本例实现了批量更改文件或图片的名称。具体设计思路如下所示
- 获取文件夹路径
- 获取文件夹中所有文件的文件名
- 删除文件名并对文件名进行批量修改
窗口设计如下图所示：
程序代码如下：

string[] files;//选择文件的集合，此处声明数组是因为openFileDialog1.FileNames返回值为string[]
FileInfo fi;//创建一个FileInfo对象，用于获取文件信息
string[] lvFiles=new string[7];//向控件中添加的行信息
Thread td;//处理批量更名方法的线程

{
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
listView1.GridLines = true;//是否显示网格线
listView1.Items.Clear();//使用了listview.item.clear()后，listview控件中仍然保存着listviewitem项的结构，即listview有多个列，每列可能对应的列标题数据等。
//而当你使用了listview.clear()后，整个listview内保存数据的结构就没了。
files = openFileDialog1.FileNames;//openFileDialog1.FileNames打开的可能是多个文件，因此返回值为string[]
for (int i = 0; i < files.Length; i++)//files.Length为打开的文件个数
{
string path = files[i].ToString();
fi = new FileInfo(path);
string name = path.Substring(path.LastIndexOf("\\") + 1, path.Length - 1 - path.LastIndexOf("\\"));//listview文件名
string ftype = path.Substring(path.LastIndexOf("."), path.Length - path.LastIndexOf(".")); //listview扩展名
string createTime = fi.CreationTime.ToShortDateString();//listview日期
double a = Convert.ToDouble(Convert.ToDouble(fi.Length) / Convert.ToDouble(1024));
string fsize = a.ToString("0.0") + " KB";//listview 大小
lvFiles[0] = name;
lvFiles[1] = name;
lvFiles[2] = ftype;
lvFiles[3] = createTime;
lvFiles[4] = path.Remove(path.LastIndexOf("\\") + 1);
lvFiles[5] = fsize;
ListViewItem lvi = new ListViewItem(lvFiles);
lvi.UseItemStyleForSubItems = false;
lvi.SubItems[1].BackColor = Color.AliceBlue;
listView1.Items.Add(lvi);
}
tsslSum.Text = listView1.Items.Count.ToString();
}
}

}
}
}
运行效果如下：
