c# - 如何在向导事件步骤中执行 SQL 插入？

Question

在 asp:Wizard 的第一步，我使用 DirectoryServices 进行登录以进行身份​​验证。但后来我想获取 UserID、Date 和 SCOPE_IDENTITY() 并将其插入到表中。这是我试过的。当我点击下一步时，信息没有插入，但 AD 功能被正确检查。我不确定我做错了什么

protected void OnActiveStepChanged(object sender, EventArgs e)
    {
        //check for the employee in AD
        string Domain = "mydomain.local";
        string EmployeeID = txtEmpID.Text;
        string Password = txtPassword.Text;
        string ADStatus = null;

        // If the ActiveStep is changing to Step2, check to see whether the 
        // user authenticated the AD Login Process.  If it is, skip to the Step2 step.
        if (Wizard1.ActiveStepIndex == Wizard1.WizardSteps.IndexOf(this.WizardStep2))
        {
            if (AuthenticateActiveDirectory(Domain, EmployeeID, Password) == true)
            {
                //If success ...
                ADStatus = "Success";
                Session["SessionADStatus"] = ADStatus;


                string strDepartment = ddlDepartment.SelectedValue;
                SqlConnection conn1 = new SqlConnection(ConfigurationManager.ConnectionStrings["myconnection"].ConnectionString);
                SqlCommand cmd1 = new SqlCommand("INSERT INTO [pharm_OrderID](UserID, RequestType, CreateDate) values (@UserID, @RequestType, @CreateDate);", conn1);
                cmd1.CommandType = CommandType.Text;
                conn1.Open();

                string strUserID = txtEmpID.Text;
                cmd1.Parameters.Add("@UserID", SqlDbType.NVarChar, 50);
                cmd1.Parameters["@UserID"].Value = strUserID;

                string strRequestType = ddlReturnType.SelectedValue;
                cmd1.Parameters.Add("@ReturnType", SqlDbType.NVarChar, 50);
                cmd1.Parameters["@ReturnType"].Value = strRequestType;

                string strCreateDate = lblOrderAttemptTime.Text;
                cmd1.Parameters.Add("@CreateDate", SqlDbType.NVarChar, 50);
                cmd1.Parameters["@CreateDate"].Value = strCreateDate;

                conn1.Dispose();
                cmd1.Dispose();
                Wizard1.ActiveStepIndex = Wizard1.WizardSteps.IndexOf(this.WizardStep2);

            }
            else
            {
                ADStatus = "Failure";
                Session["SessionADStatus"] = ADStatus;
                lblADError.Visible = true;
                lblADError.Text = "Unable to authenticate Employee ID or Password.";
                Wizard1.ActiveStepIndex = Wizard1.WizardSteps.IndexOf(this.WizardStep1);
            }


        }

    }

我不是AD专家，但需要执行命令才能产生任何结果。

尝试添加

 cmd1.ExecuteNonQuery(); 

在配置连接和命令之前

using(SqlConnection conn1 = new SqlConnection(........))
using(SqlCommand cmd1 = new SqlCommand("INSERT INTO [pharm_OrderID]" + 
                                      "(UserID, RequestType, CreateDate) " + 
                                      "values (@UserID, @RequestType, @CreateDate);", conn1))
{
    conn1.Open();
    string strUserID = txtEmpID.Text;
    cmd1.Parameters.Add("@UserID", SqlDbType.NVarChar, 50);
    cmd1.Parameters["@UserID"].Value = strUserID;

    string strRequestType = ddlReturnType.SelectedValue;
    cmd1.Parameters.Add("@ReturnType", SqlDbType.NVarChar, 50);
    cmd1.Parameters["@ReturnType"].Value = strRequestType;

    string strCreateDate = lblOrderAttemptTime.Text;
    cmd1.Parameters.Add("@CreateDate", SqlDbType.NVarChar, 50);
    cmd1.Parameters["@CreateDate"].Value = strCreateDate;

    cmd1.ExecuteNonQuery();
}
Wizard1.ActiveStepIndex = Wizard1.WizardSteps.IndexOf(this.WizardStep2);
...

还添加了 using 语句来关闭连接并处理命令和连接。
您应该始终使用此模式正确关闭连接，即使在 using block 内抛出异常也是如此
