如何在C#方法中使用引用 [英] How to use reference in a c# method

问题描述

valid = ValidStageTransition(currentStageId, stageTransId, endReasonId,out preverify,out _list, out currentCSE,out ste)

我希望该方法基于ID来执行某些操作吗?它已经编写了代码.现在，我添加了两个变量_list和bool preverify.因为我想将内容添加到列表中.但它抱怨像

错误1 ValidStageTransition(int，int，int，bool，out System.Collections.Generic.Dictionary< string，string>，CaseStageEntity，Apption.CMS.LLBL.CHRC.EntityClasses.StageTransitionEntity)的最佳重载方法匹配''有一些无效的参数

错误2错误2不应使用关键字"out"传递参数"4".

I want that method to do some thing based on the id right?. Its already written code. Now I added the two variables _list and bool preverify. Because i want to add things to the list right. but it complains like

Error 1 The best overloaded method match for ValidStageTransition(int, int, int, bool, out System.Collections.Generic.Dictionary<string,string>, out CaseStageEntity, out Apption.CMS.LLBL.CHRC.EntityClasses.StageTransitionEntity)'' has some invalid arguments

error 2 Error 2 Argument ''4'' should not be passed with the ''out'' keyword

推荐答案

没有看到ValidStageTransition的实际方法签名，我想preverify不应该作为out参数传递，所以应该代替:

Without seeing the actual method signature for ValidStageTransition, I guess that preverify shouldn''t be passed as an out parameter, so instead of:

valid = ValidStageTransition(currentStageId, stageTransId, endReasonId,out preverify,out _list, out currentCSE,out ste)

您会写:

You''d write:

valid = ValidStageTransition(currentStageId, stageTransId, endReasonId, preverify, out _list, out currentCSE, out ste);

看看第二个错误，这就是解决问题的方法.

错误2错误2参数"4"不应与关键字"out"一起传递"

您需要删除"preverify"参数上的out关键字.

Look at the second error, it is how you resolve your problem.

"error 2 Error 2 Argument ''4'' should not be passed with the ''out'' keyword"

You need to remove the out keyword on the "preverify" argument.
