实例解析C++/CLI的串行化[VC/C++编程]

串行化可以使对象被转换为某种外部的情势,比方以文件存储的情势供程序利用,或通历程序间的通讯发送到另一个处理历程.转换为外部情势的历程称为"串行化",而逆历程称为"反串行化".

简介

请看例1中的示例,其将多个对象范例的值写入到一个新的磁盘文件中,关闭文件,接着再把这些值重新读取到内存中.

例1:

using namespace System;
using namespace System::IO;
using namespace System::Runtime::Serialization::Formatters::Binary;
int main()
{
　 array<int>^ intArray = {10, 20, 30};
　 array<float,2>^ floatArray = {
　　 {1.2F, 2.4F},
　　 {3.5F, 6.8F},
　　 {8.4F, 9.7F}
　 };
　 DateTime dt = DateTime::Now;
　 Console::WriteLine("dt >{0}<", dt);
　 /*1*/ BinaryFormatter^ formatter = gcnew BinaryFormatter;
　 //将数据串行化到一个文件
　 /*2*/ Stream^ file = File::Open("Sr01.ser", FileMode::Create);
　 /*3a*/ formatter->Serialize(file, "Hello");
　 /*3b*/ formatter->Serialize(file, intArray);
　 /*3c*/ formatter->Serialize(file, floatArray);
　 /*3d*/ formatter->Serialize(file, true);
　 /*3e*/ formatter->Serialize(file, dt);
　 /*3f*/ formatter->Serialize(file, 1000);
　 /*3g*/ formatter->Serialize(file, L'X');
　 /*3h*/ formatter->Serialize(file, 1.23456F);
　 /*4*/ file->Close();
　 //从文件中反串行化数据--即读取数据
　 /*5*/ file = File::Open("Sr01.ser", FileMode::Open);
　 /*6a*/ String^ s = static_cast<String^>(formatter->Deserialize(file));
　 Console::WriteLine("String >{0}<", s);
　 /*6b*/ array<int>^ newIntArray =
　 static_cast<array<int>^>(formatter->Deserialize(file));
　 Console::WriteLine("newIntArray:");
　 for (int i = 0; i < newIntArray->Length; ++i)
　 {
　　 Console::Write(" {0}", newIntArray[i]);
　 }
　 Console::WriteLine();
　 /*6c*/ array<float,2>^ newFloatArray =
　 static_cast<array<float,2>^>(formatter->Deserialize(file));
　 Console::WriteLine("newFloatArray:");
　 for (int i = 0; i < 3; ++i)
　 {
　　 for (int j = 0; j < 2; ++j)
　　 {
　　　 Console::Write(" {0}", newFloatArray[i,j]);
　　 }
　　 Console::WriteLine();
　 }
　 /*6d*/ bool b = static_cast<bool>(formatter->Deserialize(file));
　 Console::WriteLine("bool >{0}<", b);
　 /*6e*/ DateTime newDT = static_cast<DateTime>(formatter->Deserialize(file));
　 Console::WriteLine("newDT >{0}<", newDT);
　 /*6f*/ int v = static_cast<int>(formatter->Deserialize(file));
　 Console::WriteLine("int >{0}<", v);
　 /*6g*/ wchar_t c = static_cast<wchar_t>(formatter->Deserialize(file));
　 Console::WriteLine("wchar_t >{0}<", c);
　 /*6h*/ float f = static_cast<float>(formatter->Deserialize(file));
　 Console::WriteLine("float >{0}<", f);
　 /*7*/ file->Close();
}
