XmlSchemaCollection.Item[String] 属性

定义

命名空间:

System.Xml.Schema

程序集:

System.Xml.ReaderWriter.dll

Source:

XmlSchemaCollection.cs

获取与给定的命名空间 URI 关联的 XmlSchema。

public:
 property System::Xml::Schema::XmlSchema ^ default[System::String ^] { System::Xml::Schema::XmlSchema ^ get(System::String ^ ns); };

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

参数

ns

String

与要返回的架构关联的命名空间 URI。 这通常会是架构的 targetNamespace。

属性值

XmlSchema

与命名空间 URI 关联的 XmlSchema；如果没有加载与给定的命名空间关联的架构，或者，如果该命名空间与 XDR 架构关联，则为 null。

示例

以下示例检查集合中是否存在架构。 如果是，则显示架构。

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
