| SetFlag(UInt32, Int32, Boolean) |

| SetFlag(UInt32, Int32, Boolean) |

SetFlag(UInt32, Int32, Boolean)
Sets a bit to a specified value.
public static uint SetFlag (uint value, int n, bool flag);static member SetFlag : uint32 * int * bool -> uint32Public Shared Function SetFlag (value As UInteger, n As Integer, flag As Boolean) As UIntegerParameters
- n
- Int32
The position of the bit to set or clear (in [0, 31] range).
- flag
- Boolean
The value to assign to the target bit.
Returns
An UInt32 value equal to value except for the n-th bit.
Remarks
Just like HasFlag(UInt32, Int32), this method doesn't validate n and does not contain branching instructions, so it's well suited for use in tight loops as well.
Applies to
SetFlag(UInt32, Int32, Boolean)
Sets a bit to a specified value.
public static void SetFlag (ref uint value, int n, bool flag);static member SetFlag : uint32 * int * bool -> unitPublic Shared Sub SetFlag (ByRef value As UInteger, n As Integer, flag As Boolean)Parameters
- n
- Int32
The position of the bit to set or clear (in [0, 31] range).
- flag
- Boolean
The value to assign to the target bit.
Remarks
Just like HasFlag(UInt32, Int32), this method doesn't validate n and does not contain branching instructions, so it's well suited for use in tight loops as well.
Applies to
SetFlag(UInt64, Int32, Boolean)
Sets a bit to a specified value.
public static ulong SetFlag (ulong value, int n, bool flag);static member SetFlag : uint64 * int * bool -> uint64Public Shared Function SetFlag (value As ULong, n As Integer, flag As Boolean) As ULongParameters
- n
- Int32
The position of the bit to set or clear (in [0, 63] range).
- flag
- Boolean
The value to assign to the target bit.
Returns
An UInt64 value equal to value except for the n-th bit.
