            }

        }

    }

}

其中会用到的文件名、文件路径非法字符替换方法：

        /// <summary>  

        /// Remove invalid characters which are not allowed in the file name  

        /// </summary>  

        /// <param name="fileName"></param>  

        /// <returns></returns>  

        public string RemoveFileNameInvalidChar(string fileName)

        {

            if (string.IsNullOrEmpty(fileName))



                return fileName;



            string invalidChars = new string(Path.GetInvalidFileNameChars());



            string invalidReStr = string.Format("[{0}]", Regex.Escape(invalidChars));



            return Regex.Replace(fileName, invalidReStr, "");



        }



        /// <summary>  

        /// Remove invalid characters which are not allowed in the path names  

        /// </summary>  

        /// <param name="filePath"></param>  

        /// <returns></returns>  

        public string RemovePathInvalidChar(string filePath)

        {



            if (string.IsNullOrEmpty(filePath))



                return filePath;



            string invalidChars = new string(Path.GetInvalidPathChars());



            string invalidReStr = string.Format("[{0}]", Regex.Escape(invalidChars));



            return Regex.Replace(filePath, invalidReStr, "");



        }
