嘿,我几天前就开始学习C#了,我正在尝试制作一个程序,它可以复制和粘贴文件(如果需要的话)到一个选定的目录中,但是我不知道如何从openfiledialog和folderBrowser对话框中获得目录和文件路径。

我做错什么了?

下面是代码:

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

        private void direc_Click(object sender, EventArgs e)
        {
            string folderPath = "";
            FolderBrowserDialog directchoosedlg = new FolderBrowserDialog();
            if (directchoosedlg.ShowDialog() == DialogResult.OK)
            {
                folderPath = directchoosedlg.SelectedPath;
            }
        }

        private void choof_Click(object sender, EventArgs e)
        {

            OpenFileDialog choofdlog = new OpenFileDialog();
            choofdlog.Filter = "All Files (*.*)|*.*";
            choofdlog.FilterIndex = 1;

            choofdlog.Multiselect = true;
            choofdlog.ShowDialog();
        }

        private void replacebtn_Click(object sender, EventArgs e)
        {
          // This is where i'm having trouble
        }

        public static void ReplaceFile(string FileToMoveAndDelete, string FileToReplace, string BackupOfFileToReplace)
        {
            File.Replace(FileToMoveAndDelete, FileToReplace, BackupOfFileToReplace, false);
        }
    }

为OpenFileDialog

OpenFileDialog choofdlog = new OpenFileDialog();
choofdlog.Filter = "All Files (*.*)|*.*";
choofdlog.FilterIndex = 1;
choofdlog.Multiselect = true;

if (choofdlog.ShowDialog() == DialogResult.OK)    
{     
    string sFileName = choofdlog.FileName; 
    string[] arrAllFiles = choofdlog.FileNames; //used when Multiselect = true           
}

为FolderBrowserDialog

FolderBrowserDialog fbd = new FolderBrowserDialog();
fbd.Description = "Custom Description"; 

if (fbd.ShowDialog() == DialogResult.OK)
{
    string sSelectedPath = fbd.SelectedPath;
}

进入selected folderselected file name可以将两个字符串声明为类级

namespace filereplacer
{
   public partial class Form1 : Form
   {
      string sSelectedFile;
      string sSelectedFolder;

      public Form1()
      {
         InitializeComponent();
      }

      private void direc_Click(object sender, EventArgs e)
      {
         FolderBrowserDialog fbd = new FolderBrowserDialog();
         //fbd.Description = "Custom Description"; //not mandatory

         if (fbd.ShowDialog() == DialogResult.OK)      
               sSelectedFolder = fbd.SelectedPath;
         else
               sSelectedFolder = string.Empty;    
      }

      private void choof_Click(object sender, EventArgs e)
      {
         OpenFileDialog choofdlog = new OpenFileDialog();
         choofdlog.Filter = "All Files (*.*)|*.*";
         choofdlog.FilterIndex = 1;
         choofdlog.Multiselect = true;

         if (choofdlog.ShowDialog() == DialogResult.OK)                 
             sSelectedFile = choofdlog.FileName;            
         else
             sSelectedFile = string.Empty;       
      }

      private void replacebtn_Click(object sender, EventArgs e)
      {
          if(sSelectedFolder != string.Empty && sSelectedFile != string.Empty)
          {
               //use selected folder path and file path
          }
      }
      ....
}

可以将路径存储到字符串变量中,如下所示

string s = choofdlog.FileName;
