topic Returning a feature class as an output parameter ArcObjects Toolbox Tool in ArcObjects SDK Questions https://community.esri.com/t5/arcobjects-sdk-questions/returning-a-feature-class-as-an-output-parameter/m-p/69635#M1872 <HTML><HEAD></HEAD><BODY><SPAN>Hi,</SPAN><BR /><BR /><SPAN>I've been working on writing some ArcObjects tools for use in a toolbox that will ultimately be published to ArcGIS Server. I'm having some trouble in an attempt to return a feature class as a parameter. I've attempted to use the SetParamaterValue() in the IGeoProcessor2 interface to return it, however it will consistently crash the toolbox in Arc when I set it to expect an output feature class. I can't seem to find any documentation for doing this in ArcObjects .NET aside from returning strings. I know it can be done in ArcPy, so I assume there is a way in ArcObjects .NET.</SPAN></BODY></HTML> Mon, 14 Nov 2011 17:33:24 GMT AaronHigh 2011-11-14T17:33:24Z Returning a feature class as an output parameter ArcObjects Toolbox Tool https://community.esri.com/t5/arcobjects-sdk-questions/returning-a-feature-class-as-an-output-parameter/m-p/69635#M1872 <HTML><HEAD></HEAD><BODY><SPAN>Hi,</SPAN><BR /><BR /><SPAN>I've been working on writing some ArcObjects tools for use in a toolbox that will ultimately be published to ArcGIS Server.
