如何使用c＃将system.weing.image转换为system.web.ui.webcontrols.image [英] how to convert convert system.drawing.image to system.web.ui.webcontrols.image using c#

问题描述

byte [] rawImg =（byte []）ds.Tables [0] .Rows [0] [emp_image];

MemoryStream Stream = new MemoryStream（）;

Stream.Write（rawImg，0，rawImg.Length）;

Bitmap Display_Picture = new Bitmap（Stream）;



image1 =（Display_Picture）;

byte[] rawImg = (byte[])ds.Tables[0].Rows[0]["emp_image"];
MemoryStream Stream = new MemoryStream();
Stream.Write(rawImg, 0, rawImg.Length);
Bitmap Display_Picture = new Bitmap(Stream);

image1 = (Display_Picture);

推荐答案

它们是两个完全不同的东西。 System.Web.UI.WebControls.Image 是一个控件，具体来说它会导致 img 标记。 System.Drawing.Image 表示位图，图像本身。



可以找到一个潜在的解决方案此处 [ ^ ]（完全向下滚动）

They are two completely different things. System.Web.UI.WebControls.Image is a control, to specific it'll result in an img tag on an ASP.NET page. System.Drawing.Image represents a bitmap, the image itself.
