问题描述

点击下一步按钮，图片更改，但文件名永不改变;



我尝试过：

Click Next button, picture change but Filename never change;

What I have tried:

private void button2_Click(object sender, System.EventArgs e)
        {
            if (folderBrowserDialog1.ShowDialog() == DialogResult.OK)
            {
                listBox1.Items.Clear();
                listBox1.Refresh();
                listBox1.Sorted = true;
                string[] part1 = null, part2 = null, part3 = null;
                part1 = Directory.GetFiles(folderBrowserDialog1.SelectedPath, "*.jpg");
                part2 = Directory.GetFiles(folderBrowserDialog1.SelectedPath, "*.jpeg");
                part3 = Directory.GetFiles(folderBrowserDialog1.SelectedPath, "*.bmp");

                folderFile = new string[part1.Length + part2.Length + part3.Length];

                Array.Copy(part1, 0, folderFile, 0, part1.Length);
                Array.Copy(part2, 0, folderFile, part1.Length, part2.Length);
                Array.Copy(part3, 0, folderFile, part1.Length + part2.Length, part3.Length);

                selected = 0;
                //begin = 0;
                end = folderFile.Length;

                showImage(folderFile[selected]);

                string folderName = this.folderBrowserDialog1.SelectedPath;
                foreach (string f in Directory.GetFiles(folderName))
                {
                    if (f.ToLower().EndsWith(".jpg")==true || f.ToLower().EndsWith(".jpeg")==true)
                    {
                        this.listBox1.Items.Add(Path.GetFileNameWithoutExtension(f));
                    }
                button1.Enabled = true;
                button3.Enabled = true;
                listBox1.Enabled = true;
            }
                //label1.Text = this.folderBrowserDialog1.SelectedPath;
            }             
  }
private void nextImage()
{
if(selected == folderFile.Length - 1)
{
selected = 0;	
showImage(folderFile[selected]);

}
else
{
selected = selected + 1; 
showImage(folderFile[selected]);
}
}

推荐答案

使用System;

使用System.Collections。 Generic;

使用System.ComponentModel;

使用System.Data;

使用System.Drawing;

使用System.Linq;

使用System.Text;

使用System.Threading.Tasks;

使用System.Windows.Forms;

使用System.IO;



命名空间folderBrowser

{

公共部分类Form1：表格

{

public Form1（）

{

InitializeComponent（）;

}



private void button1_Click（object sender，EventArgs e）

{

string [] filters = {* .jpg，* .jpeg，* .png，* .gif，* .bmp};

//改变你的路径

var directory = new DirectoryInfo（@C：\ Pictures）;



var files = new List< fileinfo>（）;



foreach（过滤器中的var过滤器）

{

var results = directory.GetFiles（filter，SearchOption.AllDirectories）;

files.AddRange（results）;

}



foreach（文件中的var文件）

{

listBox1.Items.Add（（file））;

} < br $>


}



private void listBox1_MouseClick（object sender，MouseEventArgs e）

{

pictureBox1.Image = Image.FromFile（（（FileInfo）listBox1.SelectedItem）.FullName）;

}



private void listBox1_SelectedIndexChanged（object sender，EventArgs e）

{

pictureBox1.Image = Image.FromFile（（（FileInfo）listBox1.SelectedItem）.FullName） ;

}

var directory = new DirectoryInfo(@"C:\Pictures");

var files = new List<fileinfo>();

foreach (var filter in filters)
{
var results = directory.GetFiles(filter, SearchOption.AllDirectories);
files.AddRange(results);

foreach (var file in files)
