ImmutableSortedDictionary<TKey,TValue>.Builder.TryGetValue(TKey, TValue) ImmutableSortedDictionary<TKey,TValue>.Builder.TryGetValue(TKey, TValue) ImmutableSortedDictionary<TKey,TValue>.Builder.TryGetValue(TKey, TValue) ImmutableSortedDictionary<TKey,TValue>.Builder.TryGetValue(TKey, TValue) Method

定义

获取与指定键关联的值。Gets the value associated with the specified key.

public:
 virtual bool TryGetValue(TKey key, [Runtime::InteropServices::Out] TValue % value);
public bool TryGetValue (TKey key, out TValue value);
abstract member TryGetValue : 'Key * 'Value -> bool
override this.TryGetValue : 'Key * 'Value -> bool
Public Function TryGetValue (key As TKey, ByRef value As TValue) As Boolean

参数

key
TKey TKey TKey TKey

将检索其值的键。The key whose value will be retrieved.

value
TValue TValue TValue TValue

当此方法返回时,如果找到该键,则包含与指定的键相关联的值;否则将包含 value 参数的类型默认值。When this method returns, contains the value associated with the specified key, if the key is found; otherwise, contains the default value for the type of the value parameter. 此参数未经初始化即被传递。This parameter is passed uninitialized.

返回

如果实现字典的对象包含具有指定键的元素,则为 true;否则为 falsetrue if the object that implements the dictionary contains an element with the specified key; otherwise, false.
