Question

I have a datatable on which I am applying Select() method. After that I want to get the result into an array of String. I have tried the following code but it is not working.
Please let me know the exact solutions for this.

 DataTable dtget = HttpContext.Current.Cache["Hello"] as DataTable; 
    string sqlFilter = "Securityid = '" + CommonClass.Encryptdata(txtSecurity.Text) + "'";
    DataRow[] dr = dtget.Select(sqlFilter);
    if (dr.Length > 0)
    {
        String[] Con;
        for (int i = 0; i <= dr.Length; i++)
        {
            dr[i] = dr[i].ToString();

        }
    }

You have to create the List<T>.

Something like this:

 List<String[]> list=new List<String[]>();

   if (dr.Length > 0)
    {
        for (int i = 0; i < dr.Length; i++)
        {
            string []ar=new string[dtget.Columns.Count];
            for(int j=0;j<dtget.Columns.Count;j++)
             {
              ar[j]=dr[i][j].ToString();
             }
             list.Add(ar);
        }
    }
