示例1: ValidatePeekReferenceSize

        public unsafe void ValidatePeekReferenceSize()
        {
            byte[] buffer = new byte[8] { 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0x01 };
            fixed (byte* bufferPtr = buffer)
            {
                var block = new MemoryBlock(bufferPtr, buffer.Length);

                // small ref size always fits in 16 bits
                Assert.Equal(0xFFFF, block.PeekReference(0, smallRefSize: true));
                Assert.Equal(0xFFFF, block.PeekReference(4, smallRefSize: true));
                Assert.Equal(0xFFFFU, block.PeekTaggedReference(0, smallRefSize: true));
                Assert.Equal(0xFFFFU, block.PeekTaggedReference(4, smallRefSize: true));
                Assert.Equal(0x01FFU, block.PeekTaggedReference(6, smallRefSize: true));

                // large ref size throws on > RIDMask when tagged variant is not used.
                Assert.Throws<BadImageFormatException>(() => block.PeekReference(0, smallRefSize: false));
                Assert.Throws<BadImageFormatException>(() => block.PeekReference(4, smallRefSize: false));

                // large ref size does not throw when Tagged variant is used.
                Assert.Equal(0xFFFFFFFFU, block.PeekTaggedReference(0, smallRefSize: false));
                Assert.Equal(0x01FFFFFFU, block.PeekTaggedReference(4, smallRefSize: false));

                // bounds check applies in all cases
                Assert.Throws<BadImageFormatException>(() => block.PeekReference(7, smallRefSize: true));
                Assert.Throws<BadImageFormatException>(() => block.PeekReference(5, smallRefSize: false));
            }
        }
