</div>接口继承，然后覆盖IEquatable<T>函数。当我使用Equals比较班级的实例时，它总是会返回cellStyle1.Equals(cellStyle2) ...

我已经尝试过它似乎不起作用。这是我试过的：

false

我做错了什么？

Answer 1

您调用# dummy data df1 <- read.table(text = "x y z a 1 1 b 3 NA NA 5 0 f NA 1", header = TRUE) # result apply(combn(colnames(df1), 2), 2, function(i){ res <- df1[, i] res[complete.cases(res), ] }) # [[1]] # x y # 1 a 1 # 2 b 3 # # [[2]] # x z # 1 a 1 # 4 f 1 # # [[3]] # y z # 1 1 1 # 3 5 0方法继承自Equals而非您的实施方法。您应该覆盖基本System.Object方法，最好使用隐式接口实现（而不是显式），因此如果编译器可以解析此调用，则会直接调用您的方法（Equals和cellStyle1都是在编译时编译cellStyle2。）

Answer 2

您正在显式实现IEquatable<Cell_Style>，因此您需要在调用之前强制转换为该接口：

((IEquatable<Cell_Style>)cellStyle1).Equals(cellStyle2)

更简单的方法是将实施公开：

public bool Equals(Cell_Style other) { ... }

如果Equals的类型为cellStyle2，则会选择Cell_Style的正确重载。您还应覆盖object.Equals以致电Equals(Cell_Style)并实施GetHashCode。
