错误C2355:"this":只能在非静态成员函数或非静态数据成员初始化器中引用 [英] error C2355: 'this' : can only be referenced inside non-static member functions or non-static data member initializers
问题描述
我在编译代码时遇到一些问题.它说,
I'm having some problems compiling my code. It says,
错误C2355:"this":只能在非静态成员中引用 函数或非静态数据成员初始化器
error C2355: 'this' : can only be referenced inside non-static member functions or non-static data member initializers
出现错误的部分代码
double getR() {
return this->r;
}
double getG() {
return this->g;
}
double getB2() {
return this->b2;
}
也在这里
rez.r = this->r / 2 + a.getR() / 2;
rez.g = this->g / 2 + a.getG() / 2;
rez.b2 = this->b2 / 2 + a.getB2() / 2;
有什么想法吗?
已修复.
现在这部分代码有相同的错误...
Same error on this part of code now...
rez.r = this->r / 2 + a.getR() / 2;
rez.g = this->g / 2 + a.getG() / 2;
rez.b2 = this->b2 / 2 + a.getB2() / 2;
它也说
错误C2227:'-> r'的左侧必须指向类/结构/联合/泛型类型
error C2227: left of '->r' must point to class/struct/union/generic type
推荐答案
您需要将类范围添加到您的方法中,例如,如果您的类名为YourClass
,则您的函数应为
You need to add the class scope to your methods, for example if your class is named YourClass
then your function would be
double YourClass::getR() {
return this->r;
}
否则,getR
是自由功能,因此没有this
可以进行操作.其他方法也一样.
Otherwise getR
is a free function, and therefore has no this
to operate on. The same goes for your other methods.
