帶有C＃代碼錯誤的序列化

Question

我正在嘗試概括我的一個項目的序列化。

我有以下三個主要課程：

test.cs-一個簡單的測試對象

[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-我的主要序列化類

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-我的表單類

    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));
    }

運行並單擊按鈕時，出現此錯誤：

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

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

您使用不正確的類型進行序列化，將typeof（test）更改為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>));
    }

老實說，在這種情況下，我會避免將type作為您的方法的參數：

    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);
    }
