从嵌入式资源加载 Crystal Report [英] Loading Crystal Report from embedded resource

问题描述

我有一个 ASP.NET 网站和一个引用的类库项目.在这个类库中，我有一个 Crystal Report 设置为嵌入式资源.我想将报表动态加载到 CrystalReportViewer 中.

I have an ASP.NET website and a referenced class library project. In this class library I have a Crystal Report set as embedded resource. I want to load the report dynamically into a CrystalReportViewer.

我该怎么做?

推荐答案

我想出了如何解决这个问题.将 Crystal Report 添加到类库项目时，它会创建一个相应的类，该类继承自 ReportClass.该类的一个实例可以用作查看器的 ReportSource.

I figured out how to solve that problem. When a Crystal Report is added to a Class Library project, it creates a corresponding class, which inherits from ReportClass. An instance of this class can be used as ReportSource of the viewer.

例子:

var report = new CrystalReport1();
report.SetDataSource(datasource);
CrystalReportViewer1.ReportSource = report;
