如何使用单选按钮在每个问题后保留空格使用flowLayoutPanel以窗口形式显示c＃是他们有机会使用带有flowLayoutPanel的css，这样看起来和字段都会很好我的示例代码
for (int i = 0, r = 0; i < dt.Rows.Count; i++, r++)
{
Label lblQuestionNo = new Label();
Label lblQuestion = new Label();
Label lblCorrectAnswer = new Label();
lblQuestionNo.Text += Convert.ToInt32(r + 1).ToString();
lblQuestionNo.ForeColor = System.Drawing.Color.Red;
string ques = dt.Rows[r]["Question"].ToString();
lblQuestion.Text += dt.Rows[r]["Question"].ToString();
lblQuestion.Text += Environment.NewLine;
lblQuestionNo.Text += Environment.NewLine;
Label lblOption1 = new Label();
Label lblOption2 = new Label();
Label lblOption3 = new Label();
Label lblOption4 = new Label();
Label lblOption5 = new Label();
Label lblOpt1 = new Label();
Label lblOpt2 = new Label();
Label lblOpt3 = new Label();
Label lblOpt4 = new Label();
Label lblOpt5 = new Label();
Label lblBreak = new Label();
Label lblBreaks = new Label();
lblBreaks.Text = "<br />";
lblBreak.Text = "<br />";
if (Convert.ToInt32(dt.Rows[r]["AnswerType"]) == 0)
{
RadioButton rb1 = new RadioButton();

rb5.Enabled = false;
lblOption1.Text += dt.Rows[r]["Option1"].ToString();
lblOption2.Text += dt.Rows[r]["Option2"].ToString();
if (dt.Rows[r]["Option3"].ToString() != null && dt.Rows[r]["Option3"].ToString() != "")
lblOption3.Text += dt.Rows[r]["Option3"].ToString();
else
rb3.Visible = false;

lblOption5.Text += dt.Rows[r]["Option5"].ToString();
else
rb5.Visible = false;
String CorrectAnswer = dt.Rows[r]["CorrectAnswer"].ToString();
switch (CorrectAnswer)
{
case "A":

}
}
flowLayoutPanel1.Controls.Add(lblQuestionNo);
flowLayoutPanel1.Controls.Add(lblQuestion);
flowLayoutPanel1.WrapContents = true;
flowLayoutPanel1.Controls.Add(rb1);
flowLayoutPanel1.Controls.Add(lblOption1);
flowLayoutPanel1.Controls.Add(lblOpt1);
flowLayoutPanel1.Controls.Add(rb2);
flowLayoutPanel1.Controls.Add(lblOption2);

您需要设置保证金属性。 喜欢
Button btn = new Button();
btn.Name = btn.Text = string.Format("Button{0}", i + 1);
btn.Margin = new Padding(5, 5, 5, 5);
flowLayoutPanel1.Controls.Add(btn);
