示例1: PeekReference

        public unsafe void PeekReference()
        {
            var table = new byte[]
            {
                0xff, 0xff, 0xff, 0x00, // offset 0
                0xff, 0xff, 0xff, 0x01, // offset 4
                0xff, 0xff, 0xff, 0x1f, // offset 8
                0xff, 0xff, 0xff, 0x2f, // offset 12
                0xff, 0xff, 0xff, 0xff, // offset 16
            };

            fixed (byte* tablePtr = table)
            {
                var block = new MemoryBlock(tablePtr, table.Length);

                Assert.Equal(0x0000ffff, block.PeekReference(0, smallRefSize: true));
                Assert.Equal(0x0000ffff, block.PeekHeapReference(0, smallRefSize: true));
                Assert.Equal(0x0000ffffu, block.PeekReferenceUnchecked(0, smallRefSize: true));

                Assert.Equal(0x00ffffff, block.PeekReference(0, smallRefSize: false));
                Assert.Throws<BadImageFormatException>(() => block.PeekReference(4, smallRefSize: false));
                Assert.Throws<BadImageFormatException>(() => block.PeekReference(16, smallRefSize: false));

                Assert.Equal(0x1fffffff, block.PeekHeapReference(8, smallRefSize: false));
                Assert.Throws<BadImageFormatException>(() => block.PeekHeapReference(12, smallRefSize: false));
                Assert.Throws<BadImageFormatException>(() => block.PeekHeapReference(16, smallRefSize: false));

                Assert.Equal(0x01ffffffu, block.PeekReferenceUnchecked(4, smallRefSize: false));
                Assert.Equal(0x1fffffffu, block.PeekReferenceUnchecked(8, smallRefSize: false));
                Assert.Equal(0x2fffffffu, block.PeekReferenceUnchecked(12, smallRefSize: false));
                Assert.Equal(0xffffffffu, block.PeekReferenceUnchecked(16, smallRefSize: false));
            }
        }
