XmlReader..::.SchemaInfo Property

Gets the schema information that has been assigned to the current node as a result of schema validation.

Namespace: System.Xml
Assembly: System.Xml (in System.Xml.dll)

Syntax

Visual Basic (Declaration)

Public Overridable ReadOnly Property SchemaInfo As IXmlSchemaInfo

Visual Basic (Usage)

Dim instance As XmlReader
Dim value As IXmlSchemaInfo

value = instance.SchemaInfo

public virtual IXmlSchemaInfo SchemaInfo { get; }

Visual C++

public:
virtual property IXmlSchemaInfo^ SchemaInfo {
    IXmlSchemaInfo^ get ();
}

JScript

public function get SchemaInfo () : IXmlSchemaInfo

Property Value

Type: System.Xml.Schema..::.IXmlSchemaInfo
An IXmlSchemaInfo object containing the schema information for the current node. Schema information can be set on elements, attributes, or on text nodes with a non-null ValueType (typed values).
If the current node is not one of the above node types, or if the XmlReader instance does not report schema information, this property returns nullNothingnullptra null reference (Nothing in Visual Basic).
If this property is called from an XmlTextReader or an XmlValidatingReader object, this property always returns nullNothingnullptra null reference (Nothing in Visual Basic). These XmlReader implementations do not expose schema information through the SchemaInfo property.

Note:
If you have to get the post-schema-validation information set (PSVI) for an element, position the reader on the end tag of the element, rather than the start tag. You get the PSVI through the SchemaInfo property of a reader. The validating reader that is created through Create with the ValidationType property set to Schema has complete PSVI for an element only when the reader is positioned on the end tag of an element.

Note:

If you have to get the post-schema-validation information set (PSVI) for an element, position the reader on the end tag of the element, rather than the start tag. You get the PSVI through the SchemaInfo property of a reader. The validating reader that is created through Create with the ValidationType property set to Schema has complete PSVI for an element only when the reader is positioned on the end tag of an element.

Remarks

The IXmlSchemaInfo interface exposes a subset of the Post Schema Validation Infoset (PSVI) associated with an XML node.
