我尝试从具有上述结构的文件 XML 进行绑定，并希望显示如下：
TaskId | TaskTitle | TaskDesc | TaskLong | TaskLat | TaskTime | TaskQuestionId | TaskQuestionType | TaskQuestionTitle | TaskQuestionDesc | TaskQuestionAnwser
输出结果如：
1 | Task of Title | Task of Desc | Task Long | Task lat | Task Time | Task Question ID | Task Question Type | TaskQuestionTitle | Task Question Desc | Task Question Answer1, Task Question Answer2
我只有TaskQuestionAnswer没有出现的列。我不知道将其绑定并插入到我的可用表中，其中包含从 TaskId 到TaskQuestionDesc.
<taskQuestionAnswers>
<taskQuestionAnswer>Microsoft</taskQuestionAnswer>
<taskQuestionAnswer>Nokia Vietnam</taskQuestionAnswer>
<taskQuestionAnswer>Samsung</taskQuestionAnswer>
<taskQuestionAnswer>China Telecom</taskQuestionAnswer>
</taskQuestionAnswers>
我的问题意味着我不知道如何绑定并添加到我的表中。请帮我。非常感谢。
