如何将PNG图像(作为内存流)呈现到.NET ReportViewer报表界面

public static string ConvertImageToBase64String(Image image)
{
    using (MemoryStream ms = new MemoryStream())
    {
        image.Save(ms, ImageFormat.Png);
        byte[] imageBytes = ms.ToArray();
        return Convert.ToBase64String(imageBytes);
    }
}

=System.Convert.FromBase64String(Parameters!ImageParameter.Value).ToArray()

 <Source>Database</Source>
 <Value>=System.Convert.FromBase64String(Parameters!ImageParameter.Value).ToArray()</Value>
  <MIMEType>image/png</MIMEType>
</Image>

  <DataType>String</DataType>
 <AllowBlank>true</AllowBlank>
  <Prompt>Image Parameter</Prompt>
</Parameter>

ReportViewer viewer = new ReportViewer();
viewer.ProcessingMode = ProcessingMode.Local;
viewer.LocalReport.ReportPath = "path_to_report.rdlc";
viewer.LocalReport.SetParameters(new ReportParameter("ImageParameter", base64String));
viewer.RefreshReport();
