我认为您需要更改 XmlSampleGenerator.dll

I think you need to change the XmlSampleGenerator.dll

private bool GenerateElement(XmlSchemaElement e, bool root, InstanceGroup parentElem, XmlSchemaAny any) {
         XmlSchemaElement eGlobalDecl = e;
         bool flagCached = false;
         if (!e.RefName.IsEmpty) {
               eGlobalDecl = (XmlSchemaElement)schemaSet.GlobalElements[e.QualifiedName];
         }
         if (!eGlobalDecl.IsAbstract) {
               InstanceElement elem = (InstanceElement)elementTypesProcessed[eGlobalDecl];
               if (elem != null) {
                   Debug.Assert(!root);
                   if (any == null && e.MinOccurs > 0) { //If not generating for any or optional ref to cyclic global element
                       decimal occurs = e.MaxOccurs;
                       if (e.MaxOccurs >= maxThreshold) {
                           occurs = maxThreshold;
                       }
                       if (e.MinOccurs > occurs) {
                           occurs = e.MinOccurs;
                       }
                       elem = elem.Clone(occurs);
                       parentElem.AddChild(elem);
                       flagCached = true;
                   }
               }
               else
               {
                   elem = new InstanceElement(eGlobalDecl.QualifiedName);

               else {
                   if(!flagCached)
                   parentElem.AddChild(elem);
                   flagCached = false;
               }
               //Get minOccurs, maxOccurs alone from the current particle, everything else pick up from globalDecl
               if (any != null) { //Element from any
                   elem.Occurs = any.MaxOccurs >= maxThreshold ? maxThreshold : any.MaxOccurs;
                   elem.Occurs = any.MinOccurs > elem.Occurs ? any.MinOccurs : elem.Occurs;
               }
               else {

               if (eGlobalDecl.ElementSchemaType == AnyType) {
                   elem.ValueGenerator = XmlValueGenerator.AnyGenerator;
               }
               else {
                   XmlSchemaComplexType ct = eGlobalDecl.ElementSchemaType as XmlSchemaComplexType;
                   if (ct != null) {
                       if(!elementTypesProcessed.ContainsKey(eGlobalDecl)) elementTypesProcessed.Add(eGlobalDecl, elem);
                       if (!ct.IsAbstract) {
                           elem.IsMixed = ct.IsMixed;
                           ProcessComplexType(ct, elem);

                   }

                       elem.ValueGenerator = XmlValueGenerator.CreateGenerator(eGlobalDecl.ElementSchemaType.Datatype, listLength);
                   }
               }
               if (elem.ValueGenerator != null && elem.ValueGenerator.Prefix == null) {
                   elem.ValueGenerator.Prefix = elem.QualifiedName.Name;
