## XmlReader::ReadToDescendant(String, String) method


将 [XmlReader](../) 前进到具有指定本地名称和命名空间 URI 的下一个后代元素。

```cpp
virtual bool System::Xml::XmlReader::ReadToDescendant(String localName, String namespaceURI)
```


| Parameter | Type | 描述 |
| --- | --- | --- |
| localName | 字符串 | 您希望移动到的元素的本地名称。 |
| namespaceURI | 字符串 | 您希望移动到的元素的命名空间 URI。 |

### ReturnValue

**true** if a matching descendant element is found; otherwise **false**. If a matching child element is not found, the [XmlReader](../) is positioned on the end tag ([XmlReader::get_NodeType](../get_nodetype/) value is [XmlNodeType::EndElement](../../xmlnodetype/)) of the element. If the [XmlReader](../) is not positioned on an element when [XmlReader::ReadToDescendant(String,String)](./) was called, this method returns **false** and the position of the [XmlReader](../) is not changed.
