備註

當作業嘗試使用不存在於該集合中的索引鍵, 從集合中抓取專案時,就會擲回。KeyNotFoundExceptionA KeyNotFoundException is thrown when an operation attempts to retrieve an element from a collection using a key that does not exist in that collection.

KeyNotFoundException使用 HRESULT COR_E_KEYNOTFOUND, 其值為0x80131577。KeyNotFoundException uses the HRESULT COR_E_KEYNOTFOUND, which has the value 0x80131577.

如需KeyNotFoundException類別實例的初始屬性值清單, KeyNotFoundException請參閱函式。For a list of initial property values for an instance of the KeyNotFoundException class, see the KeyNotFoundException constructors.
