C# 显示数据视图信息

如何使用

单选按钮对分配给数据视图的信息进行排序

private void btnSearchByGender_Click(object sender, EventArgs e)
{
    DataView data = new DataView(pID2dbDataSet.customer);

    data.RowFilter = "Gender=" + rdoMale.Select();
    customerDataGridView.DataSource = data;
}

到目前为止，我已经得到了这个，但我不知道如何选择单选按钮的作用

private void btnSearchByGender_Click(object sender, EventArgs e)
{
    DataView data = new DataView(pID2dbDataSet.customer);

    string gender;
    if (rdoMale.Checked)
        gender = "Male"
    else
       gender = "Female"
    data.RowFilter = "Gender = '" + gender + "'";
    customerDataGridView.DataSource = data;
}
