Win7上的VS2010，安装程序中的安装程序类不叫

Question

它是setupproject中的安装程序类，它位于winform项目中。直到现在，我确实拥有任何errro消息，它只是不叫。 RunInstallerAttribute设置为true。

剩下的唯一东西就是“主要空白”，但我不能说出来，导致winformproject是neede。

这里是整个代码：

Answer 1

最可能的原因是你没有添加组件的安装项目自定义操作，因为你没有提到这样做。

Answer 2

它现在有效。我创建了那些“CommonAppDataFolder”，看起来是它在c＃项目中所需要的。几年前，我用vb.net proejct做了它，不记得它是需要的。它需要安装该应用程序，当然还有这些特权，但安装程序的调用并不取决于它。

And finallay我必须在“Commit”中使用部分“using（Process process = new Process（））”。原因不管我给-filename-和 -argument-，它总会抛出一个错误， - 它无法找到文件夹“C/Program86/... .myApp.exe”。

当我发现使用部分时，我非常高兴，因为我现在得到了什么来关闭最终安装窗口“安装完成”。我总是需要手动关闭这个窗口。

提交程序现在看起来是这样的：

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();   
     } 
    }
