将图像传递到CrystalReport [英] Passing images to a CrystalReport

问题描述

我正在使用VB.net代码将图像从本地磁盘传递到Crystal报告.我已经完成了将一个图像从本地驱动器传递到Crystal报表的操作，但是问题是我想从同一驱动器传递许多图像.我正在使用下面的代码传递图像:

I am passing images from my local disk to crystal reports using VB.net code. I have completed passing one image from my local drive to crystal reports, but the issue is I want to pass many images from the same drive. I am using the code below for passing the images:

' object of data row
     Dim drow As DataRow
     ' add the column in table to store the image of Byte array type
     dt.Columns.Add("Image", System.Type.GetType("System.Byte[]"))
     drow = dt.NewRow
     ' define the filestream object to read the image
     Dim fs As FileStream
     ' define te binary reader to read the bytes of image
     Dim br As BinaryReader
     ' check the existance of image
     If File.Exists(AppDomain.CurrentDomain.BaseDirectory & "10157.Jpg") Then
         ' open image in file stream
         fs = New FileStream(AppDomain.CurrentDomain.BaseDirectory & "10157.Jpg", FileMode.Open)
     Else ' if phot does not exist show the nophoto.jpg file
         fs = New FileStream(AppDomain.CurrentDomain.BaseDirectory & "FLYWELL.jpg", FileMode.Open)
     End If
     ' initialise the binary reader from file streamobject
     br = New BinaryReader(fs)
     ' define the byte array of filelength
     Dim imgbyte(fs.Length) As Byte
     ' read the bytes from the binary reader
     imgbyte = br.ReadBytes(Convert.ToInt32((fs.Length)))
     drow(0) = imgbyte       ' add the image in bytearray
     dt.Rows.Add(drow)       ' add row into the datatable
     br.Close()              ' close the binary reader
     fs.Close()              ' close the file stream
     Dim rptobj As New CrystalReport1    ' object of crystal report
     rptobj.SetDataSource(dt)
     CrystalReportViewer1.ReportSource = rptobj  'set the report source
