How I can search rows in a datatable with a searchstring?

Question

I want to search rows in my DataTable.

I\'ve tried this:

 protected void imggastsuche_Click(object sender, EventArgs e) 
        {

Static method for search any column

public static DataTable SearchInAllColums(DataTable table, string keyword)
{
    StringComparison comparison = StringComparison.OrdinalIgnoreCase;

    if (keyword.Equals(""))
    {
        return table;
    }

    DataRow[] filteredRows = table.Rows
           .Cast()
           .Where(r => r.ItemArray.Any(
           c => c.ToString().IndexOf(keyword, comparison) >= 0))
           .ToArray();

    if (filteredRows.Length == 0)
    {
        DataTable dtTemp = table.Clone();
        dtTemp.Clear();
        return dtTemp;
    }
    else
    {
        return filteredRows.CopyToDataTable();
    }
}
