进入D7,在默认的新建工程中增加一过程Test(m: Array of const); procedure TForm1.test(m: array of const); var i, zero: Integer; s, t: String; c: Char; const sBoolean: Array [Boolean] of string = ('False', 'True'); begin s := ''; for i := 0 to High(m) do with m[i] ...

Delphi中arrayofconst应⽤ Delphi的Format函数⼤家都⽤得很多,第⼆个参数⽤着确实很⽅便。最近在数据库开发应⽤中需要⾃⼰创建⼀个带array of const参数的函数,对于常⽤的类型String,Integer,Pointer处理都没什么问题,但当⽤到Widestring类型时却出错,摸索了⼀上午,感觉获益良多。现在将问题...
function MakeStr(const Args: array of const): string; const BoolChars: array[boolean] of char = ('F', 'T'); var i: integer; begin result := ''; for i := 0 to High(Args) do with Args[i] do case VType of vtInteger: result := result + IntToStr(VInteger); ...
1、如果是静态数组,定义的时候必须指定长度,如:var array: array[0..2] of string = ("hello","world","yes");(注意,局部变量不能初始化)。2、如果是动态数组,则:var array: array of string;i: integer;begin SetLength(array, len); //len是运行时动态指定的。//然后遍历数组...
procedure TForm1.ProcArray(const Value: array of string); var i:Integer; begin for i:=Low(Value) to High(Value) do OrigNum:=OrigNum+Value[i];//调用后为'Hello abc dbd' lblReturn.Caption:=OrigNum; end; 调用: OrigNum:='Hello'; ...
array of const Delphi的Format函数大家都用得很多,第二个参数用着确实很方便。最近在数据库开发应用中需要自己创建一个带array of const参数的函数,对于常用的类型String,Integer,Pointer处理都没什么问题,但当用到Widestring类型时却出错,摸索了一上午,感觉获益良多。现在将问题、解决问题的思路、分析方法等一一道来...
