Struct Variant

A strongly typed object that readily casts an intrinsic object to the other intrinsic types when possible.

Namespace: FastReport
Assembly: FastReport.Base.dll
Syntax
public struct Variant : IConvertible, IComparable
Remarks

The Variant class is an intrinsic object container structure inspired by Visual Basic 6.0's Variant. The key features of a Variant class include the ability to perform typecasts and arithmetic between types that are not normally considered compatible. For example, if a Variant class contains a string describing a number, such as "1.1", then floating point arithmetic can be performed on it.

Variants are normally considered dangerous because they strip away the effectiveness of type safety, which is the reason why the Visual Basic 6.0 Variant was left out of Visual Basic .NET. However, this implementation restores the Variant structure, both as a proof of concept and as a restoration of the utility and positive merits of the Variant where it can be used responsibly.

Otherwise, if the value on the right is a number, both the Variant and the value on the right are converted to a System.Double, the arithmetic is performed, and the resulting value is converted back to the original type that the Variant previously represented. If the type that the Variant previously represented cannot contain the resulting value--such as if the type is a System.UInt32 and the value is -12--then the type will be converted to a type that can contain the value, such as System.Int32.
