I found this code on Microsoft forum. This is so far one of easiest way, easy to understand and use. This has saved me hours. I have customized this as extension method without any change to actual implementaion. Below is the code. it doesn't require much explanation.

You can use two function signature with same implementation

1) public static DataSet ToDataSetFromObject(this object dsCollection)

2) public static DataSet ToDataSetFromArrayOfObject( this object[] arrCollection). I'll be using this one in below example.

// 

// Serialize Object to XML and then read it into a DataSet:
// 
// Array of object
// dataset

public static DataSet ToDataSetFromArrayOfObject( this object[] arrCollection)
{
    DataSet ds = new DataSet();
    try {
        XmlSerializer serializer = new XmlSerializer(arrCollection.GetType);
        System.IO.StringWriter sw = new System.IO.StringWriter();
        serializer.Serialize(sw, dsCollection);
        System.IO.StringReader reader = new System.IO.StringReader(sw.ToString());
        ds.ReadXml(reader);
    } catch (Exception ex) {
        throw (new Exception("Error While Converting Array of Object to Dataset."));
    }
    return ds;
}

To use this extension in code

Country[] objArrayCountry = null;
objArrayCountry = ....;// populate your array
if ((objArrayCountry != null)) {
    dataset = objArrayCountry.ToDataSetFromArrayOfObject();
}
