如何合并两个TINIfile实例中的条目？(How to merge entries from two TINIfile instances?)

有没有办法将一个TIniFile实例的条目合并到另一个实例？

Is there a way to merge entries from one TIniFile instance to another?

最满意答案

以下是一个可以将两个INI文件合并到一个新的输出INI文件中的过程：

procedure MergeIniFiles(const FromFilename, ToFilename, OutputFilename: String; const Overwrite: Boolean); var IniFrom, IniTo, IniOut: TIniFile; Sec: TStringList; Val: TStringList; X, Y: Integer; S, N, V: String; begin IniFrom:= TIniFile.Create(FromFilename); IniTo:= TIniFile.Create(ToFilename); IniOut:= TIniFile.Create(OutputFilename); Sec:= TStringList.Create; Val:= TStringList.Create; try IniFrom.ReadSections(Sec); for X := 0 to Sec.Count-1 do begin S:= Sec[X]; IniFrom.ReadSection(S, Val); for Y := 0 to Val.Count-1 do begin N:= Val[Y]; V:= IniFrom.ReadString(S, N, ''); IniOut.WriteString(S, N, V); end; end; IniTo.ReadSections(Sec); for X := 0 to Sec.Count-1 do begin S:= Sec[X]; IniTo.ReadSection(S, Val); for Y := 0 to Val.Count-1 do begin N:= Val[Y]; V:= IniTo.ReadString(S, N, ''); if Overwrite then begin IniOut.WriteString(S, N, V); end else begin if not IniOut.ValueExists(S, N) then IniOut.WriteString(S, N, V); end; end; end; finally Val.Free; Sec.Free; IniOut.Free; IniTo.Free; IniFrom.Free; end; end;

Here's a procedure which can merge two INI files together into a new output INI file:

procedure MergeIniFiles(const FromFilename, ToFilename, OutputFilename: String; const Overwrite: Boolean); var IniFrom, IniTo, IniOut: TIniFile; Sec: TStringList; Val: TStringList; X, Y: Integer; S, N, V: String; begin IniFrom:= TIniFile.Create(FromFilename); IniTo:= TIniFile.Create(ToFilename); IniOut:= TIniFile.Create(OutputFilename); Sec:= TStringList.Create; Val:= TStringList.Create; try IniFrom.ReadSections(Sec); for X := 0 to Sec.Count-1 do begin S:= Sec[X]; IniFrom.ReadSection(S, Val); for Y := 0 to Val.Count-1 do begin N:= Val[Y]; V:= IniFrom.ReadString(S, N, ''); IniOut.WriteString(S, N, V); end; end; IniTo.ReadSections(Sec); for X := 0 to Sec.Count-1 do begin S:= Sec[X]; IniTo.ReadSection(S, Val); for Y := 0 to Val.Count-1 do begin N:= Val[Y]; V:= IniTo.ReadString(S, N, ''); if Overwrite then begin IniOut.WriteString(S, N, V); end else begin if not IniOut.ValueExists(S, N) then IniOut.WriteString(S, N, V); end; end; end; finally Val.Free; Sec.Free; IniOut.Free; IniTo.Free; IniFrom.Free; end; end;
