C# XML 可序列化集合

Question

我得到了下面的 XML（它只是我遇到問題的大 XML 的一部分），我正在嘗試創建一個 Serializable 類來讀取相同的內容。

<BANKTRANLIST>
  <DTSTART>20051001</DTSTART>
  <DTEND>20051028</DTEND>
  <STMTTRN> <!-- This element can repeat any number of times -->
    <TRNTYPE>CHECK</TRNTYPE>
    <DTPOSTED>20051004</DTPOSTED>
    <TRNAMT>-200.00</TRNAMT>
  </STMTTRN>
  <STMTTRN>
    <TRNTYPE>ATM</TRNTYPE>
    <DTPOSTED>20051020</DTPOSTED>
    <TRNAMT>-300.00</TRNAMT>
  </STMTTRN>
</BANKTRANLIST>

我的 C# 實現

[Serializable]
[XmlRoot("BANKTRANLIST", Namespace = "http://bank.net", IsNullable = false)]
public class BankTransactionList
{
    public BankTransactionList()
    {
        this.StatementTransactions = new List<StatementTransaction>();
    }

    [XmlElement("DTSTART")]
    public string StartDate { get; set; }

    [XmlElement("DTEND")]
    public string EndDate { get; set; }

    [XmlArray("STMTTRN")]
    [XmlArrayItem("STMTTRN")]
    public List<StatementTransaction> StatementTransactions { get; set; }
}


[Serializable]
[XmlRoot("STMTTRN", Namespace = "http://bank.net", IsNullable = false)]
public class StatementTransaction
{
    // TransactionType : ENUM
    [XmlElement("TRNTYPE")]
    public TransactionType TransactionType { get; set; }

    [XmlElement("DTPOSTED")]
    public string DatePosted { get; set; }

    [XmlElement("TRNAMT")]
    public double TransactionAmount { get; set; }
}

我的問題是元素再次包裹在元素中，結果得到以下輸出

...
    <STMTTRN> <!-- This does not match my Original XML -->
      <STMTTRN>
        <TRNTYPE>CHECK</TRNTYPE>
        <DTPOSTED>20051004</DTPOSTED>
        <TRNAMT>-200.00</TRNAMT>
      </STMTTRN>
      <STMTTRN>
        <TRNTYPE>ATM</TRNTYPE>
        <DTPOSTED>20051020</DTPOSTED>
        <TRNAMT>-300.00</TRNAMT>
      </STMTTRN>
    </STMTTRN>

注意：從 List 屬性中移除 [XmlArray("STMTTRN")] 標簽不會解決這個問題，而是

如果有人可以糾正我或給我一個更好的解決方案，那就太好了！！

Answer 1

如果您希望每個項目的元素沒有包裝元素，則應為[XmlElement] ：

[XmlElement("STMTTRN")]
public List<StatementTransaction> StatementTransactions { get; set; }

Answer 2

我想補充一點，為了序列化集合，你需要有這樣的東西：

[Serializable]
[XmlRoot("BANKTRANLIST", Namespace = "http://bank.net", IsNullable = false)]
public class BankTransactionList
{
    public BankTransactionList()
    {
        StatementTransactions = new List<StatementTransaction>()
        {
            new StatementTransaction()
        };
    }

    [XmlElement("DTSTART")]
    public string StartDate { get; set; }

    [XmlElement("DTEND")]
    public string EndDate { get; set; }

    [XmlElement("STMTTRN")]
    public List<StatementTransaction> StatementTransactions { get; set; }
}

否則，不初始化StatementTransaction對象，列表將不會被序列化。
