Definition
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Initializes a new instance of the DirectoryInfo class on the specified path.
public:
DirectoryInfo(System::String ^ path);public DirectoryInfo (string path);new System.IO.DirectoryInfo : string -> System.IO.DirectoryInfoPublic Sub New (path As String)Parameters
- path
- String
A string specifying the path on which to create the DirectoryInfo.
Exceptions
path is null.
The caller does not have the required permission.
.NET Framework and .NET Core versions older than 2.1: path contains invalid characters such as ", <, >, or |.
The specified path, file name, or both exceed the system-defined maximum length.
Examples
The following example uses this constructor to create the specified directory and subdirectory, and demonstrates that a directory that contains subdirectories cannot be deleted.
using namespace System;
using namespace System::IO;
int main()
{
// Specify the directories you want to manipulate.
DirectoryInfo^ di1 = gcnew DirectoryInfo( "c:\\MyDir" );
DirectoryInfo^ di2 = gcnew DirectoryInfo( "c:\\MyDir\\temp" );
try
{
// Create the directories.
di1->Create();
di2->Create();
// This operation will not be allowed because there are subdirectories.
Console::WriteLine( "I am about to attempt to delete {0}.", di1->Name );
di1->Delete();
Console::WriteLine( "The Delete operation was successful, which was unexpected." );
}
catch ( Exception^ )
{
Console::WriteLine( "The Delete operation failed as expected." );
}
}
using System;
using System.IO;
class Test
{
public static void Main()
{
// Specify the directories you want to manipulate.
DirectoryInfo di1 = new DirectoryInfo(@"c:\MyDir");
DirectoryInfo di2 = new DirectoryInfo(@"c:\MyDir\temp");
try
{
// Create the directories.
di1.Create();
di2.Create();
// This operation will not be allowed because there are subdirectories.
Console.WriteLine("I am about to attempt to delete {0}.", di1.Name);
di1.Delete();
Console.WriteLine("The Delete operation was successful, which was unexpected.");
}
catch (Exception)
{
Console.WriteLine("The Delete operation failed as expected.");
}
finally {}
}
}
open System.IO
// Specify the directories you want to manipulate.
let di1 = DirectoryInfo @"c:\MyDir"
let di2 = DirectoryInfo @"c:\MyDir\temp"
try
// Create the directories.
di1.Create()
di2.Create()
// This operation will not be allowed because there are subdirectories.
printfn $"I am about to attempt to delete {di1.Name}."
di1.Delete()
printfn "The Delete operation was successful, which was unexpected."
with _ ->
printfn "The Delete operation failed as expected."
Imports System.IO
Public Class Test
Public Shared Sub Main()
' Specify the directories you want to manipulate.
Dim di1 As DirectoryInfo = New DirectoryInfo("c:\MyDir")
Dim di2 As DirectoryInfo = New DirectoryInfo("c:\MyDir\temp")
Try
' Create the directories.
di1.Create()
di2.Create()
' This operation will not be allowed because there are subdirectories.
Console.WriteLine("I am about to attempt to delete {0}.", di1.Name)
di1.Delete()
Console.WriteLine("The Delete operation was successful, which was unexpected.")
Catch e As Exception
Console.WriteLine("The Delete operation failed as expected.")
End Try
End Sub
End Class
Remarks
This constructor does not check if a directory exists. This constructor is a placeholder for a string that is used to access the disk in subsequent operations.
The path parameter can be a file name, including a file on a Universal Naming Convention (UNC) share.
Caution
When you compile a set of characters with a particular cultural setting and retrieve those same characters with a different cultural setting, the characters might not be interpretable, and could cause an exception to be thrown.
