delphi - Delphi 7 中 For..in 循环的替代方案？

Question

编译此代码时，我在 Delphi 7 for in 循环中遇到错误 Link

procedure GetProcessorInfo;
Var
  SMBios             : TSMBios;
  LProcessorInfo     : TProcessorInformation;
  LSRAMTypes         : TCacheSRAMTypes;
begin
  SMBios:=TSMBios.Create;
  try
      WriteLn('Processor Information');
      if SMBios.HasProcessorInfo then
      for LProcessorInfo in SMBios.ProcessorInfo do // <-- Error here
      begin
        ...
      end;
  ...
end;

错误消息:

[Error] Project1.dpr(52): Operator not applicable to this operand type

有什么替代方法吗？或者我该如何解决它？

Delphi 7不支持for .. in，所以你必须自己迭代TSMBios.ProcessorInfo数组

procedure GetProcessorInfo;
Var
  SMBios             : TSMBios;
  LProcessorInfo     : TProcessorInformation;
  LSRAMTypes         : TCacheSRAMTypes;
  LIdx : Integer; // add this
begin
  SMBios:=TSMBios.Create;
  try
    WriteLn('Processor Information');
    if SMBios.HasProcessorInfo then
      // for LProcessorInfo in SMBios.ProcessorInfo do
      for LIdx := Low( SMBios.ProcessorInfo ) to High( SMBios.ProcessorInfo ) do
      begin
        LProcessorInfo := SMBios.ProcessorInfo[LIdx];
        ...
      end;
  ...
end;
