本文以实例详述了C#两个窗体之间传递数据的实现方法，具体的操作步骤如下：

1.建立两个窗体，并采用公用变量值传递：

public partial class Form1 : Form //父窗体 {   public string name="";   public Form1()   {     InitializeComponent();   }   private void newBtn_Click(object sender, EventArgs e)   {     Form2 form2 =new Form2();     form2.ShowDialog();     if (form2.DialogResult == DialogResult.OK)     {       textBox1.Text = form2.name;       form2.Close();     }   } }

public partial class Form2 : Form // 子窗体  {    public string name   {      set { textBox1.Text = value; }      get { return textBox1.Text; }    }    public Form2()    {      InitializeComponent();    }    private void OK_Click(object sender, EventArgs e)    {      if (textBox1.Text == "")      {        MessageBox.Show("input!");        return;      }      DialogResult = DialogResult.OK;      Close();    }  }

2.使用地址方式传递

public partial class Form1 : Form //parent form   {    public string name="";    public Form1()    {      InitializeComponent();    }    private void newBtn_Click(object sender, EventArgs e)    {      Form2 form2 =new Form2();      form2.Owner = this;//form2的指针指向form1      form2.ShowDialog();      textBox1.Text = form2.name;      form2.Close();     }  }

public partial class Form2 : Form //son form  {    public string name   {      set { textBox1.Text = value; }      get { return textBox1.Text; }    }    public Form2()    {      InitializeComponent();    }    private void OK_Click(object sender, EventArgs e)    {      if (textBox1.Text == "")      {        MessageBox.Show("input!");        return;      }      Form1 form1 = (Form1)this.Owner;//form2的父窗体指针赋给form1      Close();    }  }
