protosharp不支持列表作爲根對象;您需要將其包裝起來：

public class SomeWrapper 
{ 
    private readonly List<MyClass> items = new List<MyClass>(); 
    [ProtoSharp.Core.Tag(1)] 
    public List<MyClass> Items { get { return items; } } 
} 
... 
var tmp = new SomeWrapper(); 

tmp.Items.AddRange(_forSerialize); 
using (FileStream fs = File.Create("test.ProtoSharp")) 
    ProtoSharp.Core.Serializer.Serialize(fs, tmp); 

using (FileStream fs = File.OpenRead("test.ProtoSharp")) 
    _forSerialize = ProtoSharp.Core.Serializer.Deserialize<SomeWrapper>(fs).Items; 

if (_forSerialize.Count == 4) 
    Console.WriteLine("ProtoSharp serializer work");

這應該與protobuf-net輸出相同（以字節爲單位）。

然而，我會建議（可能不是非常虛心）protobuf-net做同樣的工作，但是已經被大量精煉和優化，遠遠超出了protosharp提供的，另外還支持許多更多的場景。

編輯：有趣的是，它們是不相同輸出; protosharp有2個額外的字節...我會看看我是否可以找出原因......編輯：啊，這只是零默認行爲;不要擔心這一點。有關信息，如果您按如下方式製作MessageType，則兩個基於protobuf的串行器的輸出是100％相同的（如您所希望和預期的那樣）：

[ProtoSharp.Core.Tag(1)] 
[ProtoBuf.ProtoMember(1, IsRequired = true)] 
public int MessageType { get; set; }
