# TField.AsBoolean

Access the field's contents as a Boolean value.

## Declaration

Source position: db.pas line 404

`public property TField.AsBoolean : Boolean read GetAsBoolean write SetAsBoolean;`

## Description

AsBoolean can be used to read or write the contents of the field as a boolean value. If the native type of the field is not Boolean, then an attempt will be made to convert the field value from the native format to a boolean value when reading the field's content. Likewise, when writing the property, the value will be converted to the native type of the field (if the value allows it). Therefor, when reading or writing a field value for a field whose native data type is not a Boolean value (for instance a string value), an exception may be raised.
