以下代码在vb.net中生成这两个疑难解答提示 代码构建没有错误。本地窗口将OrderContext下的所有内容列为“Nothing”,0.0或“False”,当它停在试图设置address1的行上时。
“使用new关键字创建对象实例。”
“在调用方法之前检查以确定对象是否为null。”
Imports TPETest.com.nicusa.cdc.tpe2_ks
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim PEService As New PaymentEngineService
Dim OrderContext() As com.nicusa.cdc.tpe2_ks.WSOrderContext
OrderContext.customer.address.address1 = "1233 Test Dr."
OrderContext.customer.address.city = "City"
OrderContext.customer.address.state = "KS"
OrderContext.customer.address.zip = "66099"
OrderContext.attributes.SetValue("John Smith", 1)
OrderContext.attributes.SetValue("1233 Test Dr", 2)
答案 0 :(得分:3)
您需要将Option Strict On
放在模块的顶部。这有助于您确定将OrderContext
声明为数组,并且作为数组,它没有customer
或attributes
属性。
您可能想要输入
Dim OrderContext As New com.nicusa.cdc.tpe2_ks.WSOrderContext
