c# - 带有c#代码错误的序列化

Question

我正在尝试概括我的一个项目的序列化。

我有如下三个主要类:

test.cs - 一个简单的测试对象

[Serializable()]
    public class test : Attribute {

        public string name = "";
        public int ID = 0;

        public test(string inputName, int inputID) {
            name = inputName;
            ID = inputID;
        }
        public test() {}
    }

Serialization.cs - 我的主要序列化类

public static void SerializeCollection<T>(string path, List<T> collection, Type type) {
            System.Xml.Serialization.XmlSerializer writer = new System.Xml.Serialization.XmlSerializer(type);
            System.IO.StreamWriter file = new System.IO.StreamWriter(path);
            writer.Serialize(file, collection);
}

最后是 Form1.cs - 我的表单类

    private void btnSerialize_Click(object sender, EventArgs e)
    {
        List<test> test = new List<test>();
        test.Add(new test("testing1", 2));
        Serialization.SerializeCollection("Test.txt", test, typeof(test));
    }

当运行并点击按钮时，我得到这个错误:

'An unhandled exception of type 'System.InvalidOperationException' occurred in System.Xml.dll

Additional information: There was an error generating the XML document.'

您使用了不正确的类型进行序列化，您已将 typeof(test) 更改为 typeof(List)

    private static void SerializationTest()
    {
        List<test> test = new List<test>();
        test.Add(new test("testing1", 2));
        SerializeCollection("Test.txt", test, typeof(List<test>));
    }

老实说，在您的情况下，我会避免将类型作为方法的参数:

    private static void SerializationTest()
    {
        const string fileName = "Test.txt";
        var tests = new List<test> {new test("testing1", 2)};            
        SerializeCollection(fileName, tests);
    }

    public static void SerializeCollection<T>(string fullFileName, IEnumerable<T> items)
    {
        var writer = new XmlSerializer(items.GetType());            
        var file = new StreamWriter(fullFileName);
        writer.Serialize(file, items);
    }
