C#生成ZIP压缩包

生成ZIP压缩包C#代码如下：

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, "");        }
