std::stringstream stream; char result[8] ; string s("8888"); stream << s; //向stream中插入8888 stream >> result; //抽取stream中的值到result 1. 2. 3. 4. 5. 利用模板转换 还可以利用模板,进行同一类转换: template<class T> void to_string(string& result,const T& t) { ostringstream ...
publicstaticStream StringToStream(stringstr) { byte[] strBytes = Encoding.UTF8.GetBytes(str); returnnewMemoryStream(strBytes); }
例如,需要将各种数字值,如int、long、double等等转换成字符串,要使用以一个string类型和一个任意值t为参数的to_string()函数。to_string()函数将t转换为字符串并写入result中。使用str()成员函数来获取流内部缓冲的一份拷贝: template<class T> void to_string(string & result,const T& t) { ostringstream o...

最后,通过以下方式初始化一个final String。 StringFinal_String=newString(Output_Stream.toByteArray()); 让我们通过以下代码来学习它。 packagecom.jiyik;importjava.io.*;classExample2{publicstaticvoidmain(String[] args)throwsIOException{ByteArrayOutputStreamOutput_Stream=newByteArrayOutputStream();StringDemo...
