如何从winform文本框中获取价值并添加到数据库字段

Question

我有两个表（kala，接收）和两个winforms（kala，接收），我想在我填写接收表单（特别是txtqty）并插入数据时，将它（txtqty）添加到kala表字段（txtkqty）中。 我如何在接收表单中的按钮后面编写此代码。 接待表格：

private void btninsert_Click(object sender, EventArgs e)
        {
            string check = br.createreceipt(int.Parse(txtreceptcode.Text),
                                            int.Parse(comboBox_kala.SelectedValue.ToString()),
                                            int.Parse(comboBox_suplier.SelectedValue.ToString()
                                                ), int.Parse(txtqty.Text), DateTime.Parse(dateTimePicker_recept.Text));
            if (check == "true")
            {
                dtrecept = br.getdata();
                dataGridViewrecept.DataSource = dtrecept;
                txtreceptcode.Text = null;
                txtqty.Text = null;
            }


        }

Answer 1

您可以使用以下解决方案：

Form frm = Application.OpenForms["formName"];  
TextBox txt = (TextBox)frm.Controls.Find("textboxName",true)[0];  
txt.Text = "yourValue";  

请注意，此代码并不安全，请自行执行安全性部分（尝试捕获可能是一种很好的方法，也可以通过检查if / else块中易于出错的部分来实现）
