XmlReader.ReadElementString Method (String, String)


Checks that the LocalName and NamespaceURI properties of the element found matches the given strings before reading a text-only element. However, we recommend that you use the ReadElementContentAsString(String, String) method instead, because it provides a more straightforward way to handle this operation.

Namespace:   System.Xml
Assembly:  System.Xml (in System.Xml.dll)

Public Overridable Function ReadElementString (
	localname As String,
	ns As String
) As String


Type: System.String

The local name to check.

Type: System.String

The namespace URI to check.

Return Value

Type: System.String

The text contained in the element that was read. An empty string if the element is empty.

Exception Condition

If the next content node is not a start tag; if the element LocalName or NamespaceURI do not match the given arguments; or if the element found does not contain a simple text value.


An XmlReader method was called before a previous asynchronous operation finished. In this case, InvalidOperationException is thrown with the message “An asynchronous operation is already in progress.”

We recommend that you use the ReadElementContentAsString(String, String) method to read a text element.
