範例

以下程式碼範例示範如何呼叫建 DirectoryNotFoundException 構子。

using System;
using System.IO;

class Program
{

    static void Main(string[] args)
    {
        try
        {

            //  Specify a directory name that does not exist for this demo.
            string dir = @"c:\78fe9lk";

            // If this directory does not exist, a DirectoryNotFoundException is thrown
            // when attempting to set the current directory.
            Directory.SetCurrentDirectory(dir);
        }
        catch (DirectoryNotFoundException dirEx)
        {
            // Let the user know that the directory did not exist.
            Console.WriteLine("Directory not found: " + dirEx.Message);
        }
    }
}
Imports System.IO

Module Module1
    Sub Main()
        Try

            ' Specify a directory name that does not exist for this demo.
            Dim dir As String = "c:\78fe9lk"

            ' If this directory does not exist, a DirectoryNotFoundException is thrown
            ' when attempting to set the current directory.
            Directory.SetCurrentDirectory(dir)

        Catch ex As System.IO.DirectoryNotFoundException

            ' Let the user know that the directory did not exist.
            Console.WriteLine("Directory not found: " + ex.Message)
        End Try
    End Sub
End Module

備註

此建構子會將新實例的屬性初始 Exception.Message 化為系統提供的訊息,描述錯誤,例如「找不到指定目錄」。此訊息考量了當前系統文化。

Exception.InnerException新實例的屬性初始化為 null

初始化一個新的類別實例 DirectoryNotFoundException ,訊息字串設為 , message HRESULT 設為 COR_E_DIRECTORYNOTFOUND。

public:
 DirectoryNotFoundException(System::String ^ message);
public DirectoryNotFoundException(string message);
public DirectoryNotFoundException(string? message);
new System.IO.DirectoryNotFoundException : string -> System.IO.DirectoryNotFoundException
Public Sub New (message As String)

參數

message
String

String A,描述錯誤。 內容 message 是為了讓人類理解。 此建構器的呼叫者必須確保此字串已在目前系統文化中本地化。

備註

此建構子會使用初始messageException.Message新實例的屬性。

Exception.InnerException新實例的屬性初始化為 null

Protected Sub New (info As SerializationInfo, context As StreamingContext)

參數

info
SerializationInfo

SerializationInfo 個 保留了關於被拋出例外的序列化物件資料。

context
StreamingContext

the that StreamingContext 包含了關於來源或目的地的上下文資訊。

初始化類別的新實例 DirectoryNotFoundException ,並附上指定的錯誤訊息及導致該異常的內部例外的參考。

public:
 DirectoryNotFoundException(System::String ^ message, Exception ^ innerException);
public DirectoryNotFoundException(string message, Exception innerException);
public DirectoryNotFoundException(string? message, Exception? innerException);
new System.IO.DirectoryNotFoundException : string * Exception -> System.IO.DirectoryNotFoundException
Public Sub New (message As String, innerException As Exception)

參數

message
String

錯誤訊息解釋了例外原因。

innerException
Exception

該例外即為當前例外的原因。 若 innerException 參數不 null為 ,則在處理內部異常的區塊中提出 catch 當前例外。

備註

因先前例外直接拋出的例外,應包含對該屬性中 InnerException 先前例外的參考。 該 InnerException 屬性回傳與傳入建構子相同的值,或 null 若該 InnerException 性質未提供內部例外值給建構子。
