FormatException is thrown when the format of an argument in a method invocation does not match the format of the corresponding formal parameter type. For example, if a method specifies a String parameter consisting of two digits with an embedded period, passing a corresponding string argument containing only two digits to that method would cause FormatException to be thrown.

FormatException uses the HRESULT COR_E_FORMAT, which has the value 0x80131537.

For a list of initial property values for an instance of FormatException, see the FormatException constructors.
