protobuf的使用方式
- 1.手动编写
- 2..proto文件自动生成
1.手动方式
手动编写protobuf序列化的实体类
[ProtoContract]//序列化类
public class Student
{
[ProtoMember(1)]//序列化属性
public string name;
[ProtoMember(2)]
public string sex;
[ProtoMember(3)]
public Address address;
public Student(){}
public Student(string name, string sex, Address address)
{
this.name = name;
this.sex = sex;
this.address = address;
}
}
[ProtoContract]//序列化类
public class Address
{
[ProtoMember(1)]//序列化属性
public string province;
[ProtoMember(2)]
public string city;
[ProtoMember(3)]
public string street;
public Address()
{ }
public Address(string province, string city, string street)
{
this.province = province;
this.city = city;
this.street = street;
}
}
###protobuf序列化和反序列化
public TestProtobuf()
{
//protobuf序列化
Student st = new Student("小明", "男", new Address("河南", "郑州", "东三街"));
MemoryStream ms = new MemoryStream();
Serializer.Serialize<Student>(ms, st);//序列化
string result = Encoding.UTF8.GetString(ms.ToArray());
Console.WriteLine(result);
ms.Close();
//protobuf反序列化
byte[] buffer = Encoding.UTF8.GetBytes(result);
MemoryStream mem = new MemoryStream(buffer);
Student student = Serializer.Deserialize<Student>(mem);//反序列化
mem.Close();
//学生数据解析成功
}2.proto文件方式
1.生成protobuf-net.dll库和protogen.exe工具
- 下载github上的protobuf-net工程地址：[https://github.com/mgravell/protobuf-net]
- 使用vs打开.csproj文件，然后关闭保存，生成.sln文件。
- 使用vs打开.sln文件。
- 使用Nuget下载protobuf-net库。命令 : Install-Package protobuf-net
- 配置管理器为Release，然后生成解决方案。
- 在工程的bin/Release下，找到我们生成的文件，包含一个叫protogen.exe的文件（其他的文件也都有用，不要删除）
2.编译.proto文件
- 编写 percen.proto文件
package information // 定义了package的名字（命名空间）
message Person { //定义message名（类名）
required string name = 1; //必须赋值的字段
optional int32 id = 2; //可以不赋值的字段
repeated string email = 3;//可重复字段做List使用
enum PhoneType { //枚举类型
MOBILE = 0;
HOME = 1;
WORK = 2;
}
message PhoneNumber {
required string number = 1;
optional PhoneType type = 2 [default = HOME];
}
repeated PhoneNumber phone = 4;
}- cmd命令行下编译.proto文件
- 把percen.proto放到protogen.exe的同级目录下。
- cd 到protogen.exe的Release目录下。
- 输入：protogen -i:percen.proto -o:Person.cs 生成percen.cs文件
- 然后把percen.cs拷贝到unity项目中就可以使用了,用法跟手动一样
- percen.cs文件
