推荐答案

以下示例代码显示了我通常如何配置报告.您缺少的行是 DataSources.Add:

Here is sample code showing how I usually configure a report. The line you are missing is the DataSources.Add:

  ReportViewer1.LocalReport.ReportPath = "<your rdlc>"
  ReportViewer1.LocalReport.DataSources.Add(New ReportDataSource("DataSet1", <your data>))
  ReportViewer1.LocalReport.SetParameters(New ReportParameter("deptName", "Finance"))
  ReportViewer1.RefreshReport()

"DataSet1" 对应于 rdlc 文件中的名称.

"DataSet1" corresponds to a name inside your rdlc file.

对应于您提供的数据.它可以是 DataTable、IEnumerable、BindingSource 等.

<your data> corresponds to data that you provide. It can be a DataTable, IEnumerable, BindingSource, etc.
