c# 中文件和目录的基本操作
在本文中,我们将介绍如何创建、删除和重命名目录,以及如何删除和重命名文件。
创建目录
我们可以使用目录类中的 CreateDirectory() 方法创建目录。
c sharp . c sharp . c sharp . c sharp
// C# program to create a directory
using System;
using System.IO;
class Program {
// Main Method
static void Main(string[] args)
{
Console.WriteLine("Please enter a name for the new directory:");
string DirName = Console.ReadLine();
// Checking if string is empty or not
if (DirName != String.Empty)
{
// Creating the Directory
Directory.CreateDirectory(DirName);
// Checking Directory is created
// Successfully or not
if (Directory.Exists(DirName))
{
Console.WriteLine("The directory was created!");
Console.ReadKey();
}
}
}
}
输出:
您将在特定位置找到具有给定名称的目录。
重命名目录
c sharp . c sharp . c sharp . c sharp
using System;
using System.IO;
class GFG {
// Main Method
static void Main(string[] args)
{
Console.WriteLine("Please enter a name of the directory to renamed:");
string DirName = Console.ReadLine();
// checking directory exist or not
if (Directory.Exists(DirName))
{
Console.WriteLine("Please enter a new name for this directory:");
string newDirName = Console.ReadLine();
if (newDirName != String.Empty) {
// to rename directory
Directory.Move(DirName, newDirName);
// checking directory has
// been renamed or not
if (Directory.Exists(newDirName))
{
Console.WriteLine("The directory was renamed to " + newDirName);
Console.ReadKey();
}
}
}
}
}
输出:
您将在特定位置找到更新后的目录名称。没有所谓的重命名()方法,所以我们使用 Move()方法来重命名目录。移动和重命名是 C# 中相同的操作。
删除目录
c sharp . c sharp . c sharp . c sharp
using System;
using System.IO;
class GFG {
// Main Method
static void Main(string[] args)
{
Console.WriteLine("Enter the directory name you want to delete:");
string DirName = Console.ReadLine();
// Checking if Directory Exist or not
if (Directory.Exists(DirName))
{
// This will delete the
// Directory if it is empty
Directory.Delete(DirName);
// checking if directory if
// deleted successfully or not
if (Directory.Exists(DirName) == false)
Console.WriteLine("Directory deleted successfully...");
}
else
Console.WriteLine("Directory {0} does not exist!", DirName);
Console.ReadKey();
}
}
