1)byte[] bt=ms.ToArray(); (2)MemoryStream ms=new MemoryStream();ms.Write(bt,0,ms.Length); 7、byte[]与base64string...的互相转换 在C#中 图片到byte[]再到base64string的转换： Bitmap bmp = new Bitmap(filepath);...ms.Length); ms.Close(); string pic = Convert.ToBase64String(arr); base64string...Image image = Image.FromStream(memoryStream); 现在的数据库开发中：图片的存放方式一般有CLOB:存放base64string...因为图片可以直接转换为byte[]存放到数据库中 若使用base64string 还需要从byte[]转换成base64string 。更浪费性能。

在将图片流 utf8 解码时踩了坑，一开始 buffer 解码时采用如下方法： let base64String = String.fromCharCode(...new Uint8Array(buffer...let base64String = new TextDecoder('utf-8').decode(buffer) TextEncoder and TextDecoder from the Encoding...process(buffer) { // 将 buffer 转换为base64 let view = new TextDecoder('utf-8').decode(buffer) let base64String...= view.toString(CryptoJS.enc.Base64) // 解密 let decryptedData = CryptoJS.AES.decrypt(base64String
方案思路：在userdata里加start-sleep 120的设计，比如这个userdata代码，即便公共镜像买出来的机器，购买后过5分钟去看，打印服务是Auto 、Running的 #ps1 $base64String...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" $decodedContent = [System.Convert]::FromBase64String($base64String
