C # BASE64 encoding and picture conversion code

The process of converting a picture to a Base64 string is to first serialize the picture file into binary data using BinaryFormatter, and then use the ToBase64String method of the Convert class. The process of converting a Base64 string to a picture is reversed: Use the frombase64string of the convert class to get the binary data of the picture file, and then use the BinaryFormatter deserialization method.
