如何检索和从数据库中C＃

Question

显示的单选按钮的值I有两个单选按钮：Yes和No.

我存储选择的值（0或1）到SQL数据库。现在我想在使用数据集加载表单时将这些单选按钮的值从数据库显示给用户。 这里是我的代码：

public void LoadRequestInfo() 
    { 
     CommonCollection c = new CommonCollection(); 
     var CTS = c.COMPTRACKERCONNECTIONSTRING(); 
     var CTS_conn = new SqlConnection(CTS.ConnectionString); 
     try 
     { 
      SqlCommand cmd = new SqlCommand("CTS_GetRequest", CTS_conn); 
      cmd.CommandType = CommandType.StoredProcedure; 
      cmd.Parameters.Add(new SqlParameter("@ID", "100221")); 
      cmd.Parameters.Add(new SqlParameter("@RequestId", "CD558017-8CEA-496D-9537-A53E1E2BA8AD")); 
      cmd.Parameters.Add(new SqlParameter("@UserID", Microsoft.SharePoint.SPContext.Current.Web.CurrentUser.ID)); 
      SqlDataAdapter da = new SqlDataAdapter(cmd); 
      DataSet ds = new DataSet(); 
      CTS_conn.Open(); 
      da.Fill(ds); 
      CTS_conn.Close(); 

      if (ds != null && ds.Tables[0].Rows.Count > 0) 
      { 
       txtTitle.Text = ds.Tables[0].Rows[0][17].ToString(); 
       drpProperty.SelectedItem.Text = ds.Tables[0].Rows[0][2].ToString(); 
       drpCategory.SelectedValue = ds.Tables[0].Rows[0][3].ToString(); 
       rdYes.Checked = ds.Tables[0].Rows[0][12].ToString(); //Here is the part I have problem. 
       rdNo.Checked = ds.Tables[0].Rows[0][14].ToString(); 
      } 
     } 
     } 

Answer 1

我能够显示单选按钮的结果：

Boolean IsYes = Boolean.Parse(ds.Tables[0].Rows[0][12].ToString()); 
if (IsYes == true) 
{ 
    rdYes.Checked = true; 
    txtPenalty.Visible = true; 
} 

else if (IsYes == false) 
{ 
    rdNo.Checked = true; 
    txtPenalty.Visible = false; 
}
