将打印机设置序列化为字符串或 Blob 以插入到数据库中

Question

使用以下代码，我可以将打印机设置序列化/反序列化为文件。 我想问一下是否有办法将其序列化为字符串或字节数组或类似内容，以便将其直接保存到数据库中。

谢谢！

PrinterSettings prtSettings = new PrinterSettings();
prtSettings.PrintFileName = "does not matter, unused if PrintToFile == false";
//serialise
System.Xml.Serialization.XmlSerializer xmlSerializer = new         System.Xml.Serialization.XmlSerializer(prtSettings.GetType());
using (System.IO.TextWriter txtWriter = new     StreamWriter(@"c:tempprinterSettings.xml"))
{
xmlSerializer.Serialize(txtWriter,prtSettings);
}
//deserialise
using (FileStream fileStream = new FileStream(@"c:tempprinterSettings.xml", FileMode.Open))
{
object obj = xmlSerializer.Deserialize(fileStream);
prtSettings = (PrinterSettings)obj;
}

而不是 StreamWriter 使用 StringWriter

string printerSettingText = "";
XmlSerializer xser = new XmlSerializer(typeof(PrinterSettings));
using (StringWriter sw = new StringWriter())
{
xser.Serialize(sw, prtSettings);
printerSettingText = sw.ToString();
}

对象的反序列化很简单，如下所示

string dataToDeserialize = GetYourDataFromDb();
xser = new XmlSerializer(typeof(PrinterSettings));
using (StringReader sr = new StringReader(dataToDeserialize))
{
PrinterSettings prn = (PrinterSettings)xser.Deserialize(sr);
Console.WriteLine(prn.PrintFileName);
}
