Answer 1

openFile文件选择控件设置允许多选,然后处理返回的文件对象数组,循环调用DeleteFile方法

Answer 2

    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        private void Form1_Load(object sender, EventArgs e)
        {
            this.openFile.Multiselect = true;
        }
        private void DeleteFile(string[] str)
        {
            //string Path = paramPath.Substring(paramPath.LastIndexOf("\\") + 1);
            foreach (string FliePath in openFile.FileNames)
            {
                if (System.IO.File.Exists(FliePath))
                {
                    if (MessageBox.Show("Whether delete? \n" + FliePath, "Hint", MessageBoxButtons.YesNo, MessageBoxIcon.Warning) != DialogResult.Yes)
                    {
                       continue;
                    }
                    else
                    {
                        File.Delete(FliePath);
                        
                    }
                }
                //else
                //{
                //    MessageBox.Show("The document done not want to delete !");
                //}
            }
            MessageBox.Show("The document deletes success!");
        }        private void btnDelete_Click(object sender, EventArgs e)
        {
            if (this.openFile.ShowDialog() == DialogResult.OK)
            {
                string[] FliePath = this.openFile.FileNames;
                this.DeleteFile(FliePath);
            }
        }
