  最简单的方法是添加一个新方法，让我们称之为ShowWithDetails：

  public void ShowWithDetails(double Counter, double Narrow, double Broad)
      {
          CounterLabel.Text = Counter.ToString();
          NarrowLabel.Text = Narrow.ToString();
          BroadLabel.Text = Broad.ToString();
  
          ShowDialog();
      }

  一种方法是在第二种形式中创建一个新的构造函数 . 你可以使用第二种形式的那些值 .

  public Form2(decimal x, decimal y, decimal z):this()
  {
     this.TextBox1.Text = Convert.ToString(x);
     this.Label1.Text = Convert.ToString(y);
     etc...
  };
  

  从主要形式

  Form2 frm2 = new  Form2(x,y,z);
  frm2.Show();

  创建一个新表单...

  public class CalculationResultForm : Form
  {
      public CalculationResultForm(){}
  
      public decimal Counter
      {
          set { labelCounter.Text = value.ToString(); }
      }
      public decimal Broad
      {
          set { labelBroad.Text = value.ToString(); }
      }
      public decimal Narrow
      {
          set { labelNarrow.Text = value.ToString(); }
      }
  
      private void OkButton_Click(object sender, EventArgs e)
      {
          // This will close the form (same as clicking ok on the message box)
          DialogResult = DialogResult.OK;
      }
  }
  

  然后在现有的表单按钮单击处理程序...

  private void MyButton_Click(object sender, EventArgs e)
  {
      CalculationResultForm resultForm = new CalculationResultForm();
      resultForm.Counter = _counter;
      resultForm.Narrow = _narrow;
      resultForm.Broad = _broad;
  
      resultForm .ShowDialog();
  
      Application.Exit();
  }

  有一篇描述how to do this without using ShowDialog()的博客文章 .

  一种简单的方法是使用属性 . 您要将值传递给的表单只是另一个类 .

  将这样的内容添加到第二种形式：

  public int counter {get; set;}
  

  那么从第一种形式开始你就会做一些事情

  Form2 form2 = new Form2();
  form2.counter = 1;
  form2.ShowDialog();
  

  或类似的规定 .
