问个入门级的问题，Pansichar和String如何转换？？？。。在线等，谢谢。。。。。。。。。 ( 积分: 20 )

如题。。

如题。。

PChar(你的字符串变量)

强制类型转换
pcchar;
s:string;

pc ：＝ PChar(s);
s ：＝ String(pc);

直接赋就是，如下：
var
tmp : PAnsiChar;
str : String;
begin
GetMem( tmp, 5 );
tmp := '1234' + #0;
str := tmp;
Showmessage( str );
end;

同意楼上，不过要注意：
Long string to PChar conversions are not automatic. Some of the differences between strings and PChars can make conversions problematic:

Long strings are reference-counted, while PChars are not.
Assigning to a string copies the data, while a PChar is a pointer to memory.
Long strings are null-terminated and also contain the length of the string, while PChars are simply null-terminated.

Situations in which these differences can cause subtle errors are discussed in this section.

PAnsiChar 指向 null 结束的 AnsiChar 字符串的指针。
PAnsiChar :=pansichar(string);

多人接受答案了。
