SQL 行作为复选框

Question

我有一个员工 Web 表单，可以在其中将员工分配到任意数量的市场。我正在尝试获取 SQL 行值并将它们分配给 C# 中的复选框。

例如，我的 SQL 数据库将如下所示：

EmployeeID  MarketID
99999       1
99999       2
99999       4

我后面的代码是

string sqlConn = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
using (SqlConnection sqlConnection1 = new SqlConnection(sqlConn))
{
    using (SqlCommand cmd = new SqlCommand())
    {
        cmd.CommandText = ("usp_EmployeeMarkets");
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.Connection = sqlConnection1;
        cmd.Parameters.AddWithValue("EmployeeID", id);
        sqlConnection1.Open();

        SqlDataReader sdr = cmd.ExecuteReader();

        while (sdr.Read())
        {
            Market1CheckBox.Checked = sdr["MarketID"].Equals(1);
            Market2CheckBox.Checked = sdr["MarketID"].Equals(2);
            Market3CheckBox.Checked = sdr["MarketID"].Equals(3);
            Market4CheckBox.Checked = sdr["MarketID"].Equals(4);
        }
    }
}

所以在上面的例子中，复选框 1、2、4 应该被选中，而复选框 3 不应该被选中。显然这是不正确的，因为我已经检查了 none 个复选框。我怎样才能完成我想要做的事情？

Answer 1

这是我最后做的事情：

string sqlConn = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
using (SqlConnection sqlConnection1 = new SqlConnection(sqlConn))
{
    using (SqlCommand cmd = new SqlCommand())
    {
        cmd.CommandText = ("usp_EmployeeMarkets");
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.Connection = sqlConnection1;
        cmd.Parameters.AddWithValue("EmployeeID", id);
        sqlConnection1.Open();

        SqlDataReader sdr = cmd.ExecuteReader();

        while (sdr.Read())
        {
            string value = sdr["MarketID"].ToString();
            if (value == "1")
            {
                Market1CheckBox.Checked = true;
            }
            if (value == "2")
            {
                Market2CheckBox.Checked = true;
            }
            if (value == "3")
            {
                Market3CheckBox.Checked = true;
            }
            if (value == "4")
            {
                Market4CheckBox.Checked = true;
            }
        }
    }
}

Answer 2

  List<string> listOfMarkets=new List<string>();    
   while (sdr.Read())
    {
        listOfMarkets.Add(sdr["MarketID"].ToString());
    }
        Market1CheckBox.Checked = listOfMarkets.Contains("1")?true:false;
        Market2CheckBox.Checked = listOfMarkets.Contains("2")?true:false;
        Market3CheckBox.Checked = listOfMarkets.Contains("3")?true:false;
        Market4CheckBox.Checked =listOfMarkets.Contains("4")?true:false;
