There is a SelectedItems property that will return the selected items in the DataGrid. In your case you could each such item to a DataRowView, e.g.:

StringBuilder sb = new StringBuilder();
foreach(var selectedRow in DataGrid_Table.SelectedItems.OfType<DataRowView>())
{
    foreach(DataColumn column in selectedRow.DataView.Table.Columns)
    {
        sb.Append(selectedRow[column.ColumnName] + ";");
    }
    sb.Append(Environment.NewLine);
}

string export = sb.ToString();
