EVC下如何将一个CString类型转换成一个double类型？

[fu_memony]

CString　str;
str=L"111.111";
现在我想把这个CString类型变量的字符串变成double类型
请问我该怎么做？

[lbing7]

CString s="1231.4";
double d = atof(s);

[lbing7]

char tokenstring[] = "15";
float fp;

/* Input various data from tokenstring: */
sscanf( tokenstring, "%f", &fp );

/* Output the data read */
printf( "Real: = %f\n", fp );

输出:
Real: = 15.000000

方法如下：
cstring cs;
unsigned short *num;
double k;
k=wcstod(cs,&num);
就把字符串cs转换成double型k啦
