XmlReader.ReadContentAsDecimal Method

Definition

Reads the text content at the current position as a Decimal object.

public:
 virtual System::Decimal ReadContentAsDecimal();
public virtual decimal ReadContentAsDecimal ();
abstract member ReadContentAsDecimal : unit -> decimal
override this.ReadContentAsDecimal : unit -> decimal
Public Overridable Function ReadContentAsDecimal () As Decimal

Returns

The text content at the current position as a Decimal object.

Exceptions

The attempted cast is not valid.

The string format is not valid.

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:decimal, the reader returns an unboxed Decimal object. If the content is not typed xsd:decimal, the reader attempts to convert it to a Decimal object 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.
