如何從C＃asp.net中的數據庫獲取復選框值

Question

這是我到目前為止所擁有的。

//Getting access value from the AccessTable

SqlCommand cmadAccess;
string strAccess;
strAccess = "select * from AccessTable where Email='" +
    EmailTextBox.Text.Trim() + "'";
cmadAccess = new SqlCommand(strAccess, conn);
SqlDataReader readAccess = cmadAccess.ExecuteReader();
if (readAccess.Read()) {
    //here I am trying to display data from the database to the checkbox but it does not work.
}

這是我嘗試過的兩個示例：

TechnitianCheckBox.Checked = Convert.ToBoolean(readAccess["ClientTechnitian"]);

TechnitianCheckBox.Checked = readAccess["ClientTechnitian"].ToString();

任何人都可以指出正確的方法嗎？

Answer 1

您正在閱讀器上尋找GetOrdinal(...) 。

TechnitianCheckBox.Checked = readAccess.GetBoolean(readAccess.GetOrdinal("ClientTechnitian"));
