如何显示在一个RDLC报表图像 [英] How to show images on an RDLC report

问题描述

我有一个RDLC报告，并希望在表中的一列本报告中显示的图像上。数据源为我的报告是，有一个叫做类System.Drawing.Image对象的图像属性的一类。

I have an RDLC report and would like one of the columns in a table on this report to display images. The datasource for my report is a class that has a property called Image of type System.Drawing.Image.

在我的报告中，我将图像控件拖到列，我设置以下属性：

On my report I dragged an image control onto the column and I set the following properties:

MIMEType:  image/png
Source:  Database
Value:  =Fields!Image.Value

当我跑我的报告，我得到一个破碎的形象。

When I run my report, I get a broken image.

我真的AP preciate任何建议！

I'd really appreciate any suggestions!

在此先感谢：O）

推荐答案

我不知道这是不是最好的解决办法，但我得到它的工作。它看起来像问题是使用System.Drawing.Image对象。

I don't know if this is the best solution, but I got it to work. It looks like the problem was in using System.Drawing.Image.

在我的课，我创建了一个名为[]类型字节ImageByte新的属性。我没有做一个二传手的ImageByte，但我做了一个getter，做了以下内容：

In my class, I created a new property called ImageByte of type byte[]. I didn't make a setter for ImageByte, but I made a getter that does the following:

MemoryStream ms = new MemoryStream();
Image.Save(ms, System.Drawing.Imaging.ImageFormat.Png);
return ms.ToArray();

！

我更新了我的报告有=字段ImageByte.Value的价值，现在一切似乎是按预期工作：O）

I updated my report to have =Fields!ImageByte.Value for the Value and now everything appears to be working as expected :o)
