示例

下面的代码示例演示如何调用 DirectoryNotFoundException 构造函数。

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

注解

此构造函数将 Exception.Message 新实例的属性初始化为系统提供的消息，该消息描述错误，例如“找不到指定的目录”。此消息将考虑当前系统区域性。

新 Exception.InnerException 实例的属性初始化为 null.

new System.IO.DirectoryNotFoundException : string * Exception -> System.IO.DirectoryNotFoundException

Public Sub New (message As String, innerException As Exception)

参数

message: String

解释异常原因的错误消息。

innerException: Exception

是当前异常原因的异常。如果未 innerExceptionnull 参数，则会在处理内部异常的 catch 块中引发当前异常。

注解

作为上一个异常的直接结果引发的异常应包括对 InnerException 属性中上一个异常的引用。 InnerException 属性返回传入构造函数的相同值，或者如果 null 属性未向构造函数提供内部异常值，则返回 InnerException。

下表显示了 DirectoryNotFoundException实例的初始属性值。
