【C#实现的4种常用数据校验方法小结(CRC校验|C#实现的4种常用数据校验方法小结(CRC校验,LRC校验,BCC校验,累加和校验)】CRC即循环冗余校验码（Cyclic Redundancy Check）：是数据通信领域中最常用的一种查错校验码，其特征是信息字段和校验字段的长度可以任意选定。循环冗余检查（CRC）是一种数据传输检错功能，对数据进行多项式计算，并将得到的结果附在帧的后面，接收设备也执行类似的算法，以保证数据传输的正确性和完整性。
CRC算法参数模型解释：

• NAME：参数模型名称。
• WIDTH：宽度，即CRC比特数。
• POLY：生成项的简写，以16进制表示。例如：CRC-32即是0x04C11DB7，忽略了最高位的"1"，即完整的生成项是0x104C11DB7。
• INIT：这是算法开始时寄存器（crc）的初始化预置值，十六进制表示。
• REFIN：待测数据的每个字节是否按位反转，True或False。
• REFOUT：在计算后之后，异或输出之前，整个数据是否按位反转，True或False。
• XOROUT：计算结果与此参数异或后得到最终的CRC值。

i++){crc ^= (uint)(buffer[i] << 24); for (int j = 0; j < 8; j++){if ((crc & 0x80000000) > 0)crc = (crc << 1) ^ 0x04C11DB7; elsecrc = crc << 1; }}byte[] ret = BitConverter.GetBytes(crc); Array.Reverse(ret); return ret; }

检验和(checksum)，在数据处理和数据通信领域中，用于校验目的地一组数据项的和。它通常是以十六进制为数制表示的形式。如果校验和的数值超过十六进制的FF,也就是255. 就要求其补码作为校验和。通常用来在通信中，尤其是远距离通信中保证数据的完整性和准确性。

public static byte[] allAdd(byte[] buffer, int start = 0, int len = 0){if (buffer == null || buffer.Length == 0) return null; if (start < 0) return null; if (len == 0) len = buffer.Length - start; int length = start + len; if (length > buffer.Length) return null; byte bcc = 0; // Initial valuefor (int i = start; i < len; i++){bcc ^= buffer[i]; }return new byte[] { bcc }; }

到此这篇关于C#实现的4种常用数据校验方法小结(CRC校验,LRC校验,BCC校验,累加和校验)的文章就介绍到这了,更多相关C# 数据校验内容请搜索脚本之家以前的文章或继续浏览下面的相关文章希望大家以后多多支持脚本之家！
