RemarksDepending on supplied constructor arguments, one of the following holds:
-
if there is no minimum specified, then the error message is identified by StringLengthMaxErrorMessage
and can use additional argument
Field Value
Type:
{4} to refer to the maximum value specified, -
or if there is maximum is equal to MaxValue, then the error message is identified by StringLengthMinErrorMessage
and can use additional argument
Field Value
Type:
{4} to refer to the minimum value specified, -
otherwise, the error message is identified by StringLengthRangeErrorMessage
and can use additional arguments
