问题描述
我将如何像这样写出xml
How would i write the xml out like
<?xml version="1.0" encoding="UTF-8"?>
<calibration>
<ZoomLevel 250>0.0100502512562814</ZoomLevel 250>
<ZoomLevel 250>0.0100502512562814</ZoomLevel 250>
........
</calibration>
我知道如何写出来,但是我无法在需要atm的循环中写出来,因为我写xml表是
I know how to write it out but i cant write it out in a loop which i need to atm the i have for writting the xml sheet is
public void XMLWrite(Dictionary<string, double> dict)
{
//write the dictonary into an xml file
XmlDocument doc = new XmlDocument();
XmlNode docNode = doc.CreateXmlDeclaration("1.0", "UTF-8", null);
doc.AppendChild(docNode);
XmlNode productsNode = doc.CreateElement("calibration");
doc.AppendChild(productsNode);
foreach (KeyValuePair<string, double> entry in dict)
{
XmlNode zoomNode = doc.CreateElement("ZoomLevel");
XmlAttribute ZoomLevel = doc.CreateAttribute(entry.Key.ToString());
//XmlElement PixelSize = doc.CreateElement (entry.key = entry.Value.ToString());
zoomNode.Attributes.Append(ZoomLevel);
productsNode.AppendChild(zoomNode);
}
doc.Save(pathName);
}
推荐答案
其他人说您想要的xml无效.我注意到的另一件事是,在您的示例中,有两个节点的级别缩放为 250 ,这是字典的键,并且您知道它应该是 unique .但是,我建议您使用 LINQ to XML (System.Xml.Linq
),它更简单,那怎么办:
As the others said your wanted xml isn't valid. Another thing that I noticed is that in your example there are two nodes with the level zoom of 250 which is a key of the dictionary and as you know it should be unique.However I recommend you to use LINQ to XML (System.Xml.Linq
) which is simpler, so what about:
public void XMLWrite( Dictionary<string, double> dict ) {
//LINQ to XML
XDocument doc = new XDocument( new XElement( "calibration" ) );
foreach ( KeyValuePair<string, double> entry in dict )
doc.Root.Add( new XElement( "zoom", entry.Value.ToString( ), new XAttribute( "level", entry.Key.ToString( ) ) ) );
doc.Save( pathName );
}
我通过传递了此字典来测试了这段代码:
I tested this code by passing this dictionary:
"250", 0.110050251256281
"150", 0.810050256425628
"850", 0.701005025125628
"550", 0.910050251256281
结果是:
<?xml version="1.0" encoding="utf-8"?>
<calibration>
<zoom level="250">0,110050251256281</zoom>
<zoom level="150">0,810050256425628</zoom>
<zoom level="850">0,701005025125628</zoom>
<zoom level="550">0,910050251256281</zoom>
</calibration>
