Not applicable.

Return Value

The contents of the element or an empty string.

Exception typeCondition

XmlException

An error occurred while parsing the XML.

This method returns the content of element, text, white space, significant white space or CDATA nodes.

If positioned on an element, ReadString concatenates all text, significant white space, white space, and CDATA section nodes together and returns the concatenated data as the element content. It stops when any markup is encountered, including comments and processing instructions. This could occur in a mixed content model, or when an element end tag is read.

If positioned on an element text node, ReadString performs the same concatenation from the text node to the element end tag. If the reader is positioned on an attribute text node, ReadString has the same functionality as if the reader were positioned on the element start tag. It returns all the concatenated element text nodes.

If positioned on an attribute, ReadString returns an empty string and moves the reader back to the element that owns the attribute.

If ReadString is called on any other node type, it returns an empty string and the reader is positioned on the next node.

The following example displays the text content of each element.
