C#获取文件名

        public string open_new_document()
        {
            string document_name = "读取失败";
            OpenFileDialog open_new_document = new OpenFileDialog();
            open_new_document.InitialDirectory = "C:/Users/Administrator/Desktop";
            //默认读取路径
            open_new_document.Multiselect = true;
            //该值确定是否可以选择多个文件
            open_new_document.Title = "请选择文件";
            open_new_document.Filter = "mdb格式（*.mdb）|*.mdb|所有文件|*.*";
            if (open_new_document.ShowDialog() == System.Windows.Forms.DialogResult.OK)
            {
                DialogResult dr = MessageBox.Show(open_new_document.FileName, "是否读取该文件", MessageBoxButtons.OKCancel, MessageBoxIcon.Question);
                if (dr == DialogResult.OK)
                {
                    document_name = open_new_document.FileName;
                }
            }

            return document_name;
        }

调用的时候判断一下返回值是否为"读取失败"即可。
