C# DirectoryInfo Example
In the following example, we are creating a Program directory by specifying the directory path.
using System.IO;
namespace CSharpProgram
{
class Program
{
static void Main(string[] args)
{
// Provide directory name with complete location.
DirectoryInfo directory = new DirectoryInfo(@"E:\program");
try
{
// Check, directory exist or not.
if (directory.Exists)
{
Console.WriteLine("Directory already exist.");
return;
}
// Creating a new directory.
directory.Create();
Console.WriteLine("The directory is created successfully.");
}
catch (Exception e)
{
Console.WriteLine("Directory not created: {0}", e.ToString());
}
}
}
}
Output:
