我已经使用 MySql 5.1 创建了一个水晶报告，现在当我在我的机器上运行时，它使用 XML（数据集在应用程序根文件夹中另存为 xml）。但是当应用程序安装在其他机器上时，它需要数据库登录。我怎样才能删除那个登录窗口？代码如下
cDataSet.DataSetName = "TimeDataSet";
cDataSet.WriteXml(Application.StartupPath
+ "\" + "TimeDSReport.xml", XmlWriteMode.WriteSchema);
ReportDocument report = new ReportDocument();
report.Load(Application.StartupPath + "\" + "TimeTracker.rpt");
crystalReportViewer1.ReportSource = report;

Make sure that the Name or the DataTable in "Typed DataSet" and the Name DataTable that you assign as "RecordSource" to crystal reprort must be same
确保“Typed DataSet”中的 Name 或 DataTable 与您指定为“RecordSource”给 Crystal reprort 的 Name DataTable 必须相同
Or if u are using directly from database Set the logon information in your code as below
或者，如果您直接从数据库中使用，请在您的代码中设置登录信息，如下所示
private void ConfigureCrystalReports()
{
rpt= new ReportDocument();
string reportPath = Server.MapPath("reportname.rpt");
rpt.Load(reportPath);
ConnectionInfo connectionInfo = new ConnectionInfo();
connectionInfo.DatabaseName = "Northwind";
connectionInfo.UserID = "sa";
connectionInfo.Password="pwd";
SetDBLogonForReport(connectionInfo,rpt);
CrystalReportViewer1.ReportSource = rpt;
}
