示例

下面的代码示例将发现文档从 “” http://localhost/example_Write2_cs.vsdisco 读入 XmlTextReader。

// Create a DiscoveryDocument.
DiscoveryDocument^ myDiscoveryDocument = gcnew DiscoveryDocument;

// Create an XmlTextReader with the sample file.
XmlTextReader^ myXmlTextReader = gcnew XmlTextReader(
   "http://localhost/example_Write2_cs.disco" );

// Read the given XmlTextReader.
myDiscoveryDocument = DiscoveryDocument::Read( myXmlTextReader );

FileStream^ myFileStream = gcnew FileStream(
   "log.txt",FileMode::OpenOrCreate,FileAccess::Write );
StreamWriter^ myStreamWriter = gcnew StreamWriter( myFileStream );

XmlTextWriter^ myXmlTextWriter = gcnew XmlTextWriter( myStreamWriter );
myDiscoveryDocument->Write( myXmlTextWriter );

myXmlTextWriter->Flush();
myXmlTextWriter->Close();

// Display the contents of the DiscoveryDocument on the console.
FileStream^ myFileStream1 = gcnew FileStream(
   "log.txt",FileMode::OpenOrCreate,FileAccess::Read );
StreamReader^ myStreamReader = gcnew StreamReader( myFileStream1 );

// Set the file pointer to the beginning.
myStreamReader->BaseStream->Seek( 0, SeekOrigin::Begin );
Console::WriteLine( "The contents of the DiscoveryDocument are: " );
while ( myStreamReader->Peek() > -1 )
{
   Console::WriteLine( myStreamReader->ReadLine() );
}
myStreamReader->Close();

// Create a DiscoveryDocument.
DiscoveryDocument myDiscoveryDocument = new DiscoveryDocument();

// Create an XmlTextReader with the sample file.
XmlTextReader myXmlTextReader = new
   XmlTextReader( "http://localhost/example_Write2_cs.disco" );

// Read the given XmlTextReader.
myDiscoveryDocument = DiscoveryDocument.Read( myXmlTextReader );

FileStream myFileStream = new
   FileStream( "log.txt", FileMode.OpenOrCreate, FileAccess.Write );
StreamWriter myStreamWriter = new StreamWriter( myFileStream );

XmlTextWriter myXmlTextWriter = new XmlTextWriter( myStreamWriter );
myDiscoveryDocument.Write( myXmlTextWriter );

myXmlTextWriter.Flush();
myXmlTextWriter.Close();

// Display the contents of the DiscoveryDocument on the console.
FileStream myFileStream1 = new
   FileStream( "log.txt", FileMode.OpenOrCreate, FileAccess.Read );
StreamReader myStreamReader = new StreamReader( myFileStream1 );

// Set the file pointer to the beginning.
myStreamReader.BaseStream.Seek(0, SeekOrigin.Begin);
Console.WriteLine( "The contents of the DiscoveryDocument are:" );
while ( myStreamReader.Peek() > -1 )
{
   Console.WriteLine( myStreamReader.ReadLine() );
}
myStreamReader.Close();

' Create a DiscoveryDocument.
Dim myDiscoveryDocument As New DiscoveryDocument()

' Create an XmlTextReader with the sample file.
Dim myXmlTextReader As _
    New XmlTextReader("http://localhost/example_Write2_vb.disco")

' Read the given XmlTextReader.
myDiscoveryDocument = DiscoveryDocument.Read(myXmlTextReader)

Dim myFileStream As _
    New FileStream("log.txt", FileMode.OpenOrCreate, FileAccess.Write)
Dim myStreamWriter As New StreamWriter(myFileStream)

Dim myXmlTextWriter As New XmlTextWriter(myStreamWriter)
myDiscoveryDocument.Write(myXmlTextWriter)

myXmlTextWriter.Flush()
myXmlTextWriter.Close()

' Display the contents of the DiscoveryDocument on the console.
Dim myFileStream1 As New FileStream( _
    "log.txt", FileMode.OpenOrCreate, FileAccess.Read)
Dim myStreamReader As New StreamReader(myFileStream1)

' Set the file pointer to the beginning.
myStreamReader.BaseStream.Seek(0, SeekOrigin.Begin)
Console.WriteLine("The contents of the DiscoveryDocument are: ")
While myStreamReader.Peek() > - 1
   Console.WriteLine(myStreamReader.ReadLine())
End While
myStreamReader.Close()

Public Shared Function Read (xmlReader As XmlReader) As DiscoveryDocument

参数

xmlReader

XmlReader

将从其中读取 XmlReader 的 DiscoveryDocument。

返回

DiscoveryDocument

DiscoveryDocument，它包含所传递的 XmlReader 中的发现文档的内容。

示例

如果 CanRead 属性为 true，则下面的代码示例读取发现文档的内容。

if ( DiscoveryDocument::CanRead( myXmlTextReader ) == true )
      
// Read the given XmlTextReader.
myDiscoveryDocument = DiscoveryDocument::Read( myXmlTextReader );
else
      Console::WriteLine( "The supplied file is not readable" );

// Check whether the given XmlTextReader is readable.
if( DiscoveryDocument.CanRead( myXmlTextReader ) == true )
{
   // Read the given XmlTextReader.
   myDiscoveryDocument = DiscoveryDocument.Read( myXmlTextReader );
}
else
{
   Console.WriteLine( "The supplied file is not readable" );
}

' Check whether the given XmlTextReader is readable.
If DiscoveryDocument.CanRead(myXmlTextReader) = True Then
   ' Read the given XmlTextReader.
   myDiscoveryDocument = DiscoveryDocument.Read(myXmlTextReader)
Else
   Console.WriteLine("The supplied file is not readable")
