如何改变生成的xml的编码方式.

[maxiaosong]

序列化后生成的XML的头部
<?xml version="1.0" encoding="utf-16"?>
我想让生成的XML的编码格式
<?xml version="1.0" encoding="utf-8"?>
怎么办

代码如下
public static string Serialization(Report report)
{
StringBuilder sb = new StringBuilder();
TextWriter writer = new StringWriter(sb);
XmlSerializer serializer = new XmlSerializer(report.GetType());
serializer.Serialize(writer,report);
return sb.ToString();
}

XmlDocument doc = new XmlDocument();
doc.LoadXml(sb.ToString(););
XmlDeclaration dec = doc.FirstChild as XmlDeclaration;
dec.Encoding = "utf-8";
return doc.OuterXml;
