    RadioButton rb = (RadioButton)sender;//获取当前点击的radiobutton

    int tag = Convert.ToInt32(rb.Tag.ToString());

    switch (tag)

            label7.Text = "分类";

            label7.Text = "分类";
            break;

            label7.Text = "借款人";
            break;
    }
    this.Text = titletextOut;//窗口的text
    //IniAccoutCombobox(cbbAccout);
    //IniBorrowerCombobox(cbbSort, "0");
    //IniBorrowerCombobox(cbbSort, "1");
    //IniSortCombobox(cbbSort, "0");
