MFC第一周学习(二)CString与其它数据类型转换

CString和char转换

1.char* 转为CString

char* p = "abcd";
CString str = CString(p);

2.CString转换为char*

CStringA temp;
temp = str;
char* p = str.GetBuffer()

CString和int转换

1.CString ->int

	int num;
	CString str;
	str.Format(TEXT("123");
	num = _ttoi(str);

2.int转换为CString

int num = 123;
CString str;
str.Format(TEXT("%d",num));

CString转化为double

1.CString转换为double

double num;
CString str;
str.Format(TEXT"123.4");
num = _ttof(str);

2.double转换为CString

double num = 123.4;
CString str;
str.Format(TEXT("%lf"),num);
