rdlc报告未显示报告

Question

我正在显示rdlc报告，但它给出了错误(未指定"RptAttendence.rdlc“报告的报告定义)。这是我的代码，我用它做了什么？提前谢谢。

private void RptAttendence_Load(object sender, EventArgs e)
        {
            try
            {
                OleDbConnection con = new OleDbConnection(@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Users\jani\Documents\saloo.accdb");
                OleDbCommand cmd = new OleDbCommand();
                cmd.CommandText = "SELECT Student.Name, Student.FName,Class.Name As Class, [Section].Name As [Section], Attendence.Attendence, Attendence.Dat As [Date] From " +
                    "(((Attendence Inner join Student on Attendence.StudentID =Student.ID) inner join Class on Attendence.ClassID= Class.ID) inner join [Section] ON Attendence.SectionID = [Section].ID)";
                OleDbDataAdapter adapter = new OleDbDataAdapter();
                DataTable table = new DataTable();
                cmd.Connection = con;
                con.Open();
                adapter.SelectCommand = cmd;
                adapter.Fill(table);

                reportViewer1.LocalReport.ReportEmbeddedResource = "Attendence.RptAttendence.rdlc";

                ReportDataSource source = new ReportDataSource("Dataset1", table);
                reportViewer1.LocalReport.DataSources.Clear();
                reportViewer1.LocalReport.DataSources.Add(source);
                reportViewer1.LocalReport.Refresh();
                this.reportViewer1.RefreshReport();
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }

假设您使用的是Visual Studio -我认为您的问题可以通过在解决方案资源管理器中右键单击您的报告并进入属性来解决。

在属性中，将生成操作更改为Embedded Resource，然后再次运行项目
