将数组从php转换为asp.net c#和文件目录枚举

我有一个PHP脚本，我正试图将其转换为ASP.NET C#

以下是PHP：

<?php

/* Configuration Start */

$thumb_directory = 'img/thumbs';
$orig_directory = 'img/original';

$stage_width=600;   // How big is the area the images are scattered on
$stage_height=400;

/* Configuration end */

$allowed_types=array('jpg','jpeg','gif','png');
$file_parts=array();
$ext='';
$title='';
$i=0;

/* Opening the thumbnail directory and looping through all the thumbs: */

$dir_handle = @opendir($thumb_directory) or die("There is an error with your image directory!");

$i=1;
while ($file = readdir($dir_handle)) 
{
    /* Skipping the system files: */
    if($file=='.' || $file == '..') continue;

    $file_parts = explode('.',$file);
    $ext = strtolower(array_pop($file_parts));

    /* Using the file name (withouth the extension) as a image title: */
    $title = implode('.',$file_parts);
    $title = htmlspecialchars($title);

    /* If the file extension is allowed: */ 
    if(in_array($ext,$allowed_types))
    {
        /* Generating random values for the position and rotation: */
        $left=rand(0,$stage_width);
        $top=rand(0,400);
        $rot = rand(-40,40);

        if($top>$stage_height-130 && $left > $stage_width-230)
        {
            /* Prevent the images from hiding the drop box */
            $top-=120+130;
            $left-=230;
        }

        /* Outputting each image: */

        echo '
        <div id="pic-'.($i++).'" class="pic" style="top:'.$top.'px;left:'.$left.'px;background:url('.$thumb_directory.'/'.$file.') no-repeat 50% 50%; -moz-transform:rotate('.$rot.'deg); -webkit-transform:rotate('.$rot.'deg);">
        <a class="fancybox" rel="fncbx" href="'.$orig_directory.'/'.$file.'" target="_blank">'.$title.'</a>
        </div>';
    }
}

/* Closing the directory */
closedir($dir_handle);

?>

如何在数组中循环？有点困惑，因为直到读取目录后才填充数组。

您可以使用

System.IO.directory

的

GetFiles

方法（）来实现这一点

for (string file in System.IO.Directory.GetFiles(thumb_directory)) {
  Console.WriteLine(file);
}

值得一看

System.IO.Path

class（），因为它提供了一些很好的方法，比如

GetFileNameWithoutExtension（）

和

GetExtension（）

编辑：完全转换

    protected void Page_Load(object sender, EventArgs e) {
        /* Configuration Start */
        string thumb_directory = "img/thumbs";
        string orig_directory = "img/original";
        int stage_width = 600;
        int stage_height = 480;
        Random random = new Random();

        // array of allowed file type extensions
        string[] allowed_types = { "bmp", "gif", "png", "jpg", "jpeg", "doc", "xls" };

        /* Opening the thumbnail directory and looping through all the thumbs: */
        foreach (string file in Directory.GetFiles(thumb_directory)) {
            string title = Path.GetFileNameWithoutExtension(file);
            if (allowed_types.Contains(Path.GetExtension(file)) == true) {
                int left = random.Next(0, stage_width);
                int top = random.Next(0, 400);
                int rotation = random.Next(-40, -40);

                if ((top > stage_height - 130) && (left > stage_width - 230)) {
                    top -= 120 + 130;
                    left -= 230;
                }
            }
        }
    }

是的，还不错。已为您完成转换，但将详细信息输出到浏览器除外。这将取决于你是使用WebForms还是MVC。好吧，它实际上没有对你计算的图像路径/位置做任何有用的事情，但是是的。我建议您查看并移动实际的配置内容（例如路径）。并移动到使用符号常量`const int stage_width=600；“（计算中的值也是如此。）但希望你能理解。是的，我想是的..哇，你真的是个好人！我现在可以研究你提到的东西了。上帝保佑你！：）必须用这个来代替：if（allowed_types.Equals（Path.GetExtension（file））==true）as contains不起作用。

    protected void Page_Load(object sender, EventArgs e) {
        /* Configuration Start */
        string thumb_directory = "img/thumbs";
        string orig_directory = "img/original";
        int stage_width = 600;
        int stage_height = 480;
        Random random = new Random();

        // array of allowed file type extensions
        string[] allowed_types = { "bmp", "gif", "png", "jpg", "jpeg", "doc", "xls" };

        /* Opening the thumbnail directory and looping through all the thumbs: */
        foreach (string file in Directory.GetFiles(thumb_directory)) {
            string title = Path.GetFileNameWithoutExtension(file);
            if (allowed_types.Contains(Path.GetExtension(file)) == true) {
                int left = random.Next(0, stage_width);
                int top = random.Next(0, 400);
                int rotation = random.Next(-40, -40);

                if ((top > stage_height - 130) && (left > stage_width - 230)) {
                    top -= 120 + 130;
                    left -= 230;
                }
            }
        }
    }
