Constructors
Variable(double, bool)
Initializes a new instance of the
public Variable(double dValue, bool bRoundUp)
Parameters
dValue double

bRoundUp bool
Determines whether is value without limiting the precision.
Variable(double)
Initializes a new instance of the
public Variable(double dValue)
Parameters
dValue double
The value of Variable(double type). This value will be rounded.

Methods
Clone()
public virtual object Clone()
Returns
object
ConvertToValue(string)
Convert to value.
protected override bool ConvertToValue(string strValue)
Parameters
strValue string
The string.
Returns
bool
GetFullName()
public virtual string GetFullName()
Returns
string
GetNumericValue()
Get numeric value.
protected override double GetNumericValue()
Returns

GetSchema()
This method is reserved and should not be used. When implementing the IXmlSerializable interface, you should return nullNothingnullptra null reference (Nothing in Visual Basic) (Nothing in Visual Basic) from this method, and instead, if specifying a custom schema is required, apply the XmlSchemaProviderAttribute to the class.
public virtual XmlSchema GetSchema()
Returns
XmlSchema
GetValue(string)
public static double GetValue(string strValue)
Parameters
strValue string
Returns
double

protected override void LinkRequestDestroying(object obNotifier, LinkEventArgs arg)
Parameters
obNotifier object
arg LinkEventArgs
The destroy event information.
LinkRequestUpdate(object, LinkEventArgs)

ParseToValue(char*)
Parse to value.
protected override void ParseToValue(char* wstrValue)
Parameters
wstrValue char*
The string.
ReadXml(XmlReader)
Generates an object from its XML representation.
public virtual void ReadXml(XmlReader reader)
Parameters

The XmlReader stream from which the object is deserialized.
SetDefaultString(ref string)
Set default string.
