c# – 我可以在窗口标题中指定productversion吗？

Version version = Assembly.GetExecutingAssembly().GetName().Version;

this.Text = "My Cool Product - Version " + version;

// or with a fancier formatting
this.Text = string.Format("My Cool Product - Version {0}.{1}.{2} Revision {3}",version.Major,version.Minor,version.Build,version.Revision);

您还可以从存储在注册表中的MSI信息中读取设置的版本.这最好基于您的设置指定的UpgradeCode来完成,因为UpgradeCode不应在版本之间更改.以下示例程序演示了如何获取属于特定UpgradeCode的已安装版本1：

using System;
using System.Collections.Generic;
using System.Runtime.InteropServices;
using System.Text;

class Program
{
    [DllImport("msi.dll",CharSet = CharSet.Unicode)]
    static extern Int32 MsiGetProductInfo(string product,string property,[Out] StringBuilder valueBuf,ref Int32 len);

    [DllImport("msi.dll",CharSet = CharSet.Auto,SetLastError = true)]
    static extern Int32 MsiEnumRelatedProducts(string strUpgradeCode,int reserved,int iIndex,StringBuilder sbProductCode);

    static void Main(string[] args)
    {
        List<string> installedVersions = 
            GetInstalledVersions("{169C1A82-2A82-490B-8A9A-7AB7E4C7DEFE}");

        foreach (var item in installedVersions)
        {
            Console.WriteLine(item);
        }
    }

    static List<string> GetInstalledVersions(string upgradeCode)
    {
        List<string> result = new List<string>();
        StringBuilder sbProductCode = new StringBuilder(39);
        int iIdx = 0;
        while (
            0 == MsiEnumRelatedProducts(upgradeCode,iIdx++,sbProductCode))
        {
            Int32 len = 512;
            StringBuilder sbVersion = new StringBuilder(len);

            MsiGetProductInfo(sbProductCode.ToString(),"VersionString",sbVersion,ref len);

            result.Add(sbVersion.ToString());
        }
        return result;
    }
}

1请注意,可能会并行安装一个产品的多个版本.在极少数情况下,您将获得包含所有已安装版本的列表.
