c# equivalent of java

Question

What is the equivalent in c # of the following java code?

import java.security.MessageDigest;
import javax.xml.bind.DatatypeConverter;
public String algoritmoHash(byte[] pArchivo, String algorithm) {
   String hashValue = "";
   try {
         MessageDigest messageDigest = MessageDigest.getInstance(algorithm);
         messageDigest.update(pArchivo);
         byte[] digestedBytes = messageDigest.digest();
         hashValue = DatatypeConverter.printHexBinary(digestedBytes).toLowerCase();
   }
   catch (Exception e) {
      System.out.println("Error generando Hash");
   }
   return hashValue;
}

And what is the equivalent of this other java code?

import java.util.zip.Checksum;
import java.util.zip.CRC32;
public String calCrc32(byte[] data) {
   Checksum checksum = new CRC32();
   checksum.update(data, 0, data.length);
   long checksumValue = checksum.getValue();
   String hex = Long.toHexString(checksumValue).toUpperCase();
   while (hex.length() < 8) {
      hex = "0" + hex;
   }
   return hex;
}
