C#使用WMI获取控制面板中安装的所有程序列表
WMI
全称Windows Management Instrumentation,Windows Management Instrumentation是Windows中用于提供共同的界面和对象模式以便访问有关操作系统、设备、应用程序和服务的管理信息。如果此服务被终止，多数基于 Windows 的软件将无法正常运行。如果此服务被禁用，任何依赖它的服务将无法启动。
WMI提供公用接口及对象模型，以存取有关操作系统、装置、应用程序及服务的管理信息。
新建窗体应用程序WindowsManagementDemo,将默认的Form1重命名为FormWMI,
添加引用System.Management,如下图:
窗体FormWMI设计器代码如下:
文件FormWMI.Designer.cs
cs
namespace WindowsManagementDemo
{
partial class FormWMI
{
/// <summary>
/// 必需的设计器变量。
/// </summary>
private System.ComponentModel.IContainer components = null;
/// <summary>
/// 清理所有正在使用的资源。
/// </summary>
/// <param name="disposing">如果应释放托管资源，为 true；否则为 false。</param>
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}
#region Windows 窗体设计器生成的代码
/// <summary>
/// 设计器支持所需的方法 - 不要修改
/// 使用代码编辑器修改此方法的内容。
/// </summary>

因读取程序遍历数据过多,这里使用等待任务await Task
cs

using System.Linq;
using System.Text;

public FormWMI()
{
InitializeComponent();
/*

}
this.BeginInvoke(new Action(() =>
{
if (rtxtMessage.TextLength >= 40960)
{
rtxtMessage.Clear();
}
rtxtMessage.AppendText($"{DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss.fff")}->{message}\n");
rtxtMessage.ScrollToCaret();
}));
}
private async void FormWMI_Load(object sender, EventArgs e)
{
await Task.Run(() =>
{
ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_Product");
ManagementObjectCollection managementCollection = searcher.Get();
DisplayMessage("累计个数：" + managementCollection.Count);
int sequence = 0;
int tempIndex = 0;
foreach (ManagementBaseObject install in managementCollection)
{
sequence++;
this.BeginInvoke(new Action(() =>
{
tempIndex++;
dgvWMI.Rows.Add(tempIndex, install["Name"], install["Vendor"], install["InstallDate"], install["InstallLocation"], install["Version"]);
}));
PropertyDataCollection Properties = install.Properties;
DisplayMessage($"【{sequence.ToString("D3")}】{install["Name"]}:属性键值对个数：{install.Properties.Count}");
foreach (PropertyData propertyData in Properties)
{
DisplayMessage($"\x20\x20Name:{propertyData.Name},Value:{propertyData.Value},Type:{propertyData.Type}");
}
}
});
}
}
}运行如图:
