DirectoryInfo Constructor
Assembly: mscorlib (in mscorlib.dll)
| Exception type | Condition |
|---|---|
| path is a null reference (Nothing in Visual Basic). |
|
| The caller does not have the required permission. |
|
| path contains invalid characters such as ", <, >, or |. |
|
| 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. |
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. |
The following table lists examples of other typical or related I/O tasks.

| Write to a text file. | |
| Read from a text file. | |
| Rename or move a directory. | |
| Delete a directory. | |
| Create a directory. | |

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 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 {} } }
import System.*;
import System.IO.*;
class Test
{
public static void main(String[] args)
{
// 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.get_Name());
di1.Delete();
Console.WriteLine("The Delete operation was successful, "
+ "which was unexpected.");
}
catch (System.Exception exp) {
Console.WriteLine("The Delete operation failed as expected.");
}
finally {
}
} //main
} //Test
