【问题描述】：
我从表单上的文本框中获取信息，然后通过一种方法将其传递给一个类（仍在学习。）我发送的信息通过就好了。在我的代码下面，我按照它们的工作方式列出了它们。
第一步是获取通过的数字（第一组代码）。然后将其传递给具有方法的类，该方法设置为用户控件（第二组代码）。它通过这些步骤，然后将其带到另一个类（第三组代码）以返回我在框内需要的值。然后它又回去了，应该把它贴在盒子里，然而，事实并非如此。
我还是个新手，需要一些帮助。
谢谢，
吉米·迪恩

【问题讨论】：
-
@TheGeneral 数据返回结果，但这些结果不会发布在列表框中。列表框保持空白。我不认为我对此很清楚，我深表歉意。是的，field16 是一个数字。
-
Information的结构是什么 -
不知道是这里的代码还是你的真实代码中的拼写错误，但是你需要在accountVerification和ORDER之间留一个空格{accountVerification}ORDER
-
@TheGeneral，我已经用信息更新了代码
-
@Steve 不知道为什么，但我没有得到任何错误，因为它没有被隔开，并且无论有没有空格都返回相同的结果。
