C++Builder常用String方法

C++Bu ilder 常用 String 关于 AnsiSting 的使用大全(1) arrow: Ansistring 转 char 代码: void __fastcall TForm1::Button1Click(TObject *Sender) { AnsiString Test = "哈哈"; char *chr = Test.c_str(); } char 转 Ansistring 代码: #include void __fastcall TForm1::Button1Click(TObject *Sender) { AnsiString str = "Sample"; char chr[MAX_PATH]; strcpy( chr , str.c_str() ); } ansistring 转int 代码: void __fastcall TForm1::Button1Click(TObject *Sender) { AnsiString Test = "123"; int i = StrToInt( Test ); } int 转ansistring 代码: void __fastcall TForm1::Button1Click(TObject *Sender) { int i = 123; AnsiString str = IntToStr( i ); } ansisting 转double 代码: void __fastcall TForm1::Button1Click(TObject *Sender) { AnsiString Test = "123"; long double d = StrToFloat( Test ); } double 转ansistring 代码: void __fastcall TForm1::Button1Click(TObject *Sender) { double d = 123.456; AnsiString str = FloatToStr( d ); } double 转ansistring 并四舍五入 代码: void __fastcall TForm1::Button1Click(TObject *Sender) { long double d = 123.456121212; AnsiString str = FloatToStrF( d , ffFixed ,5 , 4 ); //说明FloatTostrF 里5 代表从第几个数字的后一位开始四舍五入,4 代表取4 位小数。 //执行后得到 str 是 123.4600。:roll: } double 转ansistring 使用类似vb 的format 函数 代码: void __fastcall TForm1::Button1Click(TObject *Sender) { double d = 123.456; AnsiString str = FormatFloat( "000000.00" , d ); } //得到 000123.45，当然你可以使用"# . , ; E+ E- xx"等符号，你自己试试 :wink: ansi 转Tclor 型（从现在开始 AnsiSting 简称 ansi 代码: void __fastcall TForm1::Button1Click(TObject *Sender) { AnsiString Test = "0x00FF8080"; TColor Col = StringToColor( Test ); } Tclor 转ansi 代码: void __fastcall TForm1::Button1Click(TObject *Sender) { TColor Col = 0x00FF8080; AnsiString str = ColorTo...
