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:\Images\PictureFolder";

        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？ 原文链接：https://www.f2er.com/csharp/98636.html
