克服在DataGridView中显示二进制列的.NET问题

dataGridView1.Rows.Add(Convert.ToString(binaryData, 2));

dataGridView1.Columns["binaryColumn"].DefaultCellStyle.Format = "X2";

public class BinaryCell : DataGridViewTextBoxCell
{
    public override object DefaultNewRowValue
    {
        get { return ""; }
    }

    public override Type ValueType
    {
        get { return typeof(byte[]); }
    }

    public override object ParseFormattedValue(object formattedValue, DataGridViewCellStyle cellStyle, TypeConverter formattedValueTypeConverter, TypeConverter valueTypeConverter)
    {
        if (formattedValue is string)
        {
            byte[] binaryData = new byte[0];
            try
            {
                binaryData = Convert.FromBase64String((string)formattedValue);
            }
            catch { }
            return binaryData;
        }
        return base.ParseFormattedValue(formattedValue, cellStyle, formattedValueTypeConverter, valueTypeConverter);
    }

    public override object GetFormattedValue(object value, int rowIndex, ref DataGridViewCellStyle cellStyle, TypeConverter valueTypeConverter, TypeConverter formattedValueTypeConverter)
    {
        if (value is byte[])
        {

dataGridView1.Columns["binaryColumn"].CellTemplate = new BinaryCell();
