When converting to Boolean from an attribute or element, allowed values are "0", "1", and any string that produces "true" or "false" after trimming and conversion to lower case.

The following example creates an attribute with Boolean content. It then retrieves the value by casting to Nullable<'T> of Boolean.

No code example is currently available or this language may not be supported.

This example produces the following output:

Nullable boolean: BoolValue1=True
Nullable boolean: BoolValue2=False
