Use the following code to access the Parameters Object from a script.

使用以下代码从脚本访问参数对象。

object xafParameters = 
    ((DevExpress.XtraReports.UI.XtraReport)sender).Parameters["XafReportParametersObject"].Value

For instance, the following script displays the name of the Position selected in the parameters dialog as a label text.

例如，以下脚本将参数对话框中选择的位置的名称显示为标签文本。

private void ContactsBaseReport_BeforePrint(object sender, System.Drawing.Printing.PrintEventArgs e) {
    label1.Text ="";
    DevExpress.XtraReports.Parameters.Parameter param = 
        (DevExpress.XtraReports.Parameters.Parameter)((DevExpress.XtraReports.UI.XtraReport)sender).
            Parameters["XafReportParametersObject"];
    if(param != null) {
        MySolution.DemoParameters xafParameter = 
            (MySolution.DemoParameters)param.Value;
        label1.Text = xafParameter.ContactPosition.Name;
    }
}
