C# NodeInfo.Reset方法代码示例

		// When reading an array (0x03), it requires extraneously
		// complex procedure for XmlReader. First, it reads element,
		// type of operation and length of the items. And this XmlReader
		// has to return Element state. On the next Read(), it proceeds
		// to the value node of the first item of the array, so it
		// reads the value stream. On the next Read(), it proceeds to
		// EndElement, so it should not read anything from stream while
		// it has to move to the node state to EndElement.
