Question

我错过了一些东西，但我找不到。以下是我收到的错误。大多数输入（例如票证编号，问题编号）来自会话变量。我输入的唯一输入是“分辨率” txtbox。其他字段是可选的

这是我的代码，可在出现错误时将其插入。

 private void InsertResolution()
    {

         Int32 intRetValue;

        intRetValue = clsDatabase.InsertResolution(Convert.ToInt32(chkNoCharge.Checked.ToString()),
            Convert.ToInt32(lblTicketNo.Text.Trim().ToString()), 
            Convert.ToInt32(lblProblemNo.Text.Trim().ToString()), 
            Convert.ToInt32(lblResolutionEnt.Text.Trim().ToString()), 
            txtResolution.Text.Trim(), txtDateFixed.Text.Trim().ToString(), 
            txtDateOnsite.Text.Trim().ToString(), 
            Convert.ToInt32(drpTechnician.SelectedValue), 
            Convert.ToDecimal(txtHours.Text.Trim().ToString()), 
            Convert.ToDecimal(txtCostHours.Text.Trim().ToString()),
            Convert.ToDecimal(txtMileage.Text.Trim().ToString()), 
            Convert.ToDecimal(txtCostMiles.Text.Trim().ToString()),
            Convert.ToDecimal(txtSupplies.Text.Trim().ToString()), 
            Convert.ToDecimal(txtMisc.Text.Trim().ToString()));

        if (intRetValue == 0)
        {
            lblError.Text = "New resolution INSERTED.";
            lblResolutionEnt.Text = (int.Parse(lblResolutionEnt.Text) + 1).ToString();

        }
        else
        {
            lblError.Text = "Error inserting new resolution.";
        }
    }

这是我班上的代码
