## XPathNavigator::MoveToFirstChild method


当在派生类中被重写时，将 [XPathNavigator](../) 移动到当前节点的第一个子节点。

```cpp
virtual bool System::Xml::XPath::XPathNavigator::MoveToFirstChild()=0
```


### ReturnValue

**true** if the [XPathNavigator](../) is successful moving to the first child node of the current node; otherwise, **false**. If **false**, the position of the [XPathNavigator](../) is unchanged.
