如何將2個32位無符號整數合並為64位整數

Question

可以說我有2個無符號整數
首先值為&H0D345B40
值&H9AF34A32第二

如何生成值為&H324AF39A405B340D的無符號64位整數

這是我嘗試過的

dim crypt1 as uint32 = &H0D345B40
dim crypt2 as uint32 = &H9AF34A32

Dim output As UInt64 = (CType(CType(crypt1, UInt64), Long) Or (crypt2 << 32))

the output is &H000000009FF75B72

Answer 1

解決了一個糟糕的方法，但無論如何都還不錯

    dim output() as uint64
    Dim bytes() As UInteger = {crypt1, crypt2}

    Buffer.BlockCopy(bytes, 0, output, 0, 8)
