IFragmentCapableXmlDictionaryWriter.WriteFragment 方法

定義

命名空間:

System.Xml

組件:

System.Runtime.Serialization.Xml.dll

Source:

IFragmentCapableXmlDictionaryWriter.cs

將 XML 片段寫入至寫入器的基礎資料流。

public:
 void WriteFragment(cli::array <System::Byte> ^ buffer, int offset, int count);

public void WriteFragment (byte[] buffer, int offset, int count);

abstract member WriteFragment : byte[] * int * int -> unit

Public Sub WriteFragment (buffer As Byte(), offset As Integer, count As Integer)

參數

buffer

Byte[]

要寫入的緩衝區。

offset

Int32

要在 buffer 中進行寫入的起始位置。

count

Int32

要寫入至 buffer 的位元組數目。

範例

MemoryStream stream = new MemoryStream();  
MemoryStream fragmentStream = new MemoryStream();  
XmlDictionaryWriter writer = XmlDictionaryWriter.CreateTextWriter(stream);  
IXmlFragmentCapableXmlDictionaryWriter fragmentWriter = writer as IXmlFragmentCapableXmlDictionaryWriter;  
if (fragmentWriter == null || !fragmentWriter.CanFragment)  
{  
Console.WriteLine("This writer doesn't support fragments");  
return;  
}  
writer.WriteStartElement("Root");  
fragmentWriter.StartFragment(fragmentStream, false);  
writer.WriteStartElement("Body");  
writer.WriteString("This is my body");  
writer.WriteEndElement();  
fragmentWriter.EndFragment();  
writer.WriteStartElement("CharsInTheBody");  
writer.WriteValue(fragmentStream.Length);  
writer.WriteEndElement();  
fragmentWriter.WriteFragment(fragmentStream.GetBuffer(), 0, (int)fragmentStream.Length);  
writer.WriteEndElement(); // Root  

備註

寫入在 StartFragment 與 EndFragment 之間擷取的片段，並回呼至 XmlDictionaryWriter 的主要資料流中。 寫入的片段是 count 個位元組，且起始於所提供 offset 中的索引 buffer。 如果提供的片段不是使用這個寫入器執行個體所擷取，則表示此行為是未定義的。
