CString的用法

用法一：字符串连接

CString gray("Gray");
CString cat("Cat");
CString graycat = gray + cat;

相当于：

char gray[] = "Gray";
char cat[] = "Cat";
char * graycat = malloc(strlen(gray) + strlen(cat) + 1);
strcpy(graycat, gray);
strcat(graycat, cat);

 

用法二：格式化输出，不需要用到printf

CString s;
s.Format(_T("The total is %d"), total);

 

用法三：cstring 转换到int

CString hex = _T("FAB");
CString decimal = _T("4011");
ASSERT(_tcstoul(hex, 0, 16) == _ttoi(decimal));

 

用法四：char* to cstring
