ms reportviewer 外联图片不显示的处理方式

在MS ReportViewer中加上LOGO,在开发过程中一切正常，部署到外网，LOGO不能显示

第一种方式:

图片地址格式化形如：

file:\\\c:\website\logo.jpg

或者

file:c:\website\logo.jpg

问题解决。

 

第二种方式:

            ReportViewer1.LocalReport.EnableExternalImages = true;
            ReportViewer1.LocalReport.Refresh();

Code

    public partial class Report : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                var path = "file:" + Server.MapPath("\\logo.png");
                ReportViewer1.LocalReport.EnableExternalImages = true;
                ReportViewer1.LocalReport.SetParameters(new Microsoft.Reporting.WebForms.ReportParameter("Logo1", path));
                ReportViewer1.LocalReport.Refresh();
            }
        }
    }
