Question

我的代码发出此错误

'Net.Kniaz.AHP.AHPModel'不包含'AddCriteria'的定义，并且没有扩展方法'AddCriteria'接受类型'Net.Kniaz.AHP.AHPModel'的第一个参数可以找到（你错过了吗？） using指令或程序集引用？）

我不知道问题是什么。我回顾了几个类似的问题，但仍然找不到解决方案。

错误位于距离末端（模型）的行（5到13）行中。

Answer 1

您的班级AHPModel显然没有方法AddCriteria ...

Answer 2

您正在尝试使用一段不存在的代码。

 public class AHPModel
 {
 public AHPModel(int n, int m); 
 private GeneralMatrix _criteria;
 private GeneralMatrix _choiceMatrix;
 private GeneralMatrix _orderedCriteria;
 private GeneralMatrix _calculatedChoices;
 private int _ncriteria;
 private int _mchoice;
 private int _superDim;
/*private void AddCriteria(object o);*/ //<-ghost code
}

错误：不包含''的定义，也没有扩展方法
