我想获取标头为<？xml version = \“ 1.0 \” encoding = \“ UTF-8 \” Standalone = \“ yes \”？>的XML

问题描述

使用下面的代码序列化XmlSerializer对象

<?xml version=\"1.0\" encoding=\"UTF-8\"?> 

代码：

private static bool StudentsReport(string filePath,Students std)
{
       XmlSerializerNamespaces namespaces = new XmlSerializerNamespaces(new[] { XmlQualifiedname.Empty });

        XmlSerializer serializer = new XmlSerializer(typeof(Students));

        XmlWriterSettings settings = new XmlWriterSettings
        {
            Indent = true,OmitXmlDeclaration = true,};

        using (XmlWriter writer = XmlWriter.Create(filePath,settings))
        {
            serializer.Serialize(writer,std,namespaces );
        }

        return true;
 }

学生类别为：

public class Students
{
        private string studentID;
        private string studentName;

        /// <summary>
        /// To store Machine Details.
        /// </summary>
        public string ID
        {
            get { return this.studentID; }
            set { this.studentID = value; }
        }

        [System.Xml.Serialization.XmlAttributeAttribute()]
        public string Name
        {
            get { return this.studentName; }
            set { this.studentName = value; }
        }
}

解决方法

使用standalone方法添加WriteStartDocument值。

XmlWriterSettings settings = new XmlWriterSettings
{
    Indent = true,//OmitXmlDeclaration = true,// must be false
};

using (XmlWriter writer = XmlWriter.Create(filePath,settings))
{
    writer.WriteStartDocument(standalone: true);
    serializer.Serialize(writer,std,namespaces);
}

一些提示。

将Students类重命名为Student。因为它描述的是一个学生，而不是一个学生。

ID属性重命名为Id。参见Naming Guidelines

更改方法签名：void StudentReport。总是返回相同的bool值是没有意义的。
