office 2013; 32位还是64位？
