Winforms：组合框高度在分辨率更改时不调整

Question

我在表单中有一个基本组合框。与其他控件（按钮，标签等）相比，分辨率更改时，组合框的高度不会改变。

public partial class Form1 : Form 
{ 
    string result; 
    string fontInformation; 

    private bool scaleFactorKnown = false; 
    private SizeF scaleFactor; 
    public Form1() 
    { 
     SizeChanged += Form1_SizeChanged; 
     InitializeComponent(); 

     label1.Location = new Point(12, 36); 
     label1.Size = new Size(100, 21); 
     label1.Scale(scaleFactor); 

     // 
     // textBox1 
     // 
     textBox1.Location = new Point(133, 33); 
     textBox1.Size = new Size(100, 21); 
     textBox1.Scale(scaleFactor); 

     // 
     // comboBox1 
     // 

     comboBox1.Location = new Point(250, 33); 
     comboBox1.Size = new Size(100, 21); 
     comboBox1.Scale(scaleFactor); 
     // button1 
     // 
     button1.Location = new Point(365, 32); 
     button1.Size = new Size(100, 21); 
     button1.Scale(scaleFactor); 
     // 
     // radioButton1 
     // 

     radioButton1.Location = new Point(480, 32); 
     radioButton1.Size = new Size(100, 21); 
     radioButton1.Scale(scaleFactor); 
     // 
     // checkBox1 
     // 
     checkBox1.Location = new Point(586, 33); 
     checkBox1.Size = new Size(100, 21); 
     checkBox1.Scale(scaleFactor); 
     // 
     // textBox2 
     // 

     textBox2.Location = new Point(26, 102); 
     textBox2.Size = new Size(660, 250); 
     textBox2.Scale(scaleFactor); 

    } 

    private void Form1_SizeChanged(object sender, EventArgs e) 
    { 
     if (!scaleFactorKnown) 
     { 
      scaleFactor = AutoScaleFactor; 
      scaleFactorKnown = true; 
     } 
     Size controlSize = new Size((int)(comboBox1.Width * scaleFactor.Width), 
      (int)(comboBox1.Height * scaleFactor.Height)); //use for sizing 


     //set bounds 
     comboBox1.Bounds = new Rectangle(comboBox1.Location, controlSize); 

    } 
} 

我曾尝试方法Scale（）扩展所有其他控件，它为其他控件除了组合框。我也尝试手动更改绑定，但它没有工作。我也尝试改变锚和码头。

1. 预期结果：组合框高度（在150％）= 42
2. 实际结果：组合框 高度（在150％）= 28

希望得到关于如何解决这一问题的任何帮助。

您必须设置ComboBox到false的IntegralHeight属性：

comboBox1.Location = new Point(250, 33); 
    comboBox1.Size = new Size(100, 21); 
    comboBox1.Scale(scaleFactor); 
    comboBox1.IntegralHeight = false;
