XmlReader.ReadContentAsDecimal Method
Reads the text content at the current position as a Decimal object.
Assembly: System.Xml (in System.Xml.dll)
| Exception | Condition |
|---|---|
| InvalidCastException | The attempted cast is not valid. |
| FormatException | The string format is not valid. |
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.
XmlNodeType | Return value | Reader behavior |
|---|---|---|
Text CDATA Whitespace SignificantWhitespace 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. |
Element XmlDeclaration None Document DocumentType Notation Entity DocumentFragment | An InvalidOperationException is thrown. | Undefined, although typically the reader remains in the current position. |
