如何在C＃中获取文件的crc32和文件的比例.... [英] How can get crc32 of files in C# and proporties of file....

问题描述

如何以c＃和文件比例获取文件的crc32 ....



我尝试过：



我在google上找了好几件东西但我找不到任何东西........

解决方案

< blockquote>这有三个部分：

1）读取文件内容。

2）计算你读取的字节的CRC32。

3）获取文件属性。



第一个是微不足道的：

  byte  [] data = File.ReadAllBytes（pathToFile）; 

第二个更复杂，但这应该会有所帮助：如何计算C＃中的CRC [ ^ ]



最后一部分又是微不足道的，只需使用 FileInfo类（System.IO） [ ^ ]：

 FileInfo fi =  new  FileInfo（pathToFile）; 

你应该回到C / C ++基础知识

我必须读取哪种格式的文件？

这个cote让我们想一想你跳过了一些基本原理。这个问题毫无意义。



我知道链接不是C＃，而C＃来自C来自C ++。

What I have tried:

I have looked for several things on the google but i cannot find anything........

解决方案

There are three parts to this:
1) Read the file content.
2) Calculate the CRC32 of the bytes you read.
3) Get file properties.

The first is trivial:

byte[] data = File.ReadAllBytes(pathToFile);

The second is more complex, but this should help: How to calculate a CRC in C#[^]

The final part is trivial again, just use the FileInfo Class (System.IO)[^]:

FileInfo fi = new FileInfo(pathToFile);

You should come back to C/C++ basics

I have to read the file which format?

This cote let us think that you skipped some of the fundamentals. The question makes no sense.

I know the links are not C#, but C# comes from ++ which comes from C.
