How to use System.Drawing.Image in RDLC Image Control?

Question

Is it possible to use System.Drawing.Image in RDLC Image Control? All I read was 3 methods:

• database
• embedded resource
• external file

Thank you.

EDIT: Following this .NET or C # library for the CGM format (computer graphics metadata)? Now I got the image in System.Drawing.Image format and I want to display it as part of the report (as an image) --- what I want to do.

Answer 1

Not sure if this is what you are looking for, but if you have an image in your code and want to show it in a report, create a wrapper object that has a property that returns the image as a byte array and then gives an instance of this class -shells with a valid image in the report as a ReportDataSource source.

Something like:

  ReportDataSource logoDataSource = new ReportDataSource(); logoDataSource.Name = "LogoDS"; logoDataSource.Value = new List<LogoWrapper>() { yourLogoWrapper }; localReport.DataSources.Add(logoDS); 

In the report you can get an image as if from a database

  =First(Fields!LogoByteArrayProperty.Value, "LogoDS") 

The shell looks something like this:

  class LogoWrapper{ ... public byte[] LogoByteArrayProperty{ get{ // Return here the image data } } } 

I use this quite often. This has the advantage that I do not need to add an image to db or add it as a resource of each report. In addition, the application can tell which image should be used. Please note that this image format must be known from rdlc-engine. The final question is how to convert the system.drawing.image file to an array of bytes. I work with WPF and therefore I do not know. But I'm sure google will answer this question very reliably.

You can use the database source parameter along with the parameters to dynamically set the image source from byte arrays.

Code for:

 var param2 = new ReportParameter() { Name = "CompanyLogo", Values = { Convert.ToBase64String(*ByteArrayImageObject*) } }; ReportViewer1.LocalReport.SetParameters(param2); 

rdlc file:

1- Add text parameters 'CompanyLogo' and 'MIMEType'

2- Set the property of the image value to =System.Convert.FromBase64String(Parameters!CompanyLogo.Value)

3- Set the MIME Type property to

 =Parameters!MIMEType.Value 

4- Use the database as a source

Answer 3

I'm not quite sure what you want to do with this, but overall this is not possible. Shortcut management is just an image holder in RDLC files. These 3 parameters determine the location from where the image control receives an image that is displayed from a database, embedded resource, or external file. If you give me more information about what you want to achieve, I can give you some kind of solution.
