无法从'system.drawing.image'转换为'string' [英] Cannot convert from 'system.drawing.image' to 'string'

问题描述

I want to pass PictureBox to rdlc report, but I get this error

[cannot convert from 'System.Drawing.Image' to 'string'][1]


         private void ReportPrintDes_Load(object sender, EventArgs e)
        {
            pictureBox1.Image = picQr;
            pictureBox2.Image = picQr2;


            reportViewer1.LocalReport.EnableExternalImages = true;
            ReportParameter img = new ReportParameter("img", (pictureBox1));
             this.reportViewer1.RefreshReport();
          



        }


Is there any way to change PictureBox(image) to string, or another way to pass PictureBox to rdlc report?

推荐答案

请参见此处示例：如何在RDLC报告中添加外部图像（C＃） [ ^ ]

您可以像这样首先保存图像：

See example here: How to add an external image in RDLC Report (C#)[^]
You can save the image first like this:

pictureBox1.Image.Save(@"C:\Temp\Mypic.jpg",ImageFormat.Jpeg);
