這篇文章主要介紹了C#實(shí)現(xiàn)窗體中的各個(gè)控件同比自動(dòng)放縮大小,實(shí)現(xiàn)方式主要是利用panel控件為主題,對(duì)于每個(gè)控件的大小位置和字體這幾個(gè)屬性進(jìn)行記錄,然后根據(jù)窗體改變的大小同時(shí)放縮,需要的朋友可以參考下

實(shí)現(xiàn)方式主要是利用panel控件為主題，對(duì)于每個(gè)控件的大小位置和字體這幾個(gè)屬性進(jìn)行記錄，然后根據(jù)窗體改變的大小同時(shí)放縮。

簡(jiǎn)要步驟如下：

1、創(chuàng)建C#窗體程序項(xiàng)目。
2、Panel放置到窗體。
3、設(shè)置屬性dock為fill。
4、注意MinnumSize不能設(shè)置為0，改成大于0都行。

復(fù)制代碼代碼如下:

public partial class FrmDemo : Form

        double dFrmWidth;  

        double dFrmHeight;

                dFrmHeight = Convert.ToDouble(CrlContainer.Height);  

            }  

            foreach (Control item in CrlContainer.Controls)

                    dicControlsAttribute.Add(item.Name, (item.Left + item.Width / 2) + "," + (item.Top + item.Height / 2)   

                                             + "," + item.Width + "," + item.Height + "," + item.Font.Size);
