I'm very new to C# programming, here's my first question. I'd like to read the attribute named ID of window and then parse it into an int.
Here's my XML document:
<window ID="0">
<parentID>0</parentID>
<windowType>0</windowType>
<windowName>firstWindow</windowName>
<windowText>My first window</windowText>
<windowOptions>Option 1; Option 2;</windowOptions>
<windowActions>Action 1; Action 2;</windowActions>
<windowExit>Exit Action;</windowExit>
</window>
Here's my C# code, it should read the information from the XML files and then parse them into a 2D array.
string[][] windowResults;
using (XmlReader reader = XmlReader.Create("GUI.xml"))
{
int windowCount = 0;
int nodeCount = 0;
int windowID = 0;
while (reader.Read())
{
if (reader.NodeType == XmlNodeType.Element &&
reader.Name == "window")
{
nodeCount++;
}
}
windowResults = new string[nodeCount][];
while (reader.Read())
{
switch (reader.NodeType)
{
case XmlNodeType.Element:
if (reader.Name == "window")
{
while (reader.MoveToNextAttribute())
{
int.TryParse(reader.Value, out windowID);
}
}
break;
case XmlNodeType.Text:
switch (reader.Value)
{
case "parentID":
windowResults[windowID][1] = reader.Value;
break;
case "windowType":
windowResults[windowID][2] = reader.Value;
break;
case "windowText":
windowResults[windowID][3] = reader.Value;
break;
case "windowOptions":
windowResults[windowID][4] = reader.Value;
break;
case "windowActions":
windowResults[windowID][5] = reader.Value;
break;
case "windowExit":
windowResults[windowID][6] = reader.Value;
break;
}
break;
case XmlNodeType.EndElement:
switch (reader.Name)
{
case "window":
windowCount++;
break;
}
break;
}
}
}
Currently it gives me the following error:
'int' is a 'type' but is used like a 'variable'
The same using LINQ to XML:
using System.Collections.Generic;
using System.Linq;
using System.Xml.Linq;
private static IEnumerable<Window> ReadWindows(string path)
{
XDocument doc = XDocument.Load(path);
return from w in doc.Root.Elements("window")
select new Window((int)w.Attribute("ID"))
{
ParentID = (int?)w.Element("parentID"),
Type = (string)w.Element("windowType"),
Name = (string)w.Element("windowName"),
Text = (string)w.Element("windowText"),
Options = (string)w.Element("windowOptions"),
Actions = (string)w.Element("windowActions"),
Exit = (string)w.Element("windowExit"),
};
}
A sequence of the following classes will be constructed:
class Window
{
public Window(int id) { this.ID = id; }
public int ID { get; private set; }
public int? ParentID { get; set; }
public string Type { get; set; }
public string Name { get; set; }
public string Text { get; set; }
public string Options { get; set; }
public string Actions { get; set; }
public string Exit { get; set; }
}
