序列化詞典<字符串，對象>

Question

我有一個簡單的類是這樣的：

class Beam 
{ 
    public string Name { get; set; } 
    public double Width { get; set; } 
    public double Height { get; set; } 
} 

而且我在Dictionary使用它作爲一個值：

var addresses = new Dictionary<string, Beam> 
{ 
    {"Beam1", new Beam{Name = "B1", Width = 10, Height = 10}}, 
    {"Beam2", new Beam{Name = "B2", Width = 5, Height = 5}} 
}; 

我怎樣才能Serialize這Dictionary？我能做到這一點時，Dictionary是象下面這樣：

Dictionary<string, string> 

但是，當我使用的是Object作爲它的價值我得到一個例外。

更新

var fs = new FileStream("DataFile.dat", FileMode.Create); 

// Construct a BinaryFormatter and use it to serialize the data to the stream. 
var formatter = new BinaryFormatter(); 
try 
{ 
    formatter.Serialize(fs, addresses); 
} 
catch (SerializationException e) 
{ 
    Console.WriteLine("Failed to serialize. Reason: " + e.Message); 
    throw; 
} 
finally 
{ 
    fs.Close(); 
} 

Answer 1

您應該添加Serializable屬性的類Beam：

[Serializable] 
class Beam 
{ 
    public string Name { get; set; } 
    public double Width { get; set; } 
    public double Height { get; set; } 
} 

Answer 2

您需要標記梁類爲可序列化

[Serializable] 
class Beam 
{ ... }
