備註

此函式會Message將新實例的屬性初始化為系統提供的訊息, 以描述錯誤, 例如「指定的索引鍵不存在於字典中」。This constructor initializes the Message property of the new instance to a system-supplied message that describes the error, such as "The given key was not present in the dictionary." 此訊息會考量目前的系統文化特性。This message takes into account the current system culture.

屬性Property Value
InnerException null.null.
Message 當地語系化的錯誤訊息字串。The localized error message string.

KeyNotFoundException(String)

使用指定的錯誤訊息,初始化 KeyNotFoundException 類別的新執行個體。Initializes a new instance of the KeyNotFoundException class with the specified error message.

public:
 KeyNotFoundException(System::String ^ message);

new System.Collections.Generic.KeyNotFoundException : string -> System.Collections.Generic.KeyNotFoundException
Public Sub New (message As String)

參數

message
String

描述錯誤的訊息。The message that describes the error.

備註

message 參數的內容必須能讓人了解。The content of the message parameter is intended to be understood by humans. 這個建構函式的呼叫端必須確保這個字串已經被當地語系化 (為了目前系統的文化特性)。The caller of this constructor is required to ensure that this string has been localized for the current system culture.

KeyNotFoundException(SerializationInfo, StreamingContext)

使用序列化資料,初始化 KeyNotFoundException 類別的新執行個體。Initializes a new instance of the KeyNotFoundException class with serialized data.

protected:
 KeyNotFoundException(System::Runtime::Serialization::SerializationInfo ^ info, System::Runtime::Serialization::StreamingContext context);
protected KeyNotFoundException (System.Runtime.Serialization.SerializationInfo info, System.Runtime.Serialization.StreamingContext context);
new System.Collections.Generic.KeyNotFoundException : System.Runtime.Serialization.SerializationInfo * System.Runtime.Serialization.StreamingContext -> System.Collections.Generic.KeyNotFoundException
Protected Sub New (info As SerializationInfo, context As StreamingContext)

參數

info
SerializationInfo

SerializationInfo,包含所擲回之例外狀況的相關序列化物件資料。The SerializationInfo that holds the serialized object data about the exception being thrown.

context
StreamingContext

包含有關來源或目的端內容資訊的 StreamingContextThe StreamingContext that contains contextual information about the source or destination.

備註

進行還原序列化 (Deserialization) 期間會呼叫這個建構函式,以便重新構成經由資料流傳送的例外狀況物件。This constructor is called during deserialization to reconstitute the exception object transmitted over a stream. 如需詳細資訊,請參閱 < XML 和 SOAP 序列化For more information, see XML and SOAP Serialization.

KeyNotFoundException(String, Exception)

使用指定的錯誤訊息和造成這個例外狀況原因的內部例外狀況參考,初始化 KeyNotFoundException 類別的新執行個體。Initializes a new instance of the KeyNotFoundException class with the specified error message and a reference to the inner exception that is the cause of this exception.

public:
 KeyNotFoundException(System::String ^ message, Exception ^ innerException);
public KeyNotFoundException (string message, Exception innerException);
new System.Collections.Generic.KeyNotFoundException : string * Exception -> System.Collections.Generic.KeyNotFoundException
Public Sub New (message As String, innerException As Exception)

參數

message
String

解釋例外狀況原因的錯誤訊息。The error message that explains the reason for the exception.

innerException
Exception

做為目前例外狀況發生原因的例外狀況。The exception that is the cause of the current exception. 如果 innerException 參數不是 null,則目前的例外狀況會在處理內部例外的 catch 區塊中引發。If the innerException parameter is not null, the current exception is raised in a catch block that handles the inner exception.

備註

被擲回以做為前一個例外狀況直接結果的例外狀況,應該在 InnerException 屬性中包含對前一個例外狀況的參考。An exception that is thrown as a direct result of a previous exception should include a reference to the previous exception in the InnerException property. InnerException 屬性會傳回與傳入建構函式中相同的值;如果 null 屬性沒有提供內部例外值給建構函式,則傳回 InnerExceptionThe InnerException property returns the same value that is passed into the constructor, or null if the InnerException property does not supply the inner exception value to the constructor.
