Question

它是setupproject中的安装程序类，位于winform项目中。直到现在我确实有任何错误消息，它只是没有被调用。 RunInstallerAttribute设置为true。

唯一剩下的就是＆＃34;主要的空白＆＃34;，但我无法说出来，因为这是winformproject的neede。

Answer 1

最可能的原因是您没有在安装项目中将程序集添加为自定义操作，因为您没有提到这样做。

Answer 2

现在有效。我创建了那些“CommonAppDataFolder”，它似乎是c＃项目所需要的。多年前我用vb.net proejct制作它，不记得它是需要的。它需要安装应用程序，当然还有那些特殊权利，但安装程序的调用并不依赖于它。

最后我必须在“提交”中使用“使用（处理流程=新流程（））”来使用部分。无论我把什么放在-filename-和 -argument-，它总是抛出错误， - 它找不到文件夹“C / Program86 / ... .myApp.exe”。

当我发现这个使用部件时，我非常高兴，以为我现在已经离开了关闭最后的安装窗口“安装完成”。我总是要手动关闭这个窗口。

提交程序现在看起来像这样：

  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();          
        }
    }
