对临时文件的一些存放与清理等问题

1.创建相应的文件夹

        /// <summary>
        /// 按名字创建相应的文件夹
        /// </summary>
        /// <param name="dirName"></param>
        /// <returns></returns>
        private string CreatePdfPath(string dirName)
        {
            string dirpath = System.AppDomain.CurrentDomain.SetupInformation.ApplicationBase + @"..\..\..\TemporaryFiles\";
            dirpath = @dirpath + @dirName + @"\";
            if (!Directory.Exists(dirpath))
                Directory.CreateDirectory(dirpath);
            return @dirpath;
        }

2.删除临时文件

        /// <summary>
        /// 删除临时文件
        /// </summary>
        /// <param name="filePath"></param>
        private void DelSourceFiles(string filePath)
        {
            System.IO.File.Delete(filePath);
        }
