我正在使用
这是我的样例 test.xml 文件。
XmlDocument
和 XmlWriter
将 XML 追加到现有文件中,但是我的尝试会抛出一个我不理解的异常:
此文档已经具有“DocumentElement”节点。
//Append to xml file
XmlDocument doc = new XmlDocument();
doc.Load(@"c:\\test.xml");
using (XmlWriter xmlWrite = doc.CreateNavigator().AppendChild())
{
xmlWrite.WriteStartElement("image name=",Name);
xmlWrite.WriteElementString("width", widthValue[1]);
xmlWrite.WriteElementString("Height", heightValue[1]);
xmlWrite.WriteElementString("file-size", FileSizeValue[1]);
xmlWrite.WriteElementString("file-format", FileFormatValue[1]);
xmlWrite.WriteElementString("resolution", ResolutionValue[1]);
xmlWrite.Close();
}
这是我的样例 test.xml 文件。
