Build wheels: C # converts pictures into base64 strings

1. Convert the picture into a Base64 string in C #:

usingSystem;usingSystem.Collections.Generic;usingSystem.Linq;usingSystem.Text;usingSystem.IO;namespaceconvertimgtobase64{classProgram {Static voidMain (string[] args) {FileInfo file=NewFileInfo ("1.png"); varstream =file.         OpenRead (); byte[] buffer =New byte[File.         Length]; //read picture byte streamStream. Read (Buffer,0, Convert.ToInt32 (file.         Length)); //Save the Base64 string to the Base64.txt fileStreamWriter SW =NewStreamWriter ("Base64.txt",false, Encoding.UTF8); //Convert a byte stream into a base64 stringSW.         Write (convert.tobase64string (buffer)); Sw.         Close (); Console.WriteLine ("Convert successful!");      Console.read (); }   }}

The 64-bit encoding exists in the TXT file,

2. Embed the base64 encoded image in the CSS

. main {    width:600px;    height:300px;    Background-image:url (data:image/gif;base64, R0LGODLHCAAIAJEAAONP6ETK5O7M8AAAACH5BAEAAAIALAAAAAAIAAGAAAINJAMJH2Q6DNXOVSQMLQA7);}

When the page style is applied to main, the display effect is a GIF background:

3. Place the base64 encoded image directly into the IMG tag

<img src="data:image/jpeg;base64, R0lgodlhcaaiajeaaonp6etk5o7m8aaaach5baeaaaialaaaaaaiaagaaainjamjh2q6dnxovsqmlqa7alt= " BASE64 encoded Image "

This also allows you to load a stream of bytes into a JPG image of the page
