Method for calculating file MD5 verification in C#

This article describes the method of MD5 verification of C# calculation file. Share it for your reference. The specific analysis is as follows:

C# calculates the MD5 verification of the file. Download a file from the Internet. You can use the following code to perform MD5 verification on the file to see if the generated MD5 encoding is consistent with the website. If it is inconsistent, it means that the file has been modified. Be careful.

protected string GetMD5HashFromFile(string fileName)
{
 FileStream file = new FileStream(fileName,);
 MD5 md5 = new MD5CryptoServiceProvider();
 byte[] retVal = (file);
 ();
 ASCIIEncoding enc = new ASCIIEncoding();
 return (retVal);
}

I hope this article will be helpful to everyone's C# programming.
