如何获取已安装软件产品的列表?

可以使用MSIAPI函数枚举所有已安装的产品。下面您将找到这样做的示例代码。

在我的代码中,我首先枚举所有产品,获取产品名称,如果它包含字符串“visualstudio”,我将检查 InstallLocation 财产。但是,并不总是设置此属性。我不确定这是否是要检查的正确属性,或者是否有另一个属性始终包含目标目录。也许是从 财产够你用吗?

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", SetLastError = true)]
    static extern int MsiEnumProducts(int iProductIndex, 
        StringBuilder lpProductBuf);

    static void Main(string[] args)
    {
        StringBuilder sbProductCode = new StringBuilder(39);
        int iIdx = 0;
        while (
            0 == MsiEnumProducts(iIdx++, sbProductCode))
        {
            Int32 productNameLen = 512;
            StringBuilder sbProductName = new StringBuilder(productNameLen);

            MsiGetProductInfo(sbProductCode.ToString(),
                "ProductName", sbProductName, ref productNameLen);

            if (sbProductName.ToString().Contains("Visual Studio"))
            {
                Int32 installDirLen = 1024;
                StringBuilder sbInstallDir = new StringBuilder(installDirLen);

                MsiGetProductInfo(sbProductCode.ToString(),
                    "InstallLocation", sbInstallDir, ref installDirLen);

                Console.WriteLine("ProductName {0}: {1}", 
                    sbProductName, sbInstallDir);
            }
        }
    }
}

你可以问警察 Installed applications classes Win32_Products 类表示Windows Installer安装的所有产品。例如,以下PS脚本将检索Windows Installer安装的本地计算机上安装的所有prodcuts:

Get-WmiObject -Class Win32_Product -ComputerName .

看到了吗 Working with Software Installations . 将PS查询移植到等效的WMI API(换句话说 Using WMI with the .NET Framework

如果您需要的所有程序都将其安装路径存储在注册表中,您可以使用以下方法: http://visualbasic.about.com/od/quicktips/qt/regprogpath.htm (我知道这是VB,但原理是一样的)。

我肯定有一种方法可以通过.NET获取程序列表,如果有些人不存储他们的安装路径(或者不清楚地进行安装),但我不知道。
