XMLSerialize 异常 [英] XMLSerialize Exception

问题描述

我正在序列化一个类，但出现以下异常:

I am serializing a class and I get the following exception:

您必须在 System.Configuration.SettingsPropertyCollection 上实现默认访问器，因为它继承自 ICollection.

You must implement a default accessor on System.Configuration.SettingsPropertyCollection because it inherits from ICollection.

当以下行被执行时:

XmlSerializer xs = new XmlSerializer(typeof(CustomConfiguration));

有什么帮助吗?

public class CustomConfiguration : ConfigurationObjectBase 
{ 

         public CustomConfiguration () { //DO NOTHING. } 

         [User] 
         public uint Version 
         { get { return ((uint)(this["Version"])); } 
           set { this["Version"] = value; } 
}

} 

ConfigurationObjectBase 派生自 System.configuration.ApplicationSettingsBase.

推荐答案

"default accessor" 是根据它的索引.例如:

"default accessor" is the special property that returns an object of the collection based on its index. for example:

[Serializable()]
public class IntList : ICollection {

    // Default Accessor Implementation
    public int this[int index] {
        get {

            return 0;
        }
        set { /* Do Nothing */ }
    }
}

因此无法在现有的第三方类中实现.对 ApplicationSettings 使用 xml 序列化是非常糟糕的主意，请使用 Save()、Reload() 和 Reset() 方法，或者使用您自己的不是从 ApplicationSettingsBase CustomConfiguration 类派生的方法.

Therefore unavailable to implement that in existing third-party class. Using xml serializing for ApplicationSettings is very bad idea, use Save(), Reload() and Reset() methods, or use your own not derived from ApplicationSettingsBase CustomConfiguration classes.
