SortedSet<T>.TryGetValue(T, T) 方法

定義

搜尋指定值的資料集,並傳回所找到的相等值 (如果有的話)。Searches the set for a given value and returns the equal value it finds, if any.

public:
 bool TryGetValue(T equalValue, [Runtime::InteropServices::Out] T % actualValue);
public bool TryGetValue (T equalValue, out T actualValue);
member this.TryGetValue : 'T * 'T -> bool
Public Function TryGetValue (equalValue As T, ByRef actualValue As T) As Boolean

參數

equalValue
T

要搜尋的值。The value to search for.

actualValue
T

搜尋從集合中找到的值,或搜尋找不到相符項目時 T 的預設值。The value from the set that the search found, or the default value of T when the search yielded no match.

傳回

Boolean

指出搜尋是否成功的值。A value indicating whether the search was successful.

備註

當您想要重複使用先前儲存的參考,而不是 (新建立的參考時,這會很有用,因為它們的比較子函數指出它們相等,因此可能會發生更多的參考共用) 或查詢具有更完整資料的值。This can be useful when you want to reuse a previously stored reference instead of a newly constructed one (so that more sharing of references can occur) or to look up a value that has more complete data than the value you currently have, although their comparer functions indicate they are equal.
