使用xsd.exe生成c#文件，获取错误和警告

Question

这是我正在运行的命令：

xsd.exe -c -l:c# D:\Documents\DEV\SARPilot\Docs\schemas\06-141r2\06-141r2.xsd

以下是我得到的错误：

XSD文件在以下文档中从附录A复制/粘贴：http://services.eoportal.org/portal/documents/06-141r2_Ordering_Services_for_Earth_Observation_Products_0.9.2.pdf

Answer 1

您链接的PDF文档中包含的XML Schema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。

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

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MySchema.xsd中的import和include元素引用的XSD文件。

Answer 2

我也遇到了同样的问题，我是这样解决的：

1)将xsd中引用的所有用于代码生成的xsd文件复制到相同的位置，即"C:\Projects\Project1\Documents\xsds\strucutre".2)在执行xsd.exe时提到了所有引用的xsd文件：

C:\Projects\Project1\Documents\xsds\strucutre>"C:\Program文件( /o:C:\Projects\Project1\Documents\ClassStructure )\Microsoft\x86\v7.0A\Bin\NETFX4.0 Tools\xsd“structure.xsd RefXsd1.xsd RefXsd2.xsd RefXsd3.xsd /c SDK

在文件夹C:\Projects\Project1\Documents\ClassStructure.下生成了一个包含xsds中提到的实体的c-sharp文件。

希望这能有所帮助！
