using CrystalDecisions.CrystalReports.Engine;

private const string REPORT_NAME = @"..\..\CrystalReportAnalysis.rpt";
private const string TEXT_OBJECT_NAME = @"Text1";

private void Form1_Load(object sender, System.EventArgs e)
{
report = new ReportDocument();

report.Refresh();

crvChart.ReportSource = report;
}

private void btnChangeText_Click(object sender, System.EventArgs e)
{
TextObject text;

text = GetTextObject(TEXT_OBJECT_NAME);

text.Text = "Hello, Haibo.NET!";

crvChart.RefreshReport();
}

private TextObject GetTextObject(string reportObjectName)
{
TextObject text;

// 按名称获取 ReportObject，将其转换为 TextObject，
//并返回此对象。
text = report.ReportDefinition.ReportObjects[reportObjectName] as TextObject;
if (text != null) return text;
else return null;
