Win7 上的 VS2010，未調用安裝程序中的安裝程序類

Question

它是 setupproject 中的一個安裝程序類，它位於 winform 項目中。 直到現在我沒有任何錯誤消息，只是沒有被調用。 RunInstallerAttribute 設置為 true。

唯一剩下的是“主要空白”，但我不能說，因為 winform 項目需要它。

這是整個代碼：

Answer 1

最可能的原因是您沒有在安裝項目中將程序集添加為自定義操作，因為您沒有提到這樣做。

Answer 2

它現在有效。 我創建了那些“CommonAppDataFolder”，在 ac# 項目中似乎需要它。 幾年前我用 vb.net proejct 制作它，不記得需要它。 它需要安裝應用程序，當然具有這些特殊權限，但安裝程序的調用並不依賴於它。

最后，我必須在“Commit”中取出使用部分“using (Process process = new Process())”。 因為無論我對 -filename- 和 -argument- 設置什么，它總是會拋出一個錯誤， - 它無法找到文件夾“C/Program86/....myApp.exe”。

當我發現這個使用部分時，我真的很高興，以為我現在還剩下什么來關閉最終的安裝窗口“安裝完成”。 我總是不得不手動關閉這個窗口。

Commit 過程現在看起來像這樣：

  public override void Commit(IDictionary savedState)
    {
        string strPath = "";
        var myProcess = new Process();

        try
        {
            base.Commit(savedState);

            strPath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData), "Test");          
            strPath = Path.Combine(strPath, "myApp.exe");          
            myProcess.StartInfo.FileName = strPath;
            myProcess.StartInfo.CreateNoWindow = false;
            myProcess.Start();
            myProcess.WaitForExit(500);
            myProcess.Close();
            myProcess = null;         
        }          

        catch (Exception ex)
        {
            MessageBox.Show("public override void Commit  " + ex.ToString());
            Application.Exit();          
        }
    }
