复制文件及文件夹

static readonly private string path = AppDomain.CurrentDomain.BaseDirectory;

string file_name = "文件名.文件类型";
string s_path = path + file_name;
string d_path = folderBrowserDialog1.SelectedPath + "//" + file_name;
if (File.Exists(s_path))
{
          File.Copy(s_path, d_path, true);

          if (File.Exists(d_path))
               lb_error_info.Text = "复制文件" + file_name + "至" + folderBrowserDialog1.SelectedPath + "成功！/n";
}
else
{
          lb_error_info.Text = "源文件不存在！";
          return;
}

当然，WindowsForm里有FolderBrowserDialog和Label控件，分别名为folderBrowserDialog1和lb_error_info

 

//拷贝bin/Debug下文件到目标文件夹
string source_path_Permanence = path + "Permanence//";
string dest_path_Permanence = folderBrowserDialog1.SelectedPath + "//Permanence//";
CopyFolder(source_path_Permanence, dest_path_Permanence);

 

private void CopyFolder(string source_path, string dest_path)
{
        //检查文件夹
        if (!Directory.Exists(dest_path))
             Directory.CreateDirectory(dest_path);
        //子文件夹
        foreach (string sub_path in Directory.GetDirectories(source_path))
             CopyFolder(sub_path + "//", dest_path + Path.GetFileName(sub_path) + "//");
        //文件
        foreach (string file in Directory.GetFiles(source_path))
                File.Copy(file, dest_path + Path.GetFileName(file), true);
}
