C# : size in properties is diffrent from code

Question

我在属性中为标签的大小设置了 (100, 100)，并在代码中为另一个标签设置了 (100, 100)。

但是尺寸不同。(代码标签比另一个大)
还取决于我的代码，两个标签最粘在一起。但结果不同!

这是我的 Form1.cs:

using System;
using System.Drawing;
using System.Windows.Forms;

namespace BBSquare
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            Label cell = new Label();
            cell.Size = new Size(100, 100);
            cell.Location = new Point(100, 0);
            cell.BackColor = Color.Blue;

            panel.Controls.Add(cell);
        }
    }
}

这是我得到的结果: (左侧标签的大小为 (100, 100)，位置为 (0,0)

**编辑:这是我的 Form1.Designer.cs **

namespace BBSquare
{
    partial class Form1
    {
        /// <summary>
        /// Required designer variable.
        /// </summary>

        /// <summary>

        /// </summary>
        /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }

Answer 1

您的位置属性无效。在你的设计器中:

// 
// Form1
// 
this.AutoScaleDimensions = new System.Drawing.SizeF(8F, 16F); <--
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font; <--
...
this.panel.ResumeLayout(false);
this.ResumeLayout(false);

问题在于前两行，一旦呈现表单，自动缩放就会启动，您的 label1 将由于 AutoScaleMode 而缩放。这不适用于您在代码中生成的标签，因为缩放是在表单上呈现所有控件之后(以及以编程方式添加标签之前)发生的。 (source)

解决尺寸问题；从设计器代码中删除 AutoScale 和 AutoScaleDimensions(或在设计器中选择 Form 并将这两个属性设置回默认值)。
