biztalk映射器出错。指数超出范围。必须是非负数且小于集合的大小 [英] Error in biztalk mapper. Index out of range. Must be non-negative and less than the size of the collection

问题描述

在我的BizTalk应用程序（2013）中，我有一个映射到目标模式的源模式。

In my BizTalk application (2013), I have a source schema mapped to the destination schema.

映射器工作正常，直到我更改了其中一个的属性源模式中的元素从'optional'到required'

The mapper was working fine until I changed the property of one of the element on source schema from 'optional' to required'

当我更改为'required'时，构建失败，mapper中出现错误：'索引超出范围。必须是非负数且小于集合的大小。

When I changed to 'required', the build fails with an error in mapper which says: 'Index out of range. Must be non-negative and less than the size of the collection.

为什么我会收到此错误以及如何修复？

Why do I get this error and how to fix it?

我们可以通过直接在地图源（.btm）文件中修改
mapsource 元素的属性来修改BizTalk Mapper的某些默认行为。

We can modify certain default behaviors of BizTalk Mapper by modifying attributes of the mapsource element directly in a map source (.btm) file.

从上面的描述中，我不确定你修改了哪个元素，我几乎无法进行精确的故障排除。在我看来，你可以按照这个

指南使用< mapsource>管理默认的Mapper行为。

From your description above, I'm not sure which element you modified, and I can hardly give precise troubleshooting. In my opinion, you could follow this guide to manage default Mapper Behavior using <mapsource>.

祝你有个美好的一天。
