推荐答案

您不必依赖自定义操作。

在Visual Studio 2008 Standard中有一个对话框可以使用

安装项目 - 属性 - 必需组件

除其他可能外，还有各种暴露.NET框架的版本和（在我的机器上）SQL Server Compact 3.5和SQL Server 2005 Express SP2（x86）。



所以我想，你会发现什么你需要那里。



请记住选择从应用程序的相同位置而不是来自经销商的网站或从这里：......单选按钮部分。否则，您的安装包中将没有包含该内容的数据，而只是链接。





这是代码讨论了将安装程序包包装在另一个应用程序资源中的可能性。实际上这是打开它。这是在包装器应用程序的运行时执行的。

You don't have to rely on custom actions for those.
In Visual Studio 2008 Standard there is a dialogue available using
Setup Project - Properties - Required Components
that, among other possibilities, exposes various versions of the .NET framework and (on my machine) SQL Server Compact 3.5 and SQL Server 2005 Express SP2 (x86).

So I guess, you will find what you need there.

Keep in mind to select "From same location as application" instead of "From distributor's website" or "From here: ..." in the radio button section. Otherwise there will be no data for that stuff packed in your setup package, but just links instead.


Here is code for the discussed possibility to wrap a setup package in another applications resources. Actually this is to unwrap it. This is executed during the wrapper applicaiton's runtime.

// Create a temporary directory to "extract" your setup stuff to
string tempPath = System.IO.Path.GetTempPath();
for (int tempIndex = 0; tempIndex < int.MaxValue; tempIndex++)
{
    string myTempPath = System.IO.Path.Combine(tempPath, tempIndex.ToString());
    if (
        System.IO.Directory.Exists(myTempPath)
        || System.IO.File.Exists(myTempPath)
    )
    {
        continue;
    }
    tempPath = myTempPath;
    break;
}

string setupExePath = null;

// Repeat what is in these braces
//   for all files and directories
//   that are necessary for your setup to work
{
    string fileName = System.IO.Path.Combine(tempPath, "Setup.exe");
    
    // Only for Setup.exe
    setupExePath = fileName;

    using (System.IO.MemoryStream stream = new System.IO.MemoryStream(Properties.Resources.WhatYouCalledYourSetupFileResource))
    {
        System.IO.File.WriteAllBytes(fileName, stream.ToArray());
    }
}

// Execute the original Setup.exe file.
System.Diagnostics.Process.Start(setupExePath);

// Delete the temporary stuff
System.IO.Directory.Delete(tempPath, true);
