如何将外部 xsd 导入另一个 xsd？

Question

我正在尝试从 xsd 下面生成类，但它在生成类时抛出了几个错误。

我正在使用以下命令从 xsd 下面生成类： xsd <Schemaname>.xsd /classes

显示错误如下： - Error while generating classes for schema TransactionHeader. The element 'http://www.example.com/Category/header:TransactionHeader' is missing.

<?xml version="1.0" encoding="UTF-8"?>

            </xs:documentation>
        </xs:annotation>
    </xs:element>
</xs:schema>

我完全不知道如何使用 xsd 类型。我该如何解决这个问题，以便为所有 xsd 生成类，包括引用的

我使用下面的命令为 Assignment.xsd

生成类

xsd.exe /c Assignment.xsd

但是当直接使用如下命令添加外部引用xsd名称时，类生成成功。

xsd.exe /c Assignment.xsd TransactionHeader.xsd.xsd CommonTypes.xsd

如何将外部 xsd 导入另一个 xsd？

c#

xsd

xsd.exe

xsd-1.1
