How can I input several files for tools in arcobject?

[InsuHong1]

Hi,

How can I input several shp files or feature classes for tools?

for example, if I implement code for 'Intersect' tool to intersect shp files: testA.shp, testB.shp

Intersect Inter = new Intersect(); Inter.in_features = features;  Inter.out_feature_class = 'result.shp';  gp.Execute(Inter, null);

How can I input 'testA.shp' and 'testB.shp' as parameters for 'in_features' ?

I know how input single object: @"C:\data\aaa.shp" . like this. I know.

But I cannot find any document for multiple features. other answers just repeat see reference and sample. I saw them, but I could not figure out because all of samples only showed single parameter!

I tried 'List' of files, 'Array' of files, and just , or ; but all of them failed to compile.

Not sure why you are using single quotes in C#...  They are for defining a char (char i = 'i';) Passing in a string array should work fine.  If it is not compiling check if you have option strict on.  If you do it is a good thing, it just means you can't pass a string array into a property expecting an object without doing as explicit type conversion.  The following compiles ok on my machine, I haven't run it because I don't have the shapefiles and can't be bothered right now.

      
      Geoprocessor gp = new Geoprocessor();
      Intersect Inter = new Intersect();
      string[] features = {"c:\\shape1.shp", "c:\\shape2.shp"} ; 
      Inter.in_features =  features as object;
      Inter.out_feature_class = "c:\\result.shp"; 
      gp.Execute(Inter, null);

Here's an example that ESRI support sent to me on using several inputs for the Intersect tool

ESRI.ArcGIS.Geoprocessor.Geoprocessor GP = new ESRI.ArcGIS.Geoprocessor.Geoprocessor(); GP.OverwriteOutput = true; IGPUtilities2 gpUtils = new GPUtilitiesClass(); IFeatureClass inFeature1 = gpUtils.OpenFeatureClassFromString(@"E:\Test.gdb\states"); IFeatureClass inFeature2 = gpUtils.OpenFeatureClassFromString(@"E:\Test.gdb\us_rivers"); IGpValueTableObject vt = new GpValueTableObjectClass(); //vt.SetColumns(1); vt.SetColumns(2); object weight; weight = 1 as object; object obj1 = inFeature1; vt.AddRow(ref obj1); vt.SetValue(0, 1, ref weight); object obj2 = inFeature2; vt.AddRow(ref obj2); vt.SetValue(1, 1, ref weight); ESRI.ArcGIS.AnalysisTools.Intersect intersect = new ESRI.ArcGIS.AnalysisTools.Intersect(); intersect.in_features = vt; intersect.out_feature_class = "E:\testout.shp"; GP.Execute(intersect, null);

agray: I don't know why, your code did not work my PC. anyway, thanks.

kenbuja: yours is worked!!!!!  Thank you. I reaally appriciate.

Glad to help. Don't forget to mark the question as answered.

Strange...

code from kenbuja worked fine with Intersect tool, but it failed with other tools, such as Merge, FeatureToPolygon.


This drives me crazy. I struck this damn problem 2 weeks..

I completed lost.

What's the problem. Somebody please help me.
