Hi everybody,
Does anybody there can help me with tha traslation of the next code C# to VB.NET? I'm working in WPF Application (VB.NET).
NOTE: I have a problem with the part: ' // Create the query

var rowsFromFile = from c in XDocument.Load(
                           "MyData.xml").Elements lang="sql">"Data").Elements("Rows").Elements("Row")
                                  select c;



I can't found the traslation.

        public void Save(System.Windows.Data.CollectionView items)
        {
            XDocument xdoc = new XDocument();

            XElement xeRoot = new XElement("Data");
            XElement xeSubRoot = new XElement("Rows");

            foreach (var item in items)
            {
                ListViewData lvc = (ListViewData)item;

                XElement xRow = new XElement("Row");
                xRow.Add(new XElement("col1", lvc.Col1));

                xeSubRoot.Add(xRow);

            if (File.Exists("MyData.xml"))
            {
                // Create the query
                var rowsFromFile = from c in XDocument.Load(
                            "MyData.xml").Elements(
                            "Data").Elements("Rows").Elements("Row")
                                   select c;

                // Execute the query
                foreach (var row in rowsFromFile)
                {
                    rows.Add(new ListViewData(row.Element("col1").Value,
                            row.Element("col2").Value));
                }
            }
            return rows;
        }
    }

"// Create the query" is the problem or the nonexistent var keyword is the problem?

Hi,
Yes, i have a problem with "var", apparently it doesn't exist. Why?
[no name] 16-Jul-13 21:35pm
   
Why? Because the designers of the VB.NET language did not include it. If you want to know specifically why they did not include it, you would need to go ask Microsoft.

When i do the convertion to VB.NET, i have an error with var. I take this example of:

So change "var" to a data type type that VB.NET supports.

The functionality of var hower does exist. Known as "Option Infer": http://msdn.microsoft.com/en-us/library/bb384665.aspx

Instead asking others to do your job for you (how else can one understand your request), you should learn the ways to do such translations automatically.



Good luck,

XAML is the same, it does not depend on C# or VB.NET.
