在Form1窗體中，從工具箱拖出一個Crystal Report Viewer控件，雙擊Form窗體，是雙擊Form窗體，不是Crystal Report Viewer，在后臺的Form_Load事件中寫入如下代碼：
private void Form1_Load(object sender, EventArgs e)
{
string connStr = "Data Source=.\\SqlExpress;Initial Catalog=dbTest;User ID=sa;Password=test";
SqlConnection conn = new SqlConnection(connStr);
conn.Open();
try
{
string sql = "SELECT * FROM Customer where email!='test@gmail.com'";
SqlDataAdapter sda = new SqlDataAdapter(sql, conn);
DataSet ds = new DataSet();
sda.Fill(ds, "tmpTable");
string reportPath = System.Windows.Forms.Application.StartupPath + @"\CrystalReport1.rpt";
ReportDocument rd = new ReportDocument();
rd.Load(reportPath);
rd.SetDataSource(ds.Tables[0].DefaultView);
this.crystalReportViewer1.ReportSource = rd;
}
catch (Exception ex)
{
throw new Exception(ex.Message.ToString());
}
finally
{
conn.Close();
}
}
