geoprocessor test (转载——待测)

geoprocessing唯一难的地方就是参数，需要根据不同的情况设置，
我就以intersect方法为例，编程实现两个图层的intersect.
新建一个项目，添加引用，我们用的工具intersect是在AnalysisTools中的，在form中加一个button，然后实现其方法，如下，
别忘了添加命名空间

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using ESRI.ArcGIS.ArcMap;
using ESRI.ArcGIS.Controls;
using ESRI.ArcGIS.esriSystem;
using ESRI.ArcGIS.Geoprocessor;

namespace LandEnvaluation
{
    class gptest
    {
        //实现button click方法
        private void button1_Click(object sender, EventArgs e)
        {
            //构造Geoprocessor
            ESRI.ArcGIS.Geoprocessor.Geoprocessor gp = new ESRI.ArcGIS.Geoprocessor.Geoprocessor();
            //设置参数
            ESRI.ArcGIS.AnalysisTools.Intersect intersect = new ESRI.ArcGIS.AnalysisTools.Intersect();
            intersect.in_features = @"F:/foshan/Data/wuqutu_b.shp;F:/foshan/Data/world30.shp";
            intersect.out_feature_class = @"E:/intersect.shp";
            intersect.join_attributes = "ONLY_FID";
            //执行Intersect工具
            RunTool(gp, intersect, null);
        }

        private void RunTool(Geoprocessor geoprocessor, IGPProcess process, ITrackCancel TC)
        {
            // Set the overwrite output option to true
            geoprocessor.OverwriteOutput = true;

            try
            {
                geoprocessor.Execute(process, null);
                ReturnMessages(geoprocessor);

            }
            catch (Exception err)
            {
                Console.WriteLine(err.Message);
                ReturnMessages(geoprocessor);
            }
        }

        // Function for returning the tool messages.
        private void ReturnMessages(Geoprocessor gp)
        {
            string ms = "";
            if (gp.MessageCount > 0)
            {
                for (int Count = 0; Count <= gp.MessageCount - 1; Count++)
                {
                    ms += gp.GetMessage(Count);
                }
            }
        }
    }
}
