c# 目录文件夹加前缀名
1 知识要点
1.1 修改文件名称
string srcFileName = @"D:/a.txt";
string destFileName = @"D:/b.txt";
if (System.IO.File.Exists(srcFileName))
{
System.IO.File.Move(srcFileName, destFileName);
}1.2 修改文件夹名称
string srcFolderPath = @"D:/1";
string destFolderPath = @"D:/6";
if (System.IO.Directory.Exists(srcFolderPath))
{
System.IO.Directory.Move(srcFolderPath, destFolderPath);
}2 今天应用目录文件夹加前缀名采用b修改文件夹名称
2.1 设计界面如下
2.2引用带地址行类插件代码（FolderBrowser.cs）如下
using System;
using System.ComponentModel;
using System.Drawing.Design;
using System.Runtime.InteropServices;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace test
{
public class FolderNameEditor : UITypeEditor
{
public override UITypeEditorEditStyle GetEditStyle(ITypeDescriptorContext context)
{
return UITypeEditorEditStyle.Modal;
}
public override object EditValue(ITypeDescriptorContext context, IServiceProvider provider, object value)
{
FolderBrowserDialog browser = new FolderBrowserDialog();
if (value != null)
{
browser.DirectoryPath = string.Format("{0}", value);
}
if (browser.ShowDialog(null) == DialogResult.OK)
return browser.DirectoryPath;
return value;
}
}
#region FolderBrowserDialog Base
///
/// Vista 样式的选择文件对话框的基类
///
[Description("提供一个Vista样式的选择文件对话框")]
[Editor(typeof(FolderNameEditor), typeof(UITypeEditor))]
public class FolderBrowserDialog : Component
{
///
/// 初始化 FolderBrowser 的新实例
///
public FolderBrowserDialog()
{
}
#region Public Property
///
/// 获取在 FolderBrowser 中选择的文件夹路径
///
public string DirectoryPath { get; set; }
///
/// 向用户显示 FolderBrowser 的对话框
///
/// 任何实现 System.Windows.Forms.IWin32Window（表示将拥有模式对话框的顶级窗口）的对象。
/// 2.3 按钮事件
2.3.1选择文件夹所在目录
public static string tpml;//定义全局变量
public static string tpml2;
private void button1_Click(object sender, EventArgs e)
{
FolderBrowserDialog path = new FolderBrowserDialog();
if (path.ShowDialog(this) == DialogResult.OK)
{
tpml = path.DirectoryPath;
tpml2 = textBox1.Text;
Director(tpml);
}
}效果如下
2.3.2 历遍所有目录
void Director(string dir)
{
DirectoryInfo d = new DirectoryInfo(dir);
FileSystemInfo[] fsinfos = d.GetFileSystemInfos();
List lsTest2 = new List(); //存储符合要求的文件的FiledInfo
foreach (FileSystemInfo fsinfo in fsinfos)
{
if (fsinfo is DirectoryInfo) //判断是否为文件夹
{
string destFolderPath = fsinfo.FullName.Replace(fsinfo.Name, "")+textBox1.Text+ fsinfo.Name;
if (System.IO.Directory.Exists(fsinfo.FullName))
{
System.IO.Directory.Move(fsinfo.FullName, destFolderPath);
}
Director(fsinfo.FullName);//递归调用
}
}
}
