Delphi 分割字符串

delphi有个extrastring的函数用来分割字符串

Unit Classes

Syntax

Description < by specified null-terminated the of fill to ExtractStrings>

< is character quote if quoted in appear can characters that (Note quote. end final until inside when ignored are Separators separators. as treated always double) or (single and characters, newline returns, Carriage substrings. separating delimiters, used set>

< beginning at occur they Content parsing be>

< into parse> 如果我想分割以下字符串：
ABC|... DEF|#### GHI|"中华网URL|# www.china.com"

希望得到下面四个字符串：
1、ABC
2、DEF
3、GHI
4、中华网URL|# www.china.com

那么可以用下面的代码：

uses
Classes;
var
ASource: PChar;
AStr: String;
ACount: Integer;
AStrings: TStringList;
begin
ASource := 'ABC|... DEF|#### GHI|"中华网URL|# www.china.com"';
AStrings := TStringList.Create;
try
ACount := ExtractStrings(['|'], [' ','#','.'], ASource, AStrings);
{do any further processing}
//for AStr in AStrings do
// Writeln(AStr);
finally
AStrings.Free;
end;

Readln;
end.

< already strings any so ExtractStrings, cleared not The added. all which>< Strings added number returns>

ExtractStrings does not add empty strings to the list.

[E文看着比较累，还是中文一下吧]:

WhiteSpace 参数指定每个子串开头被忽略的字符s。
Content 参数就是被分割的“源”串了。
Strings 参数用于接收分割后的各个子串。它的原有内容不会被清空。别忘了对Strings进行Create哦。
另外，EctractStrings不会把空串放入Strings中去。

举个例子吧：

ExtractStrings(Separators: TSysCharSet; WhiteSpace: TSysCharSet; Content: PAnsiChar; Strings: TStrings): Integer;

procedure TForm1.Button1Click(Sender: TObject);
var
tempStr: String;
DelimiterPos: Integer;
begin
tempStr:= 'Delphi 电脑网络 其他编程语言';
DelimiterPos:= Pos(' ', tempStr); //这句就知道长度了
tempStr:= Copy(tempStr, 0, DelimiterPos);
ShowMessage(tempStr);
end;

文字处理我的强项
var
tmpStr, tmpPosStr: string;
tmpInt: integer;
......
begin
......
tmpStr:= 'Delphi电脑网络 其他编程语言';//字串
tmpPosStr:= ' ';//分割符
tmpInt:= Pos(tmpPosStr, tmpStr);//分割符位置
if tmpInt>0 then
begin
Edit1.Text := copy(tmpStr，1，tmpInt）;
Edit1.Text := copy(tmpStr，tmpInt，Length(tmpStr)）;
end;
......
end;

随手写的,没有编译过,如有手误或者其它错误包含一下

这是一个分割符,分成两个字串的例子,你可以自己改改改成其它例子

edit1.text :=copy('Delphi电脑网络 其他编程语言'，1，6）;
