访问作为泛型类型传递的类属性

我有两个类，它们被传递给序列化方法，我想在序列化方法中访问这些类的两个属性。问题是序列化方法参数作为泛型类型传递，我不知道在这种情况下如何访问传递的类的属性。下面的例子。

    public class MyClass1 
    {

            public string MyProperty1 { get; set; }

            //These properties are shared in both classes
            public bool Result { get; set; }
            public string EngineErrorMessage { get; set; }

    }
    public class MyClass2 
    {

            public string MyProperty2 { get; set; }

            //These properties are shared in both classes
            public bool Result { get; set; }
            public string EngineErrorMessage { get; set; }

    }


//The method is used to serialize classes above, classes are passed as generic types
    public void Serialization<T>(ref T engine)
            {
                try
                {
                 //Do some work with passed class
                 }
                catch (Exception e)
                {

                   //If Exception occurs I would like to write values to passed class properties, how to do that?
                   Result = false;
                   EngineErrorMessage = e.Message;
                }
    }

完整方法代码

     public void Submit<T>(ref T engine)
        {
            try
            {

                var workingDir = Path.Combine(Settings.FileStoragePath, Helpers.GetRandomInt(9).ToString());



                Directory.CreateDirectory(workingDir);
                var inputFile = Path.Combine(workingDir, Settings.InFileName);
                var outputFile = Path.Combine(workingDir, Settings.OutFileName);
                var deleteFile = Path.Combine(workingDir, Settings.DelFileName);

                try
                {



                    using (var stream = new FileStream(inputFile, FileMode.Create, FileAccess.Write, FileShare.None))
                    {
                        Serializer.Serialize(stream, engine);
                    }


                    CheckStatus(outputFile);


                    using (var stream = new FileStream(outputFile, FileMode.Open, FileAccess.Read, FileShare.None))
                    {
                        engine = Serializer.Deserialize<T>(stream);                        
                    }


                }
                finally
                {
                    File.Create(deleteFile).Dispose();
                }
            }
            catch (Exception e)
            {
                //ToDo: Not implemented yet.
/*               Result = false;
               ErrorMessage = e.Message;*/
            }
        }

声明一个包含属性的接口Result and EngineErrorMessage。现在你有两个选择：

1. 向序列化类型参数添加约束，以便只有从上述接口派生的类型才能序列化，或者
2. 在你的 catch 块中尝试投射engine到上面提到的界面。如果转换成功，则写入属性值，否则不执行任何操作。

Sample:

public interface ISerializationErrorWriter
{
    bool Result { set; get; }
    string EngineErrorMessage { set; get; }
}

public class MyClass1 : ISerializationErrorWriter
{
    public string MyProperty1 { get; set; }

    public bool Result { get; set; }
    public string EngineErrorMessage { get; set; }
}

public class MyClass2 : ISerializationErrorWriter
{
    public string MyProperty2 { get; set; }

    public bool Result { get; set; }
    public string EngineErrorMessage { get; set; }
}

// Option 1:
public void Serialization_1<T>(ref T engine) where T : ISerializationErrorWriter
{
    try
    {
        //Do some work with passed class
    }
    catch (Exception e)
    {
        engine.Result = false;
        engine.EngineErrorMessage = e.Message;
    }
}

// Option 2:
public void Serialization_2<T>(ref T engine)
{
    try
    {
        //Do some work with passed class
    }
    catch (Exception e)
    {
        var serializationErrorWriter = engine as ISerializationErrorWriter;
        if(serializationErrorWriter != null)
        {
            serializationErrorWriter.Result = false;
            serializationErrorWriter.EngineErrorMessage = e.Message;
        }
    }
}
