我需要解析组内 XSD 文件的限制，但我只能（在调试视图中）看到元素的名称（我也看到 "derived from restriction" ).但我需要 minInclusive 和 maxInclusive 值。

到目前为止，这是我的代码：

XmlSchema schema;

                        using (var reader = new StreamReader(Path.Combine(Environment.CurrentDirectory, "esquema.xsd")))
                        {
                            schema = XmlSchema.Read(reader, null);
                        }

                        XmlSchemaSet schemaSet = new XmlSchemaSet();
                        schemaSet.Add(schema);
                        schemaSet.Compile();

编译架构并进入调试模式后，我看不到我需要的东西。有什么线索吗？

此致

好的，假设我们想要获取架构的第 21 项（我的 XSD 片段就是这种情况）。以下是所有步骤（我还包含了动态打印，而不是检查所有可能的限制类型）。希望对以后的人有所帮助...

schema = schemaSet.Schemas().Cast<XmlSchema>().Single();
XmlSchemaGroup g = schema.Items[21] as XmlSchemaGroup;
XmlSchemaElement ge = g.Particle.Items[0] as XmlSchemaElement;
XmlSchemaSimpleType gef = ge.ElementSchemaType as XmlSchemaSimpleType;
XmlSchemaSimpleTypeContent gefc = gef.Content as XmlSchemaSimpleTypeContent;
XmlSchemaSimpleTypeRestriction re = gefc as XmlSchemaSimpleTypeRestriction;
XmlSchemaObjectCollection fac = re.Facets;
foreach (var restriccion in fac)
{
    Console.WriteLine(restriccion.GetType().ToString()+": {0}", (restriccion as dynamic).Value);
    //if (restriccion.GetType().Equals(typeof(XmlSchemaLengthFacet)))
    //{
    //    Console.WriteLine("length: {0}", (restriccion as XmlSchemaLengthFacet).Value);
    //}
    //else if (restriccion.GetType().Equals(typeof(XmlSchemaMinInclusiveFacet)))
    //{
    //    Console.WriteLine("minInclusive: {0}", (restriccion as XmlSchemaMinInclusiveFacet).Value);
    //}
    //else if (restriccion.GetType().Equals(typeof(XmlSchemaMaxInclusiveFacet)))
    //{
    //    Console.WriteLine("maxInclusive: {0}", (restriccion as XmlSchemaMaxInclusiveFacet).Value);
    //}
}
