如何在 VS Visual Studio 2010 Basic 的报表查看器中加载带有参数的 .rdlc 报表？

Question

我不知道是什么问题，我的笔记中有相同的代码。报表查看器不会加载带有参数的 .rdlc 报表。我有相同的对象名称和参数名称。我在报告查看器的小箭头链接中选择了 .rdlc 报告。所以请放心，它应该将 .rdlc 与报告查看器连接起来，我有以下代码。

导入 Microsoft.Reporting.WinForms

尝试使用报告参数列表，而不是您的方法。

创建列表，将每个报表参数对象添加到其中，然后将列表传递给

ReportViewer1.LocalReport.SetParameters()

希望有帮助！
