拆分Int64long 到HighPartLowPart类型

今天研究C#调用API，需要把long类型拆分成LowPart和HighPart两部分，所以写了一个方法，来转换这两种类型。  1 using  System;  2  3 namespace  Skyfei  4 { 5    public struct LargeInteger 6    { 7        Int32 _LowPart; 8        Int32 _HighPart; 9        public Int32 LowPart10        {11            get12            {13                return _LowPart;14            }15            set 16            {17                _LowPart = value;18            }19        }20    21        public Int32 HighPart22        {23            get24            {25                return _HighPart;26            }27            set 28            {29                _HighPart = value;30            }31        }32    }33    /**//// <summary>34    /// LargeInteger 的摘要说明。35    /// </summary>36    public class LInteger37    {38        39        public LInteger()40        {41            //42            // TODO: 在此处添加构造函数逻辑43            //44        }4546        public static long GetLongValue(LargeInteger largeInteger)47        {            48            return (long)(((ulong)largeInteger.HighPart << 32) + (uint)largeInteger.LowPart);49        }5051        public static LargeInteger GetLargeIntegerValue(long longNumber)52        {        53            LargeInteger t = new LargeInteger();54            t.LowPart = (Int32) longNumber;55            t.HighPart = (Int32) (longNumber >> 32);56            return t;57        }58    }59} 60
