c# – 在这个相对简单的程序中获得“内存不足”异常

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Drawing;

namespace SharpLibrary_MediaManager
{
    public class Picture:BaseFile
    {
        public int Height { get; set; }
        public int Width { get; set; }
        public Image Thumbnail { get; set; }

        /// <summary>
        /// Sets file information of an image from a given image in the file path.
        /// </summary>
        /// <param name="filePath">File path of the image.</param>
        public override void  getFileInformation(string filePath)
        {
            FileInfo fileInformation = new FileInfo(filePath);
            if (fileInformation.Exists)
            {
                Name = fileInformation.Name;
                FileType = fileInformation.Extension;
                Size = fileInformation.Length;
                CreationDate = fileInformation.CreationTime;
                ModificationDate = fileInformation.LastWriteTime;
                Height = calculatePictureHeight(filePath);
                Width = calculatePictureWidth(filePath);                
            }
        }

        public override void getThumbnail(string filePath)
        {            
            Image image = Image.FromFile(filePath);
            Thumbnail = image.GetThumbnailImage(40,40,null,new IntPtr());            
        }

        private int calculatePictureHeight(string filePath)
        {
            var image = Image.FromFile(filePath);
            return image.Height;
        }

        private int calculatePictureWidth(string filePath)
        {
            var image = Image.FromFile(filePath);
            return image.Width;
        }
    }
}

在这里,我正在使用该类从给定文件夹中的每个文件中提取信息：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.IO;

namespace SharpLibrary_MediaManager
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        string folderPath = @"D:ImagesPictureFolder";

        private void button1_Click(object sender,EventArgs e)
        {
            DirectoryInfo folder = new DirectoryInfo(folderPath);
            List<Picture> lol = new List<Picture>();
            foreach (FileInfo x in folder.GetFiles())
            {
                Picture picture = new Picture();
                picture.getFileInformation(x.FullName);
                lol.Add(picture);
            }

            MessageBox.Show(lol[0].Name);
        }
    }
}

我得到了Out Of Memory异常,我真的不知道为什么.这是我第一次做这样的事情所以我对批处理文件处理等很陌生.

有帮助吗？
