Açıklamalar
ToUInt32Yöntemi, bayt dizininden startIndex
startIndex
+ 3 UInt32 değerine dönüştürür.The ToUInt32 method converts the bytes from index startIndex
to startIndex
+ 3 to a UInt32 value. Dizideki baytların sırası, bilgisayar sisteminin mimarisinin bitiğünü yansıtmalıdır; daha fazla bilgi için, sınıf konusunun açıklamalar bölümüne bakın BitConverter .The order of bytes in the array must reflect the endianness of the computer system's architecture; for more information, see the Remarks section of the BitConverter class topic.
