推荐答案

如果要将数据表或数据集用作水晶报表的数据源，那么它非常容易.
只需将图像读入流中即可.将流添加为数据表中的列.将表设置为数据源.就是这样.

Hi,
If you are using datatable or dataset as datasource for crystal reports, then its very easy.
Just read the images into a stream. add the stream as a column in your data table. set the table as datasource. thats it.

//Just for an information I'm just typing this code
//Correct the syntactical errors
DataTable tbl;
MemoryStream ms;

//your data table filling logic
tbl.Columns.add("ImageColumn",typeof(string));//Fine tune this
ms = //load your image into stream
tbl.rows(0).setitem //to set the image data
//set this tbl as datasource for your report
