jacob操作dll時，怎么取ref回調(diào)函數(shù)返回的值？如果有其他更好的方法操作DLL，求指導(dǎo)啊~~DLL方法：int BUSINESS_HANDLEAPI(string businessCode, string inputData, ref string outData);我現(xiàn)在是這樣寫的ActiveXComponent dotnetCom = null;dotnetCom = new ActiveXComponent("CInterface.Handler");String outData="";Variant var = Dispatch.call(dotnetCom,"BUSINESS_HANDLE","00","QXWEB",outData);System.out.println("執(zhí)行結(jié)果："+var.toString());System.out.println("返回的值："+outData);

TA貢獻(xiàn)1831條經(jīng)驗獲得超9個贊

Variant outData = new Variant("value", true); //這樣應(yīng)該就是ref string了
Variant var = Dispatch.call(dotnetCom,"BUSINESS_HANDLE","00","QXWEB",outData);
System.out.println("返回的值："+outData.getStringRef());
