出现错误后不应显示表格 [英] Form should not be shown after raising an error

问题描述

大家好，我已经写了以下代码

Hi all i have written the following code

private void btnEntry_Click(object sender, EventArgs e)
        {

            if (cmbServiceClassCode.SelectedIndex == -1 || txtCompname.Text == string.Empty || txtCompidentification.Text == string.Empty
                || cmbStandardentryclasscode.SelectedIndex == -1 || txtOrgstatuscode.Text == string.Empty || txtODFIidentification.Text == string.Empty
                || txtBatchno.Text == string.Empty)
            {
                MessageBox.Show("Insufficient Data to Proceed");
                if (Convert.ToBoolean(DialogResult.OK))
                {
                    this.Show();
                }
            }

            string s = cmbStandardentryclasscode.SelectedItem.ToString();
            try
            {

                if (s == "CCD")
                {
                    frmEntryDetails frmentry = new frmEntryDetails(s);
                    frmentry.ShowDialog(this);
                }
                else
                {
                    frmEntryDetails frmentry = new frmEntryDetails(s);
                    frmentry.ShowDialog(this);
                }
            }


            catch (Exception ex)
            {

            }

        }

但是，如果我选择某个值 cmbStandardentryclasscode ，则会显示错误消息，但会执行其余代码.

But if i select some value cmbStandardentryclasscode the error message is displayed but executing the remaining code. So can any one please help me.

推荐答案

然后，您是否不想要以下结构(即添加其他)；

Do you not want the following structure then (i.e.add an else);

private void btnEntry_Click(object sender, EventArgs e)
        {
            if ( //the condition checks)
            {
                MessageBox.Show("Insufficient Data to Proceed");
                if (Convert.ToBoolean(DialogResult.OK))
                {
                    this.Show();
                }
            }
            else
            {
                string s = cmbStandardentryclasscode.SelectedItem.ToString();
                try
                {
                    //code as per existing try
                }
            
                catch (Exception ex)
                {
                }
           }
        }

好，我得到了答案


编辑代码如下

Ok i got the answer


Edited the code as follows

private void btnEntry_Click(object sender, EventArgs e)
        {

            if (cmbServiceClassCode.SelectedIndex == -1 || txtCompname.Text == string.Empty || txtCompidentification.Text == string.Empty
                || cmbStandardentryclasscode.SelectedIndex == -1 || txtOrgstatuscode.Text == string.Empty || txtODFIidentification.Text == string.Empty
                || txtBatchno.Text == string.Empty)
            {
                MessageBox.Show("Insufficient Data to Proceed");
            }

            try
            {
                string s = cmbStandardentryclasscode.SelectedItem.ToString();

                if (s != null  && cmbServiceClassCode.SelectedIndex == -1 || txtCompname.Text == string.Empty
                    || txtCompidentification.Text == string.Empty || txtOrgstatuscode.Text == string.Empty || txtODFIidentification.Text == string.Empty)
                {
                    this.Show();
                }

                else
                {
                    if (s == "CCD")
                    {
                        frmEntryDetails frmentry = new frmEntryDetails(s);
                        frmentry.ShowDialog(this);
                    }
                    else
                    {
                        frmEntryDetails frmentry = new frmEntryDetails(s);
                        frmentry.ShowDialog(this);
                    }
                }
            }

            catch (Exception ex)
            {

            }
        }
