从安装程序运行的可执行文件中获取MSI安装程序文件的名称

以下示例展示了如何通过安装程序内运行的可执行文件获取MSI安装程序文件的名称。

using Microsoft.Deployment.WindowsInstaller;

//获取当前安装程序的上下文
var context = new InstallContext(null, null);

//获取安装程序的所有安装信息
var installer = new Installer();
var session = installer.OpenPackage("<path_to_msi_file>", false);
var summaryInformation = session.SummaryInformation;

//从可执行文件中获取安装程序名称
var executablePath = context.Parameters["CustomActionData"];
var executableInfo = new System.IO.FileInfo(executablePath);
var msiName = System.IO.Path.GetFileNameWithoutExtension(summaryInformation.Property[1]);

//将名称打印到控制台
Console.WriteLine("The name of the MSI installer file is {0}.msi", msiName);

需要在安装程序中创建一个自定义操作，使得可执行文件能够接收包含安装程序名称的参数。例如：

<CustomAction Id="SetExecutableParameter" BinaryKey="CustomActions" DllEntry="SetExecutableParameter" Execute="immediate" Return="check" />
<InstallExecuteSequence>
    <Custom Action="SetExecutableParameter" Before="RunExecutable" />
    <Custom Action="RunExecutable" Before="InstallFinalize" />
</InstallExecuteSequence>

将以下代码添加到自定义操作中以设置参数：

using Microsoft.Deployment.WindowsInstaller;

public static ActionResult SetExecutableParameter(Session session)
{
    var installer = new Installer();
    var executeSequenceTable = installer.OpenExecuteSequenceDatabase("<path_to_msi_file>");
    var msiName = executeSequenceTable.ExecuteProperties["ProductCode"];
    session["CustomActionData"] = string.Format("{0} {1}", "<path_to_executable_file>", msiName);
    return ActionResult.Success;
}
