由于保护级别，报告查看器无法访问

Question

将TextBox值传递给Crystal Report时出现此错误。我该如何解决这个问题？

  

错误1＆＃39; Project.Print1.crystalReportViewer1＆＃39;由于其保护级别C：\ Users \ Yourlaks \ Desktop \ U1 \ Project \ Project \ Callcul.cs 307 16 Project

无法访问

此代码从我的文本框中获取要在报告中显示的值，包括错误行：

private void buttonX3_Click(object sender, EventArgs e)
{
    Print1 pr = new Print1();
    CrystalReport1 cr1 = new CrystalReport1();
    TextObject to1 = (TextObject)cr1.ReportDefinition.Sections["Section4"].ReportObjects["Txt1"];
    to1.Text = textBoxX1.Text;
    pr.crystalReportViewer1.ReportSource = cr1;
    pr.Show();
}
