# TField.AsLargeInt

Access the field's contents as a 64-bit signed integer (longint) value.

## Declaration

Source position: db.pas line 391

`public property TField.AsLargeInt: LargeInt read GetAsLargeInt write SetAsLargeInt;`

## Description

AsLargeInt can be used to read or write the contents of the field as a 64-bit signed integer value (of type Int64). If the native type of the field is not an Int64 value, then an attempt will be made to convert the field value from the native format to an Int64 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 64-bit signed integer-compatible value (string values for instance), an exception may be raised.
