Reads the text content at the current position as a double-precision floating-point number.
Syntax
Returns
The text content as a double-precision floating-point number.
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:double, the reader returns a double-precision floating-point number. If the content is not typed xsd:double, the reader attempts to convert it to a double-precision floating-point number according to the rules defined by the tp://go.microsoft.com/fwlink/?LinkId=4871 recommendation.
The following table describes how this method treats each node type.
|
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. |
