Sample code sharing of how C# uses ReportViewer to generate reports (picture)
This article mainly introduces the code related to generating reports using ReportViewer in detail. It has certain reference value. Interested friends can refer to it.The main content of this article is This is a small example of report design using Microsoft's own
controlReportViewer. The specific content is as follows
Involved knowledge points:ReportViewer: Located in Microsoft .Reporting.WinForms namespace, mainly used for report display
Report: report, file ending with rdlc, visual design report template.Report data: built-in fields, parameters, images,
Datasets
(This report mainly uses parameters, and data sets) ReportParameter: Use names and values to instantiate new report parameters ReportDataSource: The data source of the report is linked to the Data
Table object
is as follows:
The relevant codes are as follows:
/// <summary>
/// 设置报表
/// </summary>
private void SetReport()
{
//第一步：清除之前的数据
this.rptView.LocalReport.DataSources.Clear();
//第二步：指定报表路径
this.rptView.LocalReport.ReportPath = "Report2.rdlc";
//第三步：构造新的DataTable
DataTable dt = new DataTable("DataTable1");
dt.Columns.Add("Name");
dt.Columns.Add("Score");
dt.Columns.Add("Id");
dt.Rows.Add(new object[] { "语文", 80, "Y0001" });
dt.Rows.Add(new object[] { "数学", 75, "S0001" });
dt.Rows.Add(new object[] { "英文", 96, "E0001" });
//名称不能写错，和报表中的数据集名称一致
ReportDataSource rdsItem = new ReportDataSource("DataSet1", dt);
//此处可以有多个数据源
this.rptView.LocalReport.DataSources.Add(rdsItem);
//第四步：构造参数
List<ReportParameter> lstParameter = new List<ReportParameter>() {
new ReportParameter("Title",this.txtTitle.Text),
new ReportParameter("Id",this.txtId.Text),
new ReportParameter("Name",this.txtName.Text),
new ReportParameter("Age",this.txtAge.Text),
new ReportParameter("Sex",this.txtSex.Text),
new ReportParameter("Salary",this.txtSalary.Text),
new ReportParameter("Depart",this.txtDepart.Text)
};
this.rptView.LocalReport.SetParameters(lstParameter);
this.rptView.ZoomMode = ZoomMode.Percent;
this.rptView.ZoomPercent = 100;
//第五步：刷新报表
this.rptView.RefreshReport();

The difference between multithreading and asynchronous c#
Apr 03, 2025 pm 02:57 PM
The difference between multithreading and asynchronous is that multithreading executes multiple threads at the same time, while asynchronously performs operations without blocking the current thread. Multithreading is used for compute-intensive tasks, while asynchronously is used for user interaction. The advantage of multi-threading is to improve computing performance, while the advantage of asynchronous is to not block UI threads. Choosing multithreading or asynchronous depends on the nature of the task: Computation-intensive tasks use multithreading, tasks that interact with external resources and need to keep UI responsiveness use asynchronous.
