通过简单的方法将一种形式的值传递给另一种形式 [英] Passing values one form to another form in simple method

问题描述

家庭作业

我正在使用带有C#代码的Windows窗体.

我有2种表格(分别名为frm1，frm2)
在那个frm1中，我有一个文本框(名为txtbx1)和一个按钮(名为btn_sub1)
在那个frm2中，我有一个文本框(名为txtbx2)和一个按钮(名为btn_sub2)

我运行应用程序，frm1将加载并单击btn_sub1按钮，它将打开frm2，我在txtbx2文本框中输入了一些值，然后单击btn_sub2按钮，txtbx2值将出现在frm1的txtbx1上.

推荐答案

这是用于Form2

Hi,
This is for Form2

namespace FormCommunication
{
    public partial class Form2 : Form
    {
        public Form2()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            foreach (Form form in Application.OpenForms)
            {
                if (form.Name == "Form1")
                {
                    (form.Controls["textBox1"] as TextBox).Text = textBox1.Text;
                    form.Activate();
                }
            }
        }
    }
}

现在是表格1:

Now for Form 1:

namespace FormCommunication
{
    public partial class Form1 : Form
    {
        public string Username { get; set; }

        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            Form2 objSecondForm = new Form2();
            objSecondForm.ShowDialog();
        }
    }
}

谢谢&问候，

在Form1.cs中文件添加以下代码...

in Form1.cs file add following code...

public string val { get; set; }

private void btn_sub1_Click(object sender, EventArgs e)
        {
            Form2 f2 = new Form2();

            f2.Show();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            method1();
        }

        public void method1()
        {
            if (val != "")
            {
                txtbx1.Text = val;
            }
        }

在Form2.cs文件上，添加以下代码...

On Form2.cs file add following code...

private void btn_sub2_Click(object sender, EventArgs e)
        {
            foreach (Form form in Application.OpenForms)
            {
                if (form.Name.Equals("Form1"))
                {
                    ((Form1)form).val = txtbx2.Text;
                    ((Form1)form).method1();
                }
            }
            this.Close();

        }

享受编码...
