将生成的图像加载到 asp 图像控件中而不进行物理保存

Question

我正在尝试将图像加载到 asp 图像控件中。该图像是从 zxing Barcode Writer 生成的。我的问题是，我可以加载它而不先进行物理保存吗？

string barcode = "xxxxxx";
BarcodeWriter writer = new BarcodeWriter() { Format = BarcodeFormat.CODE_128 };

imgBarCode.ImageUrl = writer.Write(barcode);

...如何将writer.Writer引用到图像控制"imgBarCode"

Answer 1

根据 user1429080 的建议，我得到了这个：

string barcode = "12345"

BarcodeWriter writer = new BarcodeWriter() { Format = BarcodeFormat.CODE_128, Options = new ZXing.Common.EncodingOptions { Height = 100, Width = 300 } };

var bitmap = writer.Write(barcode);    
MemoryStream ms = new MemoryStream();
bitmap.Save(ms, ImageFormat.Jpeg);
var b64 = Convert.ToBase64String(ms.ToArray());

imgBarCode.ImageUrl = "data:image/jpeg;base64," + b64;
