ok, figured it out myself, wasn't that hard...

 If (TypeOf pLayer Is IFeatureLayer) Then
            Dim lay As IFeatureLayer
            Dim qu As String
            lay = CType(pLayer, IFeatureLayer)
            Dim def As IFeatureLayerDefinition = lay
            qu = def.DefinitionExpression
            Console.WriteLine(qu)
        End If

thanks ! the example was pretty helpfull.

one question more, is there a possibility to apply the
filter on the featuretofeilgeodatabase conversion tool ?
or how can i just convert those features which apply to
a query ?

Hi,
If you are using any Tool from Toolbox in ArcMap, tool is executed only on selected records in the Layer, if any. Otherwise, the same is executed on all the records.

Sry, i didn't mention i was using the .NET API.
I am using the toolbox tool FeaturetoFileGeodatabase via .NET.

But it copies all layers from the mxd, but unfortunately with all
datasets, even those which are not used, because my sql query for
this layer takes them out.

My question is now, if there is a possibility to select those datasets which
are ment to be copied, or do i have to copy all, and take out those, which
i don't want in the finished filegeodatabase ?!? 🙂

thanks for your patience !
