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 "windef.h"
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) 
{
