Delphi的StringReplace 字符串替換函數[delphi]

原文來自: 【100腳本網 www.pc100.net】

function StringReplace (const S, OldPattern, NewPattern: string; Flags: TReplaceFlags): string;

rfReplaceAll：全部替換
rfIgnoreCase：忽略大小寫

For Example：

var
    aStr: String;
begin
    aStr := 'This is a book, not a pen!';
    ShowMessage(StringReplace (aStr, 'a', 'two', []));//This is two book, not a pen!只替換了第一個符合的字
    ShowMessage(StringReplace (aStr, 'a', 'two', [rfReplaceAll]));//This is two book, not two pen!替換了所有符合的字
    aStr := 'This is a book, not A pen!';
    ShowMessage(StringReplace (aStr, 'a', 'two', [rfReplaceAll]));//This is two book, not A pen!只替換了符合的字(小寫a)
    ShowMessage(StringReplace (aStr, 'a', 'two', [rfReplaceAll, rfIgnoreCase]));//This is two book, not two pen!不管大小寫替換了所有符合的字
end;
