定義
重要
部分資訊涉及發行前產品，在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊，不做任何明確或隱含的瑕疵擔保。
將 XML 片段寫入寫入者底層串流。
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 -> unitPublic Sub WriteFragment (buffer As Byte(), offset As Integer, count As Integer)參數
- buffer
- Byte[]
要寫入的緩衝區。
- offset
- Int32
寫入 buffer的起始位置。
- count
- Int32
要寫入 buffer.
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 和 StartFragment 之間EndFragment擷取的片段，並呼叫回 XmlDictionaryWriter 的主流。 所寫入的片段是count從所提供 offset索引開始buffer的位元組。 若提供片段未被此寫入實例捕捉，則行為為未定義。
