C# CSV to XML Conversion, CSV to XML Conversion using LINQ

How to Convert CSV to XML using C#

Language Integrated Query (LINQ) can be used to convert a CSV file to XML. Here is the sample CSV file that needs to be converted

The following code reads the CSV file to an array. LINQ is used to loop through the array and the contents are written as XML using XElement (System.XML.Linq).


public void ConvertCSVToXML()

{

String[] FileContent = File.ReadAllLines(@"C:\Temp\vba.csv");

String XMLNS = "";

XElement Inv = new XElement("Invoice",

from items in FileContent

let fields = items.Split(',')

select new XElement("Item",

new XElement("ID", fields[0]),

new XElement("Name", fields[1]),

new XElement("Price", fields[2]),

new XElement("Availability", fields[3]),

new XElement("TotalPrice", fields[4])

)

);

File.WriteAllText(@"C:\Temp\vba.xml", XMLNS + Inv.ToString() );

}

Here is the Input Text File


The output XML looks like

  2. how does the array know how many fields it has?
    so the array string dosnt define how many fields it has?

    I add more fields but i dont know how to tell the array that there are more fields.

    ERROR:
    Index was outside the bounds of the array.
