Question

我正在尝试写入.xml文件。问题是，当我写作时，我收到错误消息：无法从'int'转换为'string'。现在我知道这意味着我需要将整数转换为字符串，但我对如何做到这一点很困惑。该我正在使用的代码如下：

  private void GetProperties()
        {
        //CreateNode(everything being referenced. Put text boxes, and drop down boxes here.
        XmlTextWriter writer = new XmlTextWriter(@"C:\ForteSenderv2.0\Forte.dat", System.Text.Encoding.UTF8);
        writer.WriteStartDocument(true);

        //Making the code indeted by 2 characters.
        writer.Formatting = Formatting.Indented;
        writer.Indentation = 2;

        //Making the start element "Table".
        writer.WriteStartElement("Forte_Data_Gatherer_Application");
        //Calling the rst of the .xml file to write.
        CreateNode(Portbx.SelectedIndex, BaudRatebx.SelectedIndex, Databitsbx.SelectedIndex, Paritybx.SelectedIndex, StopBitsbx.SelectedIndex, Handshakingbx.SelectedIndex, writer);
        writer.WriteEndElement();
        writer.WriteEndDocument();
        writer.Close();

    }

错误在CreateNode(Portbx.SelectedIndex, BaudRatebx.SelectedIndex, Databitsbx.SelectedIndex, Paritybx.SelectedIndex, StopBitsbx.SelectedIndex, Handshakingbx.SelectedIndex, writer);

处开始

Answer 1

从整数到字符串没有隐式转换。您需要在索引参数上调用ToString()：

CreateNode(Portbx.SelectedIndex.ToString(), ...

或者您需要更改CreateNode的签名以获取整数

CreateNode(int Port, ...

写入.xml文件错误消息
