C# + ArcEngine 常用方法（不定时更新）

1、Arcengine调用GP服务，抛出异常方法

        
                   object sev = null;
                    try
                    {
                        Application.DoEvents();
                        gp.Execute(gpBuildPyramidsandStatistics, null);
                        Application.DoEvents();
                        Console.WriteLine(gp.GetMessages(ref sev));
                    }
                    catch (Exception ex)
                    {
                        // Print geoprocessing execution error messages.
                        MessageBox.Show(gp.GetMessages(ref sev));
                    }

    //ps:调用GP服务处理数据库中的数据，必须添加gp的环境变量workspace.http://www.ithao123.cn/content-7464230.html
    //Geoprocessor GP = new Geoprocessor(); 

    //string sWorkPath;   

    //IWorkspace pWork;   
    //if(pWork.Type == esriWorkspaceType.esriRemoteDatabaseWorkspace)
    //{  

          //sWorkPath = System.IO.Path.Combine(Application.StartupPath,"gpenvwk.sde");   
          //pWork.WorkspaceFactory.Create(Application.StartupPath,"gpenvwk.sde",pWork.ConnectionProperties,0);   
    //}
    //else
    //{ 
          //sWorkPath = pWork.PathName;   
    //}   
    //GP.SetEnvironmentValue("workspace",sWorkPath);   
    //GP.OverwriteOutput = true;
