2.CString转换到char*

多字节模式下:

CString -->char *

 CString str1 ="";
 char *t1 =str1.GetBuffer(str1.GetLength());
 str1.ReleaseBuffer();  

char * -->CString

 char *str ="aaaa"  

 CString str1(str);  

CString -->int

 CString str1 ="";
 int i =atoi(str1);  

int -->CString

 int i =;
 CString str;
 str.Format("%d",i); 

Unicode编码模式下

CString -->char *

 CString str1 =_T("");
 int len =WideCharToMultiByte(CP_ACP,,str1,-,NULL,,NULL,NULL);
 char *ptxtTemp =new char[len +];
 WideCharToMultiByte(CP_ACP,,str1,-,ptxtTemp,len,NULL,NULL );  

 //...
 delete[] ptxtTemp;  

char * -->CString

 char *p ="test";
 CString str(p);
 //...  

CString -->int

CString str2 =_T("");
int i;
swscanf(str2,_T("%d"),&i);  

int -->CString

 int j =;
 CString str3;
 str3.Format(_T("%d"),j);
