将TBytes(UTF-16)转换为字符串的最佳方式是什么? [英] What is the best way to convert TBytes (UTF-16) to a string?
问题描述
由于TBytes不存储一个空终止符,所以以下只有当数组恰好在与它相邻的内存中有#0时才会工作。
MyString:= string(myBytes);
如果没有,字符串结果将在最后有随机数据(它也可能导致读取违反取决于在内存中遇到#0的时间)。
如果我使用ToBytes函数,它返回't'#0'e'#0 '#0't'#0,这不是我想要的。
我最后使用
TEncoding.Unicode.GetString(MyByteArray);
What is the best way to convert an array of bytes declared as TBytes to a unicode string in Delphi 2009? In my particular case, the TBytes array has UTF-16 encoded data already (2 bytes for each char).
Since TBytes doesn't store a null terminator, the following will only work if the array happens to have #0 in the memory adjacent to it.
MyString := string( myBytes );
If not, the string result will have random data at the end (it could also probably cause a read violation depending on how long it took to encounter a #0 in memory).
If I use the ToBytes function, it returns 't'#0'e'#0's'#0't'#0, which is not what I want.
I ended up using
TEncoding.Unicode.GetString( MyByteArray );
