ISet<T>.IsSubsetOf(IEnumerable<T>) 方法
定义
确定一个集是否为指定集合的子集。Determines whether a set is a subset of a specified collection.
public:
bool IsSubsetOf(System::Collections::Generic::IEnumerable<T> ^ other);
public bool IsSubsetOf (System.Collections.Generic.IEnumerable<T> other);
abstract member IsSubsetOf : seq<'T> -> bool
Public Function IsSubsetOf (other As IEnumerable(Of T)) As Boolean
参数
- other
- IEnumerable<T>
要与当前集进行比较的集合。The collection to compare to the current set.
返回
如果当前集是 other
的子集,则为 true
;否则为 false
。true
if the current set is a subset of other
; otherwise, false
.
例外
other
为 null
。other
is null
.
注解
如果 other
包含与当前集相同的元素,则当前集仍被视为另一个的子集。If other
contains the same elements as the current set, the current set is still considered a subset of other.
false
如果当前集包含不在中的元素,此方法将始终返回 other
。This method always returns false
if the current set has elements that are not in other
.
