Datatable dan dönen değerleri çift dizili matrise çeviren method örneği.     

private static string[][] ConvertToArray(DataTable veri, int dizi)
        {
            string[][] veriler = new string[veri.Rows.Count][];

            int k = 0;
            foreach (DataRow r in veri.Rows)
            {

String.RemoveMany (Extension Method)

public static string RemoveMany(this string dirtyString, params string[] stringsToRemove)
{
            return dirtyString.Split(stringsToRemove, StringSplitOptions.None)
           .Aggregate((sentence, next) => sentence + next)

}

Kullanımı:
string dirty = "This is ABCa st)r(ing.";
string dirty2 = "tDEFes.t-";
string[] delims = new string[] { "ABC", "(", ")" };
Console.WriteLine(dirty.RemoveMany(delims));
Console.WriteLine(dirty2.RemoveMany("DEF", ".", "-"));
//output
"This is a string."
"test"
