使用 xsd.exe 生成 c# 文件，出现错误和警告

问题描述

这是我正在运行的命令:

This is the command i'm running:

xsd.exe -c -l:c# D:DocumentsDEVSARPilotDocsschemas6-141r26-141r2.xsd

这些是我得到的错误:

XSD 文件是从以下文档的附录 A 中复制/粘贴的:http://services.eoportal.org/portal/documents/06-141r2_Ordering_Services_for_Earth_Observation_Products_0.9.2.pdf

The XSD file was copy/pasted from Appendix A in the following document: http://services.eoportal.org/portal/documents/06-141r2_Ordering_Services_for_Earth_Observation_Products_0.9.2.pdf

推荐答案

您链接的 PDF 文档中包含的 XML 架构使用 <import> 元素引用了其他几个 XSD 文件.您需要下载这些额外的架构文件，并确保 <import> 元素中的路径引用指向本地计算机上的正确位置.

The XML Schema included in the PDF document you linked has references to several other XSD files using the <import> element. You will need to download these additional schema files and make sure that the path references in the <import> elements are pointing to the correct locations on your local computer.

如果您仍然收到错误，那是因为 xsd.exe 无法跟进外部引用.要解决此问题，请直接在命令行中指定所有必需的 XSD 文件，如下所示:

If you are still getting errors, it is because xsd.exe could not follow up on external references. To solve this issue, specify all the required XSD files directly on the command line as follows:

xsd.exe/c MySchema.xsd Import01.xsd Import02.xsd Include01.xsd Include02.xsd

其中 Import01.xsd、Import02.xsd、Include01.xsd 和 Include02.xsd 是通过导入引用的 XSD 文件并包含 MySchema.xsd 中的元素.

where Import01.xsd, Import02.xsd, Include01.xsd and Include02.xsd are XSD files referenced via import and include elements in MySchema.xsd.
