我有一个类似的xsd文件：

我有这样的代码：
using System;
using System.Collections;
using System.Xml;
using System.Xml.Schema;
namespace ConsoleApplication1
{
class XmlSchemaTraverseExample
{
static void Main()
{
// Add the customer schema to a new XmlSchemaSet and compile it.
// Any schema validation warnings and errors encountered reading or
// compiling the schema are handled by the ValidationEventHandler delegate.
XmlSchemaSet schemaSet = new XmlSchemaSet();
schemaSet.ValidationEventHandler += new ValidationEventHandler(ValidationCallback);
schemaSet.Add("http://www.w3.org/2001/XMLSchema", "C:\\Users\\ahmet.ulusoy\\Desktop\\pts_xml_schema_v_1_4.xsd");
schemaSet.Compile();
// Retrieve the compiled XmlSchema object from the XmlSchemaSet
// by iterating over the Schemas property.
XmlSchema customerSchema = null;
foreach (XmlSchema schema in schemaSet.Schemas())
{
customerSchema = schema;
}
// Iterate over each XmlSchemaElement in the Values collection
// of the Elements property.
foreach (XmlSchemaElement element in customerSchema.Elements.Values)
{
Console.WriteLine("Element: {0}", element.Name);
// Get the complex type of the Customer element.
XmlSchemaComplexType complexType = element.ElementSchemaType as XmlSchemaComplexType;
// If the complex type has any attributes, get an enumerator
// and write each attribute name to the console.
if (complexType.AttributeUses.Count > 0)
{
IDictionaryEnumerator enumerator =
complexType.AttributeUses.GetEnumerator();
while (enumerator.MoveNext())
{
XmlSchemaAttribute attribute =
(XmlSchemaAttribute)enumerator.Value;
Console.WriteLine("Attribute: {0}", attribute.Name);
}
}
// Get the sequence particle of the complex type.
XmlSchemaSequence sequence = complexType.ContentTypeParticle as XmlSchemaSequence;
// Iterate over each XmlSchemaElement in the Items collection.
foreach ( XmlSchemaElement childElement in sequence.Items)
{
Console.WriteLine("Element: {0}", childElement.Name);
}
}
}
static void ValidationCallback(object sender, ValidationEventArgs args)
{
if (args.Severity == XmlSeverityType.Warning)
Console.Write("WARNING: ");
else if (args.Severity == XmlSeverityType.Error)
Console.Write("ERROR: ");
Console.WriteLine(args.Message);
}
}
}
当我试图运行时，它给了我第一个元素'元素名称。 之后我怎么能拿其他两个xs：complexType name =“carrierType”和xs：complexType name =“productListType”及其子元素和属性？
我制作了这部分并要更新代码。
我还想创建一个包含这些数据和数据类型的泛型类。我该怎么办？
感谢您的进步。

如果您有上面的xsd文档，则可能需要这样的代码。
using System;
using System.Collections.Generic;

else OutputElements(all.Items[i] as XmlSchemaParticle);
}
Console.Out.WriteLine();
}
}
static void ValidationCallback(object sender, ValidationEventArgs args)
{
if (args.Severity == XmlSeverityType.Warning)
Console.Write("WARNING: ");

您可以针对更具体的案例进行改进。 例如attributegroup，group，vs ... 现在我也得到了xsd的泛型类。 现在，我将使用上面的xsd引用的xml设置泛型类（之前制作）。
通过这些操作，我将取消在我的项目中按节点读取xml节点的mecahnism。

对于已编译的XmlSchemaSet，我会使用以下集合来浏览全局内容（或命名，因为您正在寻找xs:complexType name="carrierType" and xs:complexType name="productListType"）：
对于所有其他人，例如属性组，组，符号，您需要浏览每个模式（对元素的方式）。
此外，您正在浏览PSVI属性。为了确保，也许对于其他阅读，它与“源”XSD不同。例如，AttributeUses与Attributes的不同之处可能会对不同的要求产生影响。
