在C#reportviewer中传递多个参数时出现问题 [英] Problem Passing more then one parameter in C# reportviewer

问题描述

我正在使用C#Reportviewer

我在将表单文本框中的多个参数传递到报表文本框中时遇到问题.

当我只经过一米时，它运行得很好

Hi,

I am using C# Reportviewer

I have a problem passing more than one parameter from my form textbox to report textbox.

When i only passed one meter like this it worked perfectly

this.reportViewer1.LocalReport.ReportPath = "Report2.rdlc";
     ReportParameter rp = new ReportParameter("InvoiceNumber", this.textBox2.Text);
     this.reportViewer1.LocalReport.SetParameters(new ReportParameter[] {rp});
          
     this.reportViewer1.RefreshReport();

但是现在，当我尝试像这样传递第二个参数时，它仅在我的报告中显示发票编号，而不是余额结转参数

But now as soon as i try passing a second parameter like this it only shows Invoice number in my report and not Balance brought forward parameter

this.reportViewer1.LocalReport.ReportPath = "Report2.rdlc";
    ReportParameter rp = new ReportParameter("InvoiceNumber", this.textBox2.Text);
    ReportParameter rpt = new ReportParameter("BalanceBroughtForward",      this.textBox5.Text);
    this.reportViewer1.LocalReport.SetParameters(new ReportParameter[] {rp});
    this.reportViewer1.LocalReport.SetParameters(new ReportParameter[] {rpt});
         
    this.reportViewer1.RefreshReport();

我的代码可能不适合传递2个参数.

有人可以在这件事上帮助我吗?

在此先感谢

Is my code maybe wrong for passing 2 parameter.

Can someone please assist me in this matter

Thanks in advance

推荐答案

我不确定-我目前无法对其进行测试-但是由于SetParamaters方法接受数组，因此一点都不明显:

I''m not sure - and I can''t test it at the moment - but since the SetParamaters method accepts an array, isn''t it all a bit obvious:

this.reportViewer1.LocalReport.SetParameters(new ReportParameter[] {rp});
this.reportViewer1.LocalReport.SetParameters(new ReportParameter[] {rpt});

成为:

this.reportViewer1.LocalReport.SetParameters(new ReportParameter[] {rp, rpt});
