本文給大家分享一下C#操作（讀取、寫入）XML文檔的實用方法，這種方法主要是對比較規范的XML文檔進行操作，因為它（XML文檔）和類對象是嚴格對應的，否則在反序列或序列化的時候會出現錯誤。其他的不用多說，直接看示例代碼吧：
? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111

static void Main(string[] args)
{
//序列化對象生成文件
WriteSingleXML();
//反序列化文件生成對象
ReadListXML();
Console.ReadKey();
}
/// <summary>

/// </summary>
private static void ReadListXML()
{
//反序列化文件
Console.WriteLine("反序列化XML文件為集合");
var reader = new XMLSerializer(typeof(List<UserInfo>));
using (var fs = File.OpenRead("UserInfo.XML"))
{
var result = reader.Deserialize(fs) as List<UserInfo>;
result.ForEach(Console.WriteLine);
}
Console.WriteLine("反序列化成功");
}
/// <summary>
/// 序列化對象到XML文件
/// </summary>
private static void WriteSingleXML()
{
//序列化集合為XML文件
Console.WriteLine("序列化集合為XML文件");
var reader = new XMLSerializer(typeof(List<UserInfo>));
//寫入文件
using (var fs = File.OpenWrite("UserInfo.XML"))
{
reader.Serialize(fs, list);
}
Console.WriteLine("寫入成功");
}
}
}
運行結果如圖：
生成的XML文檔如下:
