错误解决 error CS0117: ‘Buffer‘ does not contain a definition for ‘BlockCopy‘

Unity 2022.3.9f1 导入 Runtime OBJ Importer 后出现：
error CS0117: ‘Buffer’ does not contain a definition for ‘BlockCopy’

解决办法：

源代码：

int DDS_HEADER_SIZE = 128;
byte[] dxtBytes = new byte[ddsBytes.Length - DDS_HEADER_SIZE];
Buffer.BlockCopy(ddsBytes, DDS_HEADER_SIZE, dxtBytes, 0, ddsBytes.Length - DDS_HEADER_SIZE);

改成：

int DDS_HEADER_SIZE = 128;
byte[] dxtBytes = new byte[ddsBytes.Length - DDS_HEADER_SIZE];
Array.Copy(ddsBytes, DDS_HEADER_SIZE, dxtBytes, 0, ddsBytes.Length - DDS_HEADER_SIZE);

几乎所有类似的问题，都可以把Buffer.BlockCopy()改为Array.Copy()来解决。
