What is DirectoryInfo class in c#?

DirectoryInfo class in c# enables you to work with Directory. With Directory Info class You can create, delete, Move or enumerate a directory. You can also get info about any directory like creation time, last access time of a directory using the Directory info class.
The DirectoryInfo class accepts a single parameter that is either the full path or relative path of the directory.

DirectoryInfo d1 = new DirectoryInfo(@"c:\dirname");

where,, dirname is the name of your directory.

Some of the Important properties of the DirectoryInfo class are:

CreationTime: It is used to retrieve the creation time of the directory.
LastAccessTime: It is used to retrieve the last access time of the directory.
FullName: It is used to retrieve the fully qualified path of the directory.
Name: It is used to retrieve only the name of the folder without the path. For example, If your directory exists at D:\MyDoc\MyDir then this property will only return folder name i.e. MyDir.

Create Directory Example:

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace DirectoryInfoClass
{
class Program
{
static void Main(string[] args)
{
String sPath = @"D:\MyDir";
DirectoryInfo objDirInfo = new DirectoryInfo(sPath);
if (!objDirInfo.Exists)
{
objDirInfo.Create();
}
else
{
Console.WriteLine("Directory already exists");
}
Console.ReadKey();
}
}
}}

Move Directory Example:

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace DirectoryInfoClass
{
class Program
{
static void Main(string[] args)
{
String sSource = @"D:\MyDir";
String sDest = @"D:\NewDir";
DirectoryInfo objDirSource = new DirectoryInfo(sSource);
objDirSource.MoveTo(sDest);
{
Console.WriteLine("Directory Move Successfully");
}
Console.ReadKey();
}
}
}

Delete Directory Example:

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace DirectoryInfoClass
{
class Program
{
static void Main(string[] args)
{
String sSource = @"D:\NewDir";
DirectoryInfo objDirSource = new DirectoryInfo(sSource);
if (objDirSource.Exists)
{
objDirSource.Delete();
}
Console.ReadKey();
}
}
}

Get /Directory Details Example:

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace DirectoryInfoClass
{
class Program
{
static void Main(string[] args)
{
DirectoryInfo objDir = new DirectoryInfo(@"D:\newfile");
Console.WriteLine("Directory name is {0} ", objDir.Name);
Console.WriteLine("Directory name is {0} ", objDir.FullName);
Console.WriteLine("Directory exist : ", objDir.Exists);
Console.WriteLine("Directory root is {0} ", objDir.Root);
Console.WriteLine("Directory creation time is {0} ", objDir.CreationTime.ToLongTimeString());
Console.WriteLine("Directory Lastaccesstime is {0} ", objDir.LastAccessTime.ToLongDateString());
Console.WriteLine("Directory LastWriteTime is {0} ", objDir.LastWriteTime);
DirectoryInfo[] objNumberOfDir= objDir.GetDirectories()
Console.WriteLine("Number of Dorectory {0} ", objNumberOfDir.Length);
Console.ReadKey();
}
}
}
