此函数在编译的程序集中名为 IsProperSubset。 如果从 F# 以外的语言中访问函数,或通过反射访问成员,请使用此名称。示例下面的代码阐释了 Set.isProperSubset 函数的用法。F# 复制 let set1 = Set.ofList [ 1 .. 6 ] let set2 = Set.ofList [ 1 .. 5 ] let set3 = Set.ofList [ 1 .. 6 ]...
We say that A is a subset of B , denoted A\subseteq B , iff every element of A is also an element of B . We say that A is a proper subset of B , denoted A\subset B , if A\subseteq B and A\ne B . 这里有个有趣的remark: Because these definitions involve only the notions ...
public bool IsProperSubsetOf (System.Collections.Generic.IEnumerable<T> other); 参数 other IEnumerable<T> 要与当前的 SortedSet<T> 对象进行比较的集合。 返回 Boolean 如果SortedSet<T> 对象是 other 的真子集,则为 true;否则为 false。 实现 IsProperSubsetOf(IEnumerable<T>) IsProperSubsetOf(IEnum...
