c# - "Could not find schema information for the element"- 但我的架构文件确实包含该元素的信息

Question

我正在尝试使用一个我没有源代码的应用程序。我正在尝试连接 XML 文件中的某些数据。我相信我的文件与应用程序所需的架构正确匹配，但我收到文件中每个元素的消息“无法找到该元素的架构信息”。我已经反编译应用程序代码并在 visual studio 中重新构建它，但我自己遇到了错误。

我将继续并转储代码...它很长，但我开始认为这是我的一个非常愚蠢的错误。

要导入的 XML:

我认为您缺少 namespace 。尝试:

<WorkOrders xmlns="http://www.manh.com/ILSNET/Interface">
