C# ulong to byte array

WebSep 29, 2024 · The native-sized integer types are represented internally as the .NET types System.IntPtr and System.UIntPtr. Starting in C# 11, the nint and nuint types are aliases for the underlying types. The default value of each integral type is zero, 0. Each of the integral types has MinValue and MaxValue properties that provide the minimum and maximum ... WebMay 27, 2016 · A fairly easy way to make this faster is to obtain a ulong* to the array and compare 8 byte chunks at a time with 0xFFFFFFFFFFFFFFFFUL. You will likely need to handle misalignment at the start and end of the array by comparing byte-wise there. You can then unroll the loop maybe 4 times to reduce loop overhead to almost nothing.
