Question

当我想创建一个新文件夹时，我没有任何问题我正在使用

Directory.CreateDirectory

现在我正在尝试从我的桌面获取所有图像文件，并且我想将所有图像移动到使用Directory.CreateDirectory创建的文件夹

我已经测试过.MoveTo 从这里

FileInfo file = new FileInfo(@"C:\Users\User\Desktop\test.txt");

到这里

file.MoveTo(@"C:\Users\User\Desktop\folder\test.txt");

这很完美。现在我想用我的dekstop

中的所有图像文件来做这件事

(Directory.CreateDirectory(@"C:\Users\User\Desktop\Images");)

我怎么能这样做？

Answer 1

从一个根文件夹获取具有特定扩展名的图像的示例代码：

        static void Main(string[] args)
      {
        // path to desktop
        var desktopPath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);

        //get file extentions by speciging the needed extentions
        var images = GetFilesByExtensions(new DirectoryInfo(desktopPath) ,".png", ".jpg", ".gif");

        // loop thrue the found images and it will copy it to a folder (make sure the folder exists otherwise filenot found exception) 
        foreach (var image in images)
        {
            // if you want to move it to another directory without creating a copy use:
            image.MoveTo(desktopPath + "\\folder\\" + image.Name);

            // if you want to move a copy of the image use this
            File.Copy(desktopPath + "\\"+ image.Name, desktopPath + "\\folder\\" + image.Name, true);
        }
      }

    public static IEnumerable<FileInfo> GetFilesByExtensions(DirectoryInfo dir, params string[] extensions)
    {
        if (extensions == null)
            throw new ArgumentNullException("extensions");

        var files = dir.EnumerateFiles();
        return files.Where(f => extensions.Contains(f.Extension));
    }

请试试这个：
您可以过滤特定目录中的文件，然后浏览搜索结果以移动每个文件，您可以修改搜索模式以匹配多种不同的图像文件格式

var files = Directory.GetFiles("PathToDirectory", "*.jpg");
    foreach (var fileFound in files)
    {
        //Move your files one by one here
        FileInfo file = new FileInfo(fileFound);
        file.MoveTo(@"C:\Users\User\Desktop\folder\" + file.Name);
    }

检查文件并创建文件夹并在C＃中移动文件
