Question

我想创建一个xml文档并将其保存在字符串对象中。

我在SO上提到这两个问题是为了保存和编码目的

我的代码：

StringBuilder builder = new StringBuilder();

XDocument doc = new XDocument(new XElement("BANKID",
       new XElement("ReqID", "WEB"),
       new XElement("ReqHeader", "CASHDEP"),
       new XElement("CurrencyCode", ""),
       new XElement("CurrencyAbbrivation", "")));

using (TextWriter writer = new Utf8StringWriter(builder)) // Error Line
{
doc.Save(writer);
}
builder.ToString();

public class Utf8StringWriter : StringWriter
{
    public override Encoding Encoding { get { return Encoding.UTF8; } }        
}

它给出了错误说＆＃34; Utf8StringWriter不包含带有1个参数的构造函数＆＃34;

如何修改接受StringBuilder参数的类？

Answer 1

您的自定义Utf8StringWriter类没有构造函数接受参数，但您尝试将值传递给它。这就是您收到错误消息的原因。

添加一个接受StringBuilder的公共构造函数，然后将其传递给基类：

public class Utf8StringWriter : StringWriter
{
    public Utf8StringWriter(StringBuilder stringBuilder)
        :base(stringBuilder)
    {
    }

    public override Encoding Encoding { get { return Encoding.UTF8; } }
}
