        OpenFileDialog lvse = new OpenFileDialog();
            lvse.Title = "选择图片";
            lvse.InitialDirectory = "";
            lvse.Filter = "图片文件|*.bmp;*.jpg;*.jpeg;*.gif;*.png";
            lvse.FilterIndex = 1;

            if (lvse.ShowDialog() == DialogResult.OK)
            {
                string Path = lvse.FileName.ToString();//获取文件目录
                string Name = Path.Substring(Path.LastIndexOf("\\") + 1);//获取文件名
                ...
