C# Definition:

enum AnimateWindowFlags : uint
{
    AW_HOR_POSITIVE = 0x00000001,
    AW_HOR_NEGATIVE = 0x00000002,
    AW_VER_POSITIVE = 0x00000004,
    AW_VER_NEGATIVE = 0x00000008,
    AW_CENTER = 0x00000010,
    AW_HIDE = 0x00010000,
    AW_ACTIVATE = 0x00020000,
    AW_SLIDE = 0x00040000,
    AW_BLEND =0x00080000
}

An alternative definition if you do not want to cast the enum-values to int is this:

public sealed class AnimateWindowFlags
{
    public const int AW_HOR_POSITIVE = 0x00000001;
    public const int AW_HOR_NEGATIVE = 0x00000002;
    public const int AW_VER_POSITIVE = 0x00000004;
    public const int AW_VER_NEGATIVE = 0x00000008;
    public const int AW_CENTER = 0x00000010;
    public const int AW_HIDE = 0x00010000;
    public const int AW_ACTIVATE = 0x00020000;
    public const int AW_SLIDE = 0x00040000;
    public const int AW_BLEND = 0x00080000;
}
