如何将“设置”从Vb转换为C＃

Question

How to convert the following VB code to C# code?

Set atDIOAOIPIsReady = _
atDIOGObjRepos.InsertOutputObjectIfNew(sIPIsReadyID, atDIOAOIPIsReady)

My idea is :

atDIOAOIPIsReady -= atDIOGObjRepos.InsertOutputObjectIfNew(ref sIPIsReadyID,atDIOAOIPIsReady);

But it showed me the error as following:

1. The best overload method match for

    ActivVTools._AVTDIOFObjectRepository.InsetOutputObjectIfNew(ref string, ref ActivVTools._IAVTDIOObject) 

   has some invalid arguments.

2. Argument '1' must be passed with the 'ref' keyword

3. Argument '2' cannot convert from ActivVTools.AVTDIOActionObjectClass to ref ActivVTools._IAVTDIOObject

Answer 1

Based on the documentation (pdf) you need to first create an AVTDIOActionObjectClass object. In the sample they showed, they set the Description property which will not be necessary.

The SET keyword is VB6 and has been used to assign references to a variable. Nowadays with VB.NET this isn`t used/needed anymore.

The C# code would be (see the ref keyword for the second parameter):

AVTDIOActionObjectClass atDIOAOIPIsReady=new AVTDIOActionObjectClass ();
atDIOAOIPIsReady= atDIOGObjRepos.InsertOutputObjectIfNew(ref sIPIsReadyID, 
                  ref atDIOAOIPIsReady);

Answer 2

尝试这个：

atDIOAOIPIsReady = atDIOGObjRepos.InsertOutputObjectIfNew(ref sIPIsReadyID, atDIOAOIPIsReady);
