IsValid Method

IsValid(int, int, int)

Check current value is a valid Enum type

Declaration

public static bool IsValid(int enumValue, int minValueOfEnum, int maxValueOfEnum)

Public Shared Function IsValid(enumValue As Integer, minValueOfEnum As Integer, maxValueOfEnum As Integer) As Boolean

Parameters

Type	Name	Description
int	enumValue	An int indivate the value you want to check
int	minValueOfEnum	An int indicate the minimum value of your enum type
int	maxValueOfEnum	An int indicate the maximum value of your enum type

Returns

Type	Description
bool	A bool indicate the check result, if current value is a valid enum type, return true; otherwise false

Remarks

This method is applicable to check a Sequential defined not-flag-style enum type

IsValid(int, int, int, int)

Check current value is a valid Enum type

Declaration

public static bool IsValid(int enumValue, int minValueOfEnum, int maxValueOfEnum, int maxNumberOfBitsOn)

Public Shared Function IsValid(enumValue As Integer, minValueOfEnum As Integer, maxValueOfEnum As Integer, maxNumberOfBitsOn As Integer) As Boolean

Parameters

Type	Name	Description
int	enumValue	An int indivate the value you want to check
int	minValueOfEnum	An int indicate the minimum value of your enum type
int	maxValueOfEnum	An int indicate the maximum value of your enum type
int	maxNumberOfBitsOn	An int indicate the max count of bit for test enum value

Returns

Type	Description
bool	A bool indicate the check result, if current value is a valid enum type, return true; otherwise false

Remarks

This method is applicable to check a Sequential defined flag-style enum type There is a enum value you want to test is 0x5f, in this enum type, the min value is 0x0f, and max value is 0x100, then this method called below can test its validation:

EnumHelper.IsValid(0x5f, 0x0f, 0x100, 8);

In this scenario, the four parameter is 8, because the max value is 0x100(Binary as 100000000), the max bits on value is 0xff (Binary as 11111111), it's the max number of bits on
