Using ArcGIS 10.4.1 ArcObjects with geoprocessing. I have an input feature class with 100s of polygons and also one raster. I iterate through each polygon and clip the raster and then do additional work. It has performed well up to today. It seems some our polygons are outside of the raster area.
So my code in VB.NET looks like this:
'create an IVariantArray to hold the parameter values.
Dim parameters As IVariantArray = New VarArray
'populate the variant array with parameter values.
parameters.Add(inSurfaceFullName) 'input surface
parameters.Add("") 'rectangle to be used as the clipper

I have been looking in the ESRI SDK for a pre-process where I can check if the polygon intersects the raster with a True/False as the result. Is that something that exists? Or another way to check the intersection of a geometry with a raster?
The only thing I have tried is to check if the extents intersect but I can see where this may fail. For example a circle geometry just at the corner of the raster. the envelopes will intersect but the geometry and raster will not.

First you can start by obtaining the extent of the raster (IRasterDataset) with IGeodataset.Extent which returns an IEnvelope which can be cast as an IRelationalOperator.
For each polygon geometry (IGeometry) then test your relational operator for Disjoint which is quicker than trying to find Overlaps. If IRelationalOperator.Disjoint then the polygon does not intersect the extent of the raster so skip to the next one.
Thanks for the input. As per my post "The only thing I have tried is to check if the extents intersect but I can see where this may fail. For example a circle geometry just at the corner of the raster. the envelopes will intersect but the geometry and raster will not."

I can't speak to vb.net, but you could do a raster to polygon conversion and check against that output. If that's too expensive with a million tiny polygons then convert to a boolean raster before polygonizing.

That method has merit @mikewatt, if you have a spatial analyst license you can perform raster to polygon on IsNull(your_raster) then with the query filter of "GRIDCODE = 0" delete searched rows (help.arcgis.com/en/sdk/10.0/arcobjects_net/componenthelp/… FeatureClass implements ITable) to remove the null portion... this is more time consuming but ensures there is actual data in the image the polygon intersects.

Why not just catch and handle the error?

Well I may have many polygons and they can be large. So wouldn't I be doing an extract twice for each polygon that is within the raster?

So test the extents are not disjoint, then do the clip and catch the exception where the envelopes intersect but the geometry and raster don't.
