delphi、C++、C# 数据类型对应
byte:1个字节。
int/Integer:
long:
long long:8字节,64位
shortInt:2字节,16位
LongInt:4字节,32位
Int64:8字节,64位
word:
float:4字节
double:8字节

delphi与C#语法转换
C#功能
byte[] CopyToBig(byte[] bBig, byte[] bSmall) { List<byte> lTemp = new List<byte>(); lTemp.AddRange(bBig); lTemp.AddRange(bSmall); bBig = new byte[lTemp.Count]; lTemp.CopyTo(bBig); return bBig; }
delphi实现
var
aint:integer;
调用函数fun(int *);
fun(&aint);
var TagType:Word
function fun1( x: Integer): Integer;
function fun(var x: Integer): Integer;
function fun2(const x: Integer): Integer;
