C# 窗体间传值

困惑了一上午的问题，被大队一点就通了……大队牛也

比如我要将Form1中输入textbox的值传入Form2中的一个textbox中：

Form1：

 using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;namespace WindowsFormsApplication1{ public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void submit_Click(object sender, EventArgs e) { app.value = textBox1.Text; Form2 newform = new Form2(); newform.Show(); } } public class app//新建的类，为了在其中建立static类型成员 { public static string value; }}

 

Form2：

 

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;namespace WindowsFormsApplication1{ public partial class Form2 : Form { public Form2() { InitializeComponent(); textbox2.Text = app.value; } }}

 

 

 方法二：

 

Form1：

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;namespace WindowsFormsApplication1{ public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void submit_Click(object sender, EventArgs e) { Form2 newform = new Form2(); newform.form2value = textBox1.Text; newform.Show(); } }}

 

Form2：

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;namespace WindowsFormsApplication1{ public partial class Form2 : Form { public Form2() { InitializeComponent(); } public string form2value { get { return this.textbox2.Text; } set { textbox2.Text = value; } } }}
