Catching missing fields exception

[patwolf]

We use one report on multiple related but not the same datasets.
Now I would like to show the user the names of the fields which are referenced in the report but are missing in the current dataset in a nice error message.

So I got this code to view a report.
try
{
DataSet ds = GetDs();
var report = new StiReport();
report.Load(fpn);
report.Render(false);
}
catch (Exception ex)
{
When a field is missing I get this error:
c:\Users\..\AppData\Local\Temp\a3zl2axx.0.cs(75,33) : error CS1061: 'Reports.Report.humanuserDataSource' does not contain a definition for 'sg_department' and no extension method 'sg_department' accepting a first argument of type 'Reports.Report.humanuserDataSource' could be found (are you missing a using directive or an assembly reference?)c:\Users\..\AppData\Local\Temp\a3zl2axx.0.cs(80,50) : error CS1061: 'Reports.Report.humanuserDataSource' does not contain a definition for 'sg_department' and no extension method 'sg_department' accepting a first argument of type 'Reports.Report.humanuserDataSource' could be found (are you missing a using directive or an assembly reference?)

Is there a better Exception I could catch to get just the missing field name(s) please?

Thanks

Hello.

Unfortunately, there is no other exception.
You could parse the error message to get the missing field.

Thank you.
