ArcEngine 调用GP里面的Merge工具

public static Boolean Merge(String[] inputs,String output)
        {
            Geoprocessor gp = new Geoprocessor();
            gp.OverwriteOutput = true;

            int strSize = inputs.Count();
            String tempStr = "\""+inputs[0]+"";
            for (int i = 1; i < strSize-1; i++)
            {
                tempStr += ";" + inputs[i]+"";
            }
            tempStr += ";" + inputs[strSize - 1] + "\"";
            MessageBox.Show("input: "+ tempStr);
            ESRI.ArcGIS.DataManagementTools.Merge merge = new ESRI.ArcGIS.DataManagementTools.Merge();
            merge.inputs = tempStr;
            merge.output = output;
            try
            {
                gp.Execute(merge, null);
            }
            catch (COMException e)
            {
                string str = "";
                for (int i = 0; i < gp.MessageCount; i++)
                {
                    str += gp.GetMessage(i);

                }
                MessageBox.Show(str);
                return false;
            }
            
            return true;
        }

主要需要注意下 input参数的怎么组织问题；跟python脚本里面组织参数的形式有点不一样！
