當使用SSRS技術來布置報表,可能使用MS自帶的ReportViewer控件來讀取報表.

它分為Web和Windows兩種版本;此處Web版.

ServerReport.ReportServerCredentials屬性的類型為Microsoft.Reporting.WebForms.IReportServerCredentials,它可提供三種認證方式所需的證書(Credential):

?1) Form認證證書(GetFormsCredentials);

?2) 扮演認證證書(ImpersonationUser);

?3) 網絡認證證書(NetworkCredentials).

?

?當報表的服務器端使用網絡認證時,需要實現NetworkCredentials接口,而且必須將GetFormsCredentials()接口的返回值設置為False,否則會導致論證失敗.

?示例代碼如下:
