DirectoryInfo Constructor (String^)

.NET Framework (current version)

Initializes a new instance of the DirectoryInfo class on the specified path.

Namespace: System.IO
Assembly: mscorlib (in mscorlib.dll)

Syntax

public:
DirectoryInfo(
	String^ path
)

Parameters

path: Type: System::String^
A string specifying the path on which to create the DirectoryInfo.

Exceptions

Exception	Condition
ArgumentNullException	path is null.
SecurityException	The caller does not have the required permission.
ArgumentException	path contains invalid characters such as ", <, >, or \|.
PathTooLongException	The specified path, file name, or both exceed the system-defined maximum length. For example, on Windows-based platforms, paths must be less than 248 characters, and file names must be less than 260 characters. The specified path, file name, or both are too long.

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.

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.

C++

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." );
   }

}
