Contains(String)

Source:

XmlSchemaCollection.cs

Gets a value indicating whether a schema with the specified namespace is in the collection.

public:
 bool Contains(System::String ^ ns);

public bool Contains (string? ns);

member this.Contains : string -> bool

Public Function Contains (ns As String) As Boolean

Parameters

ns

String

The namespace URI associated with the schema. For XML Schemas, this will typically be the target namespace.

Returns

Boolean

true if a schema with the specified namespace is in the collection; otherwise, false.

Examples

The following example checks to see if a schema is in the collection. If it is, it displays the schema.

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
