如何从C＃中的文件夹中选择所有xml文件并解析它们

我已经解决了这个问题，但想与您分享这个解决方案。

注意：这仅适用于内容相同的xml文件。

让我告诉你我如何解决它：

第一步：我已经按照xml文件中的xml结构创建了一个类

[XmlRoot("Data")]
public class Data
{
    [XmlElement("Msg")]
    public Msg Msgs { get; set; }
}


public class Msg
{
    [XmlElement]
    public string Type { get; set; }
    [XmlElement]
    public string UserID { get; set; }
    [XmlElement]
    public string SerialNumber { get; set; }
    [XmlElement]
    public string DateTime { get; set; }
    [XmlElement("Rows")]
    public Rows RowsObj { get; set; }
}
public class Rows
{

    [XmlElement("Row")]
    public List<Row> RowsList { get; set; }
}

public class Row
{
    [XmlElement]
    public string InvoiceCode { get; set; }
    [XmlElement]
    public string ServiceCode { get; set; }
    [XmlElement]
    public string BranchID { get; set; }
    [XmlElement]
    public string AbonCode { get; set; }
    [XmlElement]
    public string Amount { get; set; }
    [XmlElement]
    public string PaymentDate { get; set; }
    [XmlElement]
    public string ReceiptNumber { get; set; }
    [XmlElement]
    public string PaymentSite { get; set; }
    [XmlElement]
    public string PaymentInstrument { get; set; }
    [XmlElement]
    public string BankHeadOfficeCode { get; set; }
}

这是我的.xml文件结构

<?xml version="1.0" encoding="utf-8"?>
<Data>
  <Header/>
  <Msg>
    <Type>INVOICE_PAY_APUS</Type>
    <UserID>888888</UserID>
    <SerialNumber>8210089</SerialNumber>
    <DateTime>2015-04-15T15:20:17</DateTime>
    <Rows>
        <Row>
            <InvoiceCode>1414016335DR</InvoiceCode>
            <BranchID>981008</BranchID>
            <AbonCode>1414016335</AbonCode>
            <Amount>80.00</Amount>
            <PaymentDate>2015-04-15T15:20:03</PaymentDate>
            <ReceiptNumber>95037101</ReceiptNumber>
            <PaymentSite>GPP</PaymentSite>
            <PaymentInstrument>4</PaymentInstrument>
            <BankHeadOfficeCode>qwerty</BankHeadOfficeCode>
        </Row>
        <Row>
            <InvoiceCode>1414016335XH</InvoiceCode>
            <BranchID>981005</BranchID>
            <AbonCode>1414016335</AbonCode>
            <Amount>34.00</Amount>
            <PaymentDate>2015-04-15T15:20:03</PaymentDate>
            <ReceiptNumber>95037103</ReceiptNumber>
            <PaymentInstrument>4</PaymentInstrument>
            <PaymentSite>GPP</PaymentSite>
            <BankHeadOfficeCode>AZRTAZ22</BankHeadOfficeCode>
        </Row>
    </Rows>
  </Msg>
</Data>

如您所见，我在Data等下方有一个称为Data和Msg的根元素。

第二步：

在控制台应用程序的主类中，我试图到达放置xml文件的文件夹，然后，我从xml中读取数据并将其解析为对象。

class Program
{
    static void Main(string[] args)
    {



        string mainPath = "C:\\xmlTest"; //folder with my xml files goes here, it's optional, you can change it to whatever you want
        Data data = new Data();

        foreach (string file in Directory.EnumerateFiles(mainPath, "*.xml"))
        {
            XmlSerializer mySerializer = new XmlSerializer(typeof(Data));
            StreamReader streamReader = new StreamReader(file);

            data = (Data)mySerializer.Deserialize(streamReader);
            streamReader.Close();
            List<Row> rows = data.Msgs.RowsObj.RowsList;

            foreach (var row in rows)
                    {
                        //do stuff here
                        //example: string paymentType = row.InvoiceCode.Substring(row.InvoiceCode.Length - 2);
                    }



        }
    }
}

就是这样，希望对您有所帮助。
