菜鸟再一次问关于交互的问题
public void create() { database db = hostapplicationservices.workingdatabase; editor ed = application.documentmanager.mdiactivedocument.editor; try { using (transaction trans = db.transactionmanager.starttransaction()) { //prompts for each employee detail promptstringoptions prname = new promptstringoptions("enter employee name"); promptstringoptions prdiv = new promptstringoptions("enter employee division"); promptdoubleoptions prsal = new promptdoubleoptions("enter employee salary"); promptpointoptions prpos = new promptpointoptions("enter employee position or"); //add keywords when prompting for position prpos.keywords.add("name"); prpos.keywords.add("division"); prpos.keywords.add("salary"); //set the default values for each of these prname.defaultvalue = "earnest shackleton"; prdiv.defaultvalue = "sales"; prsal.defaultvalue = 10000.0f; //set conditions for prompting prpos.allownone = false; //do not allow null values //prompt results - set explicitly to null promptresult prnameres = null; promptresult prdivres = null; promptdoubleresult prsalres = null; promptpointresult prposres = null; //loop to get employee details. exit the loop when positon is entered while (prposres == null || prposres.status != promptstatus.ok) { //prompt for position prposres = ed.getpoint(prpos); if (prposres.status == promptstatus.keyword) //got a keyword { switch (prposres.stringresult) { case "name": //get employee name prname.allowspaces = true; prnameres = ed.getstring(prname); if (prnameres.status != promptstatus.ok) throw new system.exception("error or user cancelled"); break; case "division": //get employee division prdiv.allowspaces = true; prdivres = ed.getstring(prdiv); if (prdivres.status != promptstatus.ok) throw new system.exception("error or user cancelled"); break; case "salary": //get employee salary prsal.allownegative = false; prsal.allownone = true; prsal.allowzero = false; prsalres = ed.getdouble(prsal); if (prsalres.status != promptstatus.ok & prsalres.status != promptstatus.none) throw new system.exception("error or user cancelled"); break; } } if (prposres.status == promptstatus.cancel || prposres.status == promptstatus.error) throw new system.exception("error or user cancelled"); } //create the employee - either use the input value or the default value... string empname = (prnameres == null ? prname.defaultvalue : prnameres.stringresult); string divname = (prdivres == null ? prdiv.defaultvalue : prdivres.stringresult); double salary = (prsalres == null ? prsal.defaultvalue : prsalres.value); createemployee(empname, divname, salary, prposres.value); 在c#官方教程里面发现这么一段，我想模仿cad里面输入line的交互效果，即我输入一个点后回车，接着要求输入第二个点，请问如何改这段代码，或者有例子也好，大家帮帮我把
顶上去
应该不难，这是肯定可以实现的，你应该多研究研究，sdk的例子中也有很多好东西！
嗯，搞定了
如何搞定的??

以前我曾经arx编写过类似的程序，现在用.net还没有写过这种程序
可以用个死循环
