Directory.Exists() checks if the specified folder exists.

The Directory.Exists() method is used to check if a specific folder exists. It takes a string parameter indicating the folder’s path and returns a boolean value – true if the folder exists, false if it does not.

Here is a sample code:

using System;
using System.IO;

class Program
{
    static void Main()
    {
        string folderPath = @"C:\Temp"; // 指定文件夹路径
        bool folderExists = Directory.Exists(folderPath); // 使用Directory.Exists()判断文件夹是否存在

        if (folderExists)
        {
            Console.WriteLine("文件夹存在");
        }
        else
        {
            Console.WriteLine("文件夹不存在");
        }
    }
}

Note: When using Directory.Exists() to determine if a folder exists, you need to provide the full path of the folder.
