XmlReader.ReadContentAsInt XmlReader.ReadContentAsInt XmlReader.ReadContentAsInt XmlReader.ReadContentAsInt Method

Definition

Reads the text content at the current position as a 32-bit signed integer.

public:
 virtual int ReadContentAsInt();
public virtual int ReadContentAsInt ();
abstract member ReadContentAsInt : unit -> int
override this.ReadContentAsInt : unit -> int
Public Overridable Function ReadContentAsInt () As Integer

Returns

The text content as a 32-bit signed integer.

Exceptions

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."

Remarks

This method concatenates text, white space, significant white space, and CDATA sections, and skips any comments or processing instructions. Entity references are automatically resolved.

If the content is typed xsd:integer, the reader returns an unboxed 32-bit signed integer. If the content is not typed xsd:integer, the reader attempts to convert it to a 32-bit signed integer according to the rules defined by the W3C XML Schema Part 2: Datatypes recommendation.

The following table describes how this method treats each node type.

XmlNodeType Return value Reader behavior

EntityReference

EndEntity
Concatenated content of text, CDATA, white space and significant white space nodes converted to the requested type. Moves to the next start element or end element tag. Entity references are automatically expanded.
Attribute Same as calling XmlConvert.ToXxx on the attribute value. The reader remains in the current position.
Comment

ProcessingInstruction
Ignores the processing instruction (PI) or comment and reads the concatenated text content that follows the PI or comment. Moves to the next start element or end element tag. Entity references are automatically expanded.
EndElement An empty string. The reader remains in the current position.
