public System.Xml.Schema.XmlSchema? this[string? ns] { get; }

member this.Item(string) : System.Xml.Schema.XmlSchema

Default Public ReadOnly Property Item(ns As String) As XmlSchema

參數

ns

String

與您要傳回的結構描述相關聯的命名空間 URI。 這通常是結構描述的 targetNamespace。

範例

下列範例會檢查架構是否在集合中。 如果是，則會顯示架構。

if ( xsc->Contains( "urn:bookstore-schema" ) )
{
   XmlSchema^ schema = xsc[ "urn:bookstore-schema" ];
   StringWriter^ sw = gcnew StringWriter;
   XmlTextWriter^ xmlWriter = gcnew XmlTextWriter( sw );
   xmlWriter->Formatting = Formatting::Indented;
   xmlWriter->Indentation = 2;
   schema->Write( xmlWriter );
   Console::WriteLine( sw );
}

if (xsc.Contains("urn:bookstore-schema"))
{
  XmlSchema schema = xsc["urn:bookstore-schema"];
  StringWriter sw = new StringWriter();
  XmlTextWriter xmlWriter = new XmlTextWriter(sw);
  xmlWriter.Formatting = Formatting.Indented;
  xmlWriter.Indentation = 2;
  schema.Write(xmlWriter);
  Console.WriteLine(sw.ToString());
}

If xsc.Contains("urn:bookstore-schema") Then
    Dim schema As XmlSchema = xsc("urn:bookstore-schema")
    Dim sw As New StringWriter()
    Dim xmlWriter As New XmlTextWriter(sw)
    xmlWriter.Formatting = Formatting.Indented
    xmlWriter.Indentation = 2
    schema.Write(xmlWriter)
    Console.WriteLine(sw.ToString())
End If

重要

類別 XmlSchemaCollection 已在 .NET Framework 2.0 版中過時，且已由 XmlSchemaSet 類別取代。
