错误 1 error C2440: “”: 无法从“std::ostringstream”转换为“illegalPar

[赵小咖]

template<class T>
arrayList<T>::arrayList(int initialCapicity)
{
if (initialCapicity < 1)
{
ostringstream s;
s << "initial capicity=" << initialCapicity << "must be > 0";
throw illegalParameterValue(s.str());
}
arrayLength = initialCapicity;
element = new T[arrayLength];
listSize = 0;
}
出现如下错误：
错误 1 error C2440: “<function-style-cast>”: 无法从“std::ostringstream”转换为“illegalParameterValue”
请各位大神帮忙看看怎么改

没实现std::ostringstream到illegalParameterValue的转换呗

问题已经解决了，谢谢！ 加了#include“sstream”
