c# - 如何将 SAme 类的多个对象序列化为单个文件并在 C# 中反序列化为这些对象

Question

如何将同一类的多个对象序列化为单个文件并在 C# 中反序列化为这些对象

Answer 1

尝试这样的事情:

using (FileStream output = 
    new FileStream("C:\\peoplearray.dat", FileMode.CreateNew))
{
    BinaryFormatter bformatter = new BinaryFormatter();
    bformatter.Serialize(output, 
                         new Person[] {
                             new Person{Firstname="Alex"}
                         });
}
using (FileStream input = 
      new FileStream("C:\\peoplearray.dat", FileMode.Open))
{
    BinaryFormatter bformatter = new BinaryFormatter();
    var results = bformatter.Deserialize(input) as Person[];
    foreach (Person p in results)
    {
        Console.WriteLine(p.Firstname);
    }
}

只要人是[可序列化的]，这就会起作用
