我按照以下答案here中的说明构建了一些类,以便能够序列化通用对象列表;例如KeyValuePair和KeyValuePair的实例。
不幸的是,GetProto()方法生成的.proto文件似乎不会生成可以为C ++正确解析的文件。为数组生成的子类型消息后缀为" []"。 protoc.exe在" []"上窒息在编译C ++时。
由于protobuf的消息名称似乎是任意的(也就是说,它们实际上并未包含在数据流中),因此可以告诉protobuf-net使用" _Array"而不是" []"什么时候命名子类型?或者我是否应该采取其他途径,以便生成的.proto文件可以被C ++应用程序使用?
谢谢,
以下是相关代码和生成的原型文件。
基类是:
[DataContract]
[ProtoInclude(101, typeof(KeyValuePairResponse<string>))]
[ProtoInclude(102, typeof(KeyValuePairResponse<int>))]
[ProtoInclude(103, typeof(KeyValuePairResponse<double>))]
[ProtoInclude(111, typeof(KeyValuePairResponse<string[]>))]
[ProtoInclude(112, typeof(KeyValuePairResponse<int[]>))]
[ProtoInclude(113, typeof(KeyValuePairResponse<double[]>))]
public abstract class KeyValuePairResponse
{
protected KeyValuePairResponse() { }
[DataMember(Order = 1, IsRequired = true)]
public string Key { get; set; }
public object Value
{
get
{
return this.ValueImplementation;
}
set
{
this.ValueImplementation = value;
}
}
protected abstract object ValueImplementation { get; set; }
public static KeyValuePairResponse<T> Create<T>(string key, T value)
{
return new KeyValuePairResponse<T>(key, value);
}
}
,泛型类是:
[DataContract]
public sealed class KeyValuePairResponse<T> : KeyValuePairResponse
{
public KeyValuePairResponse()
{
}
public KeyValuePairResponse(string key, T value)
{
this.Key = key;
this.Value = value;
}
[DataMember(Order = 2, IsRequired = true)]
public new T Value { get; set; }
protected override object ValueImplementation
{
get
{
return this.Value;
}
set
{
this.Value = (T)value;
}
}
}
GetProto<KeyValuePairResponse>()
创建的.proto文件如下所示:
message KeyValuePairResponse {
required string Key = 1;
// the following represent sub-types; at most 1 should have a value
optional KeyValuePairResponse_String KeyValuePairResponse_String = 101;
optional KeyValuePairResponse_Int32 KeyValuePairResponse_Int32 = 102;
optional KeyValuePairResponse_Double KeyValuePairResponse_Double = 103;
optional KeyValuePairResponse_String[] KeyValuePairResponse_String[] = 111;
optional KeyValuePairResponse_Int32[] KeyValuePairResponse_Int32[] = 112;
optional KeyValuePairResponse_Double[] KeyValuePairResponse_Double[] = 113;
}
message KeyValuePairResponse_Double {
required double Value = 2 [default = 0];
}
message KeyValuePairResponse_Double[] {
repeated double Value = 2;
}
message KeyValuePairResponse_Int32 {
required int32 Value = 2 [default = 0];
}
message KeyValuePairResponse_Int32[] {
repeated int32 Value = 2;
}
message KeyValuePairResponse_String {
required string Value = 2;
}
message KeyValuePairResponse_String[] {
repeated string Value = 2;
}

这只是GetProto中的一个错误。我建议将它记录在github protobuf-net列表中,如果你喜欢冒险,甚至可以提交拉取请求。
