将PrinterSettings序列化为字符串或blob以插入到数据库中

using System.Xml.Serialization;

// 创建PrinterSettings对象
PrinterSettings printerSettings = new PrinterSettings();

// 创建XmlSerializer对象
XmlSerializer serializer = new XmlSerializer(typeof(PrinterSettings));

// 创建StringWriter对象，用于存储序列化后的XML字符串
using (StringWriter writer = new StringWriter())
{
    // 序列化PrinterSettings对象到StringWriter
    serializer.Serialize(writer, printerSettings);

    // 获取序列化后的XML字符串
    string serializedXml = writer.ToString();

    // 将serializedXml插入到数据库中
    // ...
}

using System.IO;
using System.Runtime.Serialization.Formatters.Binary;

// 创建PrinterSettings对象
PrinterSettings printerSettings = new PrinterSettings();

// 创建BinaryFormatter对象
BinaryFormatter formatter = new BinaryFormatter();

// 创建MemoryStream对象，用于存储序列化后的二进制数据
using (MemoryStream stream = new MemoryStream())
{
    // 序列化PrinterSettings对象到MemoryStream
    formatter.Serialize(stream, printerSettings);

    // 获取序列化后的字节数组
    byte[] serializedBytes = stream.ToArray();

    // 将serializedBytes插入到数据库中
    // ...
